I just replaced the head gasket on my Z28 and now it won't start. I made the mistake of not marking the fuel injector connectors when I took them off and now I'm not able to identify which plug goes on which injector (esp. injectors 6/8 and 5/7). The wires all seem to be the same color. Is there any way to identify which injector plug belongs to which injector? Thanks.

it is batch it does not matter.

What is batch? Don't the injectors have to fire at a certain time?

Batch= more than one fire at a time.
In this case, the 4 on pass fires then the 4 on driverside fires. 4 at a time.. Vice versa bla bla bla..

Forgive my ignorance on this, but do I understand what you're saying--that all the injectors on one bank fire at the same time (e.g. 2, 4, 6, 8 then 1, 3, 5, 7)?

yes, drk blue and pink-black wires on one bank and drk green and and pink-black wires on the other bank.

Great. Thanks. I guess I can rule out the fuel injectors. One peculiar thing I noticed is that the fuel pump stays on for about 30 seconds after a failed start attempt, where I think it usually goes off after about 5 seconds. I'm not sure why. Is it possible to cross the fuel supply and return lines on the intake manifold or are they idiot proof too?

Okay, I checked the fuel pressure at the fuel rail while cranking and it's at 45 psi. I checked and rechecked the configuration of the plug wires on the distributor and the spark at each plug and they're all getting spark. Set the #1 piston to top dead center with the whistle tool and the timing mark and the rotor is pointing right at the #1 cylinder. All I'm getting is a couple of cylinders firing and then it stalls.

Any ideas? This is so frustrating.
