I've been helping blackscarlet get her swap running at it seems we ran into a wiring related issue and the car will not start. The harness was original done by DrTweak many years ago but the swap was never completed and the car sat for a while. Maybe a few 4age gurus on here can point us in the right direction.
Here are the issues. 1. the car will not crank 2. the srs warning light is behaving oddly and staying on even after the key is out of the ignition. I feel like there is a grounding issue going on here. On the 3sgte there is normally a ground wire from the main harness to the back of the intake manifold that provides a ground for the injectors and a few other things in the EFI circuit. I had blacscarlet take a look under the car but she couldn't find any grounding wires on the back of the 4age intake manifold ... is it located elsewhere or handled differently on this engine? I don't have a proper wiring diagram for this motor, just the ones for the car. The cranking issue could be caused by an alarm that is installed. Figuring this, I bypassed the starter relay and supplied my own 12v to engage the starter. The engine cranked without problems but would not fire. Next I tested to see if we had spark, and it seems that we do not. I went on to test the injector harness clips for power, and they did indeed have it, along with the main power wire that feeds power to the coil. I still feel like this is a grounding issue due to the odd srs behavior, or in the worst case, a problem with the wiring harness conversion. Anyone got an idea as to what could be going on? -------------------- 15PSI - 30MPG - Megasquirt Tuned

Lagos helped me replace the fuel pump yesterday and the car is running now.. Still have some issues to work out but at this point I believe everything with the wiring harness is good. The short list: I need to correctly hook up all the vacuum lines, drill holes and mount the power steering reservoir, remove the alarm, and have an exhaust made.. plus a some odds and ends...
But Thanks for the help and Thanks Tweak for doing the wiring harness (6 years ago lol). I will definitely post some updates... Wasn't sure I'd ever see the day of this car running ![]() |
