Re: SR20DET diagnosis
[QUOTE=minboostS13]If youve already read this on FA ignore.
I drove to PA this weekend to help a friend find out why his SR wont start. This is what i found:
The wiring harness was absolutely rediculous. It was stripped and loose from the firewall to the ECU. There were spliced wires e-taped not soldered and heatshrunk. They were mingled and confused. That was the first problem.
I pulled the plugs to find that ALL of them were SATURATED in oil. The car hasnt been started, and the oil was still sticky and wet.
I replaced the plugs, reset the timing, and went to check for codes from the ECU. The only problem with that, was the ECU was getting no power. No clicking under check mode, no flashing, etc. I also noticed when turning the key to accessory, that the fuel pump wasnt getting power. I checked it and found there defintely was no power to it at all.
So i got curious and pulled the ECU out and yanked the cover off to find that the whole inside of the ECU was white, with a phosphorous like substance. Almost like battery acid. One of the pins was so corroded, it actually broke off.
So obviously i need an ECU (62) and an SR redtop S13 wiring harness. Anyone know why the cylinders are soaked with oil, other than valve stem seals?[/QUOTE
