Injector Driver issue!?!

[vacuum 6]

easy way to trouble shoot mod to ECM wiring?

 

[vacuum 6]

Just asking. I remember you upgrading something.
I have a spare ECM if you need to borrow it.

Chris,

I may take you up on that. What's your location?

 

[TurboBuRick]

Pull the ECM plugs and look for coroasion or broken pins.

 

[Chrisk]

Northbrook. I came out your way once and picked up methanol from you.

I remember you coming for alky. Didn't know where you're located. I'll let you know.

So here's an update. Wanted to check the NOID light again. Getting a fade illumination on all six injector plugs and can smell gas (I may have made an error maybe). So at this point seems like the ECM is next.

 

[Chrisk]

Is your orange ECM wire ok?

Yes it seems fine. Pump turns on etc once plugged it. Unless I'm missing something.

Volt bulb on dash working? Could it be anything with the oil pressure pressure switch plug? I'm just thinking of the small things that may have been overlooked.
Contact Steve Wood on ihadav8.com hes always helpful and has seen it all. Also Earl Brown.

I tried to start again today, runs rough for a sec then does a little back fire (see it on boost gauge) then dies. I'll check the bulb. Thanks.

Volt light works. I'm not using the stock oil psi sending unit...VDO gauge.

ok, so we are getting some fuel.

have you double checked the cam sensor timing.

what chip are you running?. perhaps unplug the MAF and see if it will start.

Bob

I'll check the cam sensor.

Running a TT chip.

Already unplugged the maf and no change. I'm running a LS1 with translator. Would a bad maf or translator make the car act like this?

At this point could we still have a bad ECM?


Walter

 

[TurboBob]

did you unplug the translator from the car, or the MAF from the translator?

yes, it could still be a bad ECM (and even still a bad ignition module, although maybe less likely now).

Bob

 

[vacuum 6]

I unplugged the maf from translator.

Yeah I wanted to eliminate the ignition module however my backup ignition module is bad.

I do have Julio alky kit. Which was off during the testing.


Walter

 

[Chrisk]

Any update?

No not yet. I'll have time this Saturday.

[vacuum 6]

So I think I found the issue. Can anyone see what I am seeing?

Cam sensor off, or timing chain jumped a lot. Looks pretty clean in there. How new is the emgine
