I'm having problems with my 88 coupe when I start her up. Always takes a few tries before it will fire, after that it runs fine. It has no codes stored so I realy dont know where to begin looking. Anyone have any ideas?

It sounds like a fuel pressure problem.

a few thoughts... get a gauge on the rail. expect, when cold, to see at least 20psi. anyless, there is a problem.

try this, too. turn on the key, count to 2, then start. if it fires, the check valve in the fuel pump is bad, and it requires a new pump. however, it's not crucial, so a simple count to 2 will get you by until you want to replace the pump.

I have a gauge and will check in the morning, I have tried waiting a few seconds and that did not help. If I hold it to the floor it will start, makes me think maybe injector but no codes.

I am not so quick to blame injectors.

There is a trick, tho laborious for your car, is to remove the injector rails, and put little paper cups under them, and test fire them. Just to see how the pattern is.

You may want to have them blueprinted, too. It never hurts.

It could also be a clogged filter, but that usually comes into play when hot for some reason.

Has a new filter, put the pressure gauge on this morn. and turned on the key for a second and it jumped right to 40 psi. Started to drop slowly afterwards.

hm... hard start, good fuel pressure...

Is it running rich? Lean?

Do you have the Helm Factory Service Manual? I know it will have all the trouble shooting needed to get through this...

How old is the last tune up?

Another thought, I am a big fan of both Seafoam and BG Products 44K. Try them. I have also heard that Chevron's Techron is a pretty good additive.

Seem to be running a litttle rich, sometimes odor and smoke on startup. I ordered the manuals, should be here today. Was tuned up around christmas time. Will look at the trouble shooting and see if I can fiqure this out. I use techron but have not the seafoam. Thanks for all the help.
