Does it fire with a little air intake cleaner sprayed in the throttle body?

Injector pulse?

That is my guess.

Didn't try to spray anything in the TB. Their was no spark so didn't want to waste my time. They should have the ECU tomorrow so we should know something soon.

Good. That's not a good idea IMO

Well not sure what was wrong with my ECU. Called PSI this AM they said they were going to send me out a new one Programmed to my specs at a discounted rate. Can't complain since I didnt buy the kit directly from them new. Hopefully when I get back into town next week I can get it installed and try to fire it up again.

So I got the ECU back today. Fans stopped coming on right away so that's the only good news. Engine still will not fire. I added two more grounds.
Guess ill have to have someone come over and check the car out.

will the knock sensors not let it fire if they are bad?

What else could it be am I missing something.

OK

#1 is the fuel pump coming on when key is on position? With key on push schrader valve of fuel rail to verify you have fuel pressure to the fuel rail. Or if you hear pump running with key on turn key off and check. There will still be pressure in the fuel rail.

How is your fuel system plumbed?

#2 Does the Ignition Relay Click when you turn the key on. If you have to pull the pump relay and have some turn key on and listen for relay click.

There are 2 grounds on the PSI harness that mount to the rear of the heads.

I assume crank and cam sensor are connected?

knock sensor will not keep it from starting

Finally changed the coil wires around and it fired for a sec. The injectors are clogged. You can smell stale gas when we pulled them out. The fuel must of been stuck in the rails for a year or so. Can they be cleaned easily ?

depends on what it is Jason....that long if open might be corrosion due to moisture. I'd start by pulling the rail and popping out the injectors and inspect the inlet side. your getting closer.

Take a syringe (meat injector works good) and some rubber hose. Slide the hose over the inlet side of injector, fill syringe up with carb/brake cleaner, rig up wires to a battery. I used alligator clips and connected one end to the neg post, and one end you will use to intermittently touch to the positive side to operate the injector. As you cylce the power for the injector, push the cleaner through the injector. There are various videos on youtube showing this procedure. I did this on mine to clean them. Hope this helps. I'm having a similar issue with mine, although mine wants to run for a coupe seconds and then pop and backfire and die out

Did you swap the coil harness from side to side?
