no spark/injector pulsing

[cbarr300]

and it's not the PIP sensor.

I just recently dropped my engine back in and I'm 100% sure all the connectors are hooked back up like they should be.

I used a noid light to test for injector pulsing and they weren't pulsing. I changed out the distributor to a known good one and still no pulsing.

Can anyone point me in the right direction or tell me how to test the vehicles PIP harness?

also, I cut the wires for the fuel pump on the CCRM (ran a relay). I think it was the: Power to pump wire, input for pump (ground), power from battery, and switched 12 volt ones. Could any of those not being connected to the ccrm cause a no spark/no injector pulsing condition?

btw, I checked all the fuses but which ones should I check again just in case?

thanks

UPDATE: well, I borrowed an ICM from a friend and I'm going to put that on and see if that does anything

I still don't know why the fuel injectors aren't pulsing.

oh yeah, I tried to pull codes....and my code scanner wouldn't do anything.

OK sooo...another update:

after using the handy dandy search button and finding some VERY useful diagrams of the ccrm...I realized my dumb mistake.

basically, when I wired up my fuel pump relay I cut the wire that goes to 13. I thought it only connected to the FP relay....however, that one happens to control the pcm relay.....which controls injectors and all kinds of other stuff.

I'm 100% sure that's my problem...but I'm going to check it as soon as I can get to my car.

just putting it down in the forums in case anyone else has this problem.

This place is awesome

welp, it fixed a few things...but still having the no spark/no injector pulsing

stator is good

Man, I'd like to give you positive input on your problem, but you've already tried everything I ever have. Is there any possibility the new PIP was bad?

I do hope you get this thing solved... Its kinda like ready a :SNSign: version of days of our lives

good luck,

I talked to Clay about it a little bit and I believe he got it all fixored up already (he tore through and did quick diagnostics).

It was a wiring issue.

oh sorry, I meant to update this.

JT, part of my problem was pin #13 for the eec relay. I fixed that and my code reader finally started working (though it didn't throw any codes that really helped me), but I was still having the issues. Well, I was leaning against the connector for my fuel injector harness and I saw my noid light that was still hooked up starting to flash .....checked it and found that I didn't completely bolt it down (d'oh)

currently: Car cranks, runs, and backfires occasionally at idle (I have to get a grommet for my ACT sensor so theres a bit of un-metered air coming in... and I still haven't timed it because I got a bit lazy). My major problem right now is the snapped valve cover bolt and the EZ OUT that's snapped off in it....gotta take the car to a machine shop once I tune it up a bit with the tweecer.

Thanks to everyone that helped

This place is awesome....and btw, that search button works pretty well
