Engine wont start after swap

hsv08 · Post by **hsv08** » Mon Mar 14, 2016 5:05 am

So got a vx v6 wagon, the motor run a bigend 2nd day i had it.
brought a second hand VS ecotec to swap in. Changed intake manifolds over and bolted back into car.
We broke the top Selector switch pad plug when trying to get it out but the pins were exposed so we plugged the plug back onto the pins (basically the same except it no longer has an outer casing).
all loom is original vx stuff.
Key on i get reds, pump stays running/priming (doesnt stop while key on), iac is moving out or in, starter wont turn over.
Bridging pins 5 & 6 it doesnt register and wont flash up the CE light ( just stays on like normal on reds)
Dash in diag mode it registers the CTS at -40 which im sure means dead?

Any clues or starters on where to look?

The pad on the left hand side of trans, slides over the selector. two plugs, they are normally glued in there. i broke the outer casing of the top plug.

That may very well be part of the problem as I believe that is the start lockout for when you're not in Park/Neutral.

May well be that the pins inside that pug are bent or somehow not connecting properly but i would still have thought i would have got fault codes from the CE light and the pump would only prime to pressure then stop and coolant temp sensor would register actual temp not dead temp...

Yeah it doesnt sound like the computer is running. Check all power supply pins and ignition circuit to pcm first then look for other wiring faults. As immortality said something could have damaged the pcm too.

Hmmmmmm well I will get the other pressure switch thing on side of trans and try that.
Nothing loom wise was taken out of vehicle just in plugged. Flash pcms shit me.
I'll bust out the multi and go checking it out.

I think I have a flash pcm around here somewhere but it would need to be flashed with vats disabled tune otherwise I think you will have to link the pcm/bcm.
