There is a little black thingy on the key... about 1/4" long... put a meter on both sides. That will give you a resistance number... then translate...

1 402 386 - 438
2 523 502 - 564
3 681 650 - 728
4 887 850 - 942
5 1130 1085 - 1195
6 1470 1411 - 1549
7 1870 1795 - 1965
8 2370 2275 - 2485
9 3010 2890 - 3150
10 3740 3590 - 3910
11 4750 4560 - 4960
12 6040 5798 - 6302
13 7500 7200 - 7820

Andy my new used VATS does not respond to my old key. I assume I have to find what other code will let the system actuate.

the key is most likely worn, or, the sensor inside the ignition is bad.

Using the key chip, get some resistors and match the resistance... then, under the dash, there are to very small wires with a small connector... jump them. I will research for more accuracy.

Check valve... common failure point.

I gave up on junk pumps and bought one from Racetronix... really nice part.

The one my son remove was from Racingtronics . I will find what is causing the pressure loss if in have to replace every fuel line.

If you had a real leak, there would be stink... check the injectors, too.

I would bet on the check valve in the pump.
