C4DERF	She died on me yesterday! But SHE IS ALIVE TODAY!!!!!!	#1
Senior Guru Home of the Masters; well Grovetown is close 332 Posts Member since: 2007/12/30 0:00	My 94 LT1 auto coupe just shut off as I was driving to work yesterday morning I do not have nor know how to pull any codes, guess this will be a good time to learn! I was driving along at about 25mph when the engine simply shut off. The engine turns over very strong but there is no attempt to fire. I have more than 3/4s of a tank of premium gas in her and all other fluids are good. Does anyone have a suggestion on what to look for and also suggestions for an inexpensive code reader to purchase? Thanks gurus!

There was no spark from the coil, so I replaced the coil. That didn't fix it, so I put in a new ICM and it fired up.

An ignition module or coil can open up from heat and quit working, but they also tend to work again after they cool off. You can get a timing light, or pull a plug out and ground it on the engine (but leave the wire hooked up) and check for spark while cranking to see if the ignition is working. It might also be a dead fuel pump. Get the car in a quiet place and turn the key on (not start) and have someone listen under the tank in back, they should hear the fuel pump hum for 2 seconds as it primes the system. If you're not sure, turn the key off and wait 10 seconds then try it again. You can also check for fuel pressure at the schrader valve on the fuel rail, or just poke the stem to see if its under pressure.

CentralCoaster: The check engine light is ON, don't know if it came on just before the engine died or not. when I put the ignition switch in the ON position I can here the fuel pump run for approx 2 seconds then shut off. I have not started any diagnostics yet as I wanted to get my hands on a code reader for the 94. Thought I had one today but when I read the book it was for 88 - 93 vettes and not the 94. I plan to do some reaserch tonight on the net for a decant priced reader for OBD I & II (94 & 95 vette). I will also try to get my hands on a 16 pin OBD II connector to make a multi useful tool. Anyone have a reader they would be willing to loan me!!?? Thanks guys as I will try to do some troubleshooting Friday night.....

Means nothing now. When you cycle the key to on/run the light will stay on as a default to make sure the bulb functions. Same with all the other idiot lights. Start simple. As was stated, check to make sure you have the simple things. Fuel/Air/Spark. If you are getting fuel, the plugs will eventually be saturated and you will be able to smell it one them. You can also check pressure at the rail via fuel pressure gauge. Spark, do as suggested. Just take an old plug, pull the plug boot and lay it on top the intake manifold. And have somebody start the car while you watch, or do it in a dark garage.

I knew that, but it excaped my mind when I was writting the reply, thanks. I will try the old plug trick and it looks like I will be investing in a fuel pressure gauge also.

I thought mine wasn't working at first, but after talking with the owner of the site (nice guy, BTW), he straightened me out. I'll probably buy a scanner of some sort down the road (I have a lot to learn before that will be useful), but this gizmo does a good job with the codes, and basic info such as when you're in open/closed loop, etc.

Many people start changing out parts chasing codes and spend a lot of unnecessary money. Autone can be a useful place as you're looking checking parts as they can test them for you. If you don't have a service manual get one and follow the trouble shooting list to test for problems with a multimeter. The codes will give you suggestions and a starting point, not necessarily a solution.

Even a high dollar scanner won't get you the answers if you don't have the diagnosis flow charts. Yep, a bunch on money down the drain by replacing unnecessary parts. Especially coming from the forums: "It could be", or what came up all the time on the other forum: "I have a miss"------"It's gotta be the Opti"

I ran the scan with a reader and all it tells me is "Failed" I ordered my own and it tells me it can not scan because it can not read the software. ANYONE have aby ideas? My thoughts are the ECM died. I have fuel, oressure to the fuel rails, bleed the schrader valve. Not sure about fire from the opti as I am doing the troubleshooting by my self at the moment. I am still looking for a good buy on the FSMs. Thanks for your ideas gurus.

It could be another problem.

Note: I think the contacts in the C4 may be in different locations from Dan's Impala. Go here and check the connector and your emission lable. http://www.actron.com/faq_detail.php?pid=16152&id=18 I think your code reader may not work in your 94. You really need that FSM.

I do like this approach, simple and easy to remember (Pirates of the Caribbean) If you didn't get the multimeter yet, it's obviously a good idea to spend $10.- for a cheap one. Test all the fuses and go from there. Just the other day I had an ECM I couldn't collect data from. Weird part, the computer connected but no data, go figure the fuse was blown. The engine would turn over strongly but no fuel.

WRT the CD service manuals, I've never known of legitimate FSM's anywhere. I've heard some folks unhappy with the ebay service manuals, and you might wanna' skip on those. If there's a real FSM for '94 on CD, I'm IN. Lemme' know where you find it... I got only Book 1.

Little steps in the right direction lends to improvement in all aspects of her health. Thanks for asking. Last night I managed to do a spark test. Pulled the # 2 plug boot and cranked it several times without producing any fire. Sure am hoping it's not the opti but if it is, oh well it is. No quick fix on this it looks like. Somebody suggested that if I replace the Opti I need to go ahead and replace the water pump also. I'll keep pluging away a little at a time.. More to follow soon.

