No spark, I've searched, I'm lost.
Back ground:
The car is a 1988 stock 3.2. I just recently dropped the engine, transmission, and a bunch of suspension components. I replaced a lot of stuff (including ref, speed, and CHT sensors). Since then the engine has been running but I have been chasing a cold idle hunting problem. The engine ran about a day ago. Since it last ran: I replaced the Targa seal (seats are out so maybe I stepped on the DME, I've reassembled the front end, I did some metering of the idle switch, open throttle switch, AFM temperature sensor, and I've attached a fuel pressure gauge. I then jumped the dme relay to activate the fuel pump to read pressure when the engine is not running. Then I tried to start the car but no joy. As far as I can tell I don't get a spark. What I've checked: -Fuel pressure builds every time I start it and it stays pressurised but bleeds a little. I've removed the fuel pressure gauge incase it was somehow causing the issue. -12V at the one side of the coil with ignition switch on -ICV hums when ignition on telling me the DME/ECU is getting it's power -metered out the coil as per Bentley but every thing seems to spec. -I've metered the speed and ref sensors and they are to spec. I know that it's not a definitive test but they are new. I'm all ears. |
Solved:
I must have stepped on the DME at some point. I thought back to my childhood Nintendo days. I uplugged the big DME connector, blew on it, and plugged it back in. Worked like a charm. |