Fred, I am still getting the updates on Nichole in my email and it is great to see the progress she is making. On the other hand I still feel like the drunk sob that hit her should be nailed to a tree upside down and worse. The opti is a possibility, but I am agreeing the the ICM or coil are more likely. The opti usually gives warning with rough running symptoms before it just crashes. I have done an opti twice, not fun, but not nearly as bad as a lot of people make it sound. Let me know if I can help. Andy

She has a dr visit tommorrow with her plastic surgeon. He is a wonderful man and one heck of a fine doctor. As for the ICM I pulled it the other day to look it over. I didn't see ab physical damage, but then I really wouldn't know what to look for. tjpreul sugested taking the ICM to an auto parts store3 and said they could check it out. Just curious but how would they check it? Is it something that could be done with a multimeter? I will try to check the ICM tomorrow after work as I will be out of town this weekend. Thank yous to everyone. This is an experience. fred

Elite Guru The hills of N. Georgia 2424 Posts Member since: 2007/12/30 0:00	Fred, as I understand it the ICM has to be heat cycled 10-15 times to be tested. I would guess that takes some equipment that you would not have on hand, When I replaced my opti 2 1/2 yrs ago I also did the ICM and coil just as preventative measures. Never had it tested. The factory ICM on ours is riveted to the bracket, but new mounting bolts came with mine. The 'goo' behind it is a heat sink and necessary to keep it from overheating and burning out. Not saying to 'throw parts at it' like I did, just saying the little I actually know about it.

Thank yous to everyone. This is an experience. fred Yes, the ICM can be checked with a multimeter. But without the diagnosis chart, it's probably easier to take it and have it checked. Hopefully the parts store guys know what they're doing. You can check the ICM plug wiring by connecting the meter to "A" and a ground and to "D" and a ground. Both should have 10 v. minimum. The ign.key has to be on. I don't think that the heat cycling's going to be necessary at all since you have a no start condition. It would matter if the car was shutting down while you were driving.

If the parts store can't properly check the ICM, you can do it with a mulitmeter but depending on the readings, there's 2 charts to go thru. P/N for a 92, AC Delco is D1971A, GM 10483131, I'd double check these for a 94. I'd definately check yours before replacing, they run $130. Also, if your replacement doesn't include grease, you can sub dielectric grease, it's just a heat conductor.

I ran the scan with a reader and all it tells me is "Failed" I ordered my own and it tells me it can not scan because it can not read the software. ANYONE have aby ideas? My thoughts are the ECM died. I have fuel, oressure to the fuel rails, bleed the schrader valve. Not sure about fire from the opti as I am doing the troubleshooting by my self at the moment. I am still looking for a good buy on the FSMs. Thanks for your ideas gurus. I think the 94 may not be ODB II. See Dan's post on ODB 1.5 in "Other Vehicles". Note: I think the contacts in the C4 may be in different locations from Dan's Impala. Go here and check the connector and your emission lable. http://www.actron.com/faq_detail.php?pid=16152&id=18 I think your code reader may not work in your 94. You really need that FSM. Yes His 94 like my 95 has and OBDII computer & connector, but is running OBDI You can pull most of the codes up on the dash, so for 90% of the stuff you need, a scanner is not needed. http://s242.photobucket.com/albums/ff ... 20Cunningham/ccm%20codes/ I actually DO have a scanner that's been custom programmed.

I still have not gotten anywhere with the troubleshooting. What I need is a set of the 94 FSMs so I can identify the components and locations under the hood. I popped the fuel rail cover on the pass side but I did not see a coil?. I am not very comfortable just disconnesting things without knowing what I am looking at. If anyone knows of a reasonably priced set of 94 FSMs please post or e-mail me (fcandrews@charter.net). I did a search on the e- and the prices are running around $90.00 +! Thanks gurus as I am still slowly trying to diagnose and repair/replace what ails my vette. Fred

Fred That's not a bad price, I paid more than that for my 92's, I went to Helms for my 2000 Silverado and it's $135. Corvette Central wants $129 for the 94 FSM and that's loose leaf. $90 is cheap if it makes you feel comfortable when you get under the hood.

The narrow red arrow is pointing at the ICM and the wide red arrow is pointing to the coil. Please excuse the dirt, guess I need to do the spring cleaning in the engine bay sometime soon. Carol and Brett got a beauty in the new vert, I love that color. Hope the can sell the FRC soon. [IMG]http://i51.photobucket.com/albums/f386/andyminnich/100_1085-1.jpg[/IMG]

Senior Guru Home of the Masters; well Grovetown is close 332 Posts Member since: 2007/12/30 0:00	95vette, The phot helped a great beal! I removed the coil and power sterring resivoir. We took a trip to O'Reilley's and had them test the ICm and it was bad!?! Special ordered a replacement ($105.00 + tax=$113.and change). I bought a new coil also $14.00. It took me about 30 minutes to remove the rivits from the original coil securing it to the plate and installing the new hardware. Said a prayer and she fired up on the second hit of the starter. What a beautiful sound!!!!! Took her out for a little test drive (hehe 22 miles later). She ran like a champ. Now I need to get hold of an OBD 1 sanner that can reset the "Check Engine" light. Sure is nice to have her running again!!! Thanks to all the gurus with their most helpful suggestions and ideas and diagrams. You folks are the greatest..... thanks....Fred
