No power to the ecu
My car started up with no problems last night. I went to start it today and it wont even crank. The cel wont pop on with the key in the second position which means the ecu isn't getting power. I threw a charger on the battery, let it charge for a little and tried starting it. With the carger still on while I tried starting it the gauge on the charger didn't even show a sign of voltage being drawn.
I had a friend wire in an o2 sensor but he left the wires exposed and while the car was running yesterday one of them grounded out on the block and began sparking. I shut the car off, moved the wires away from the block and didn't try starting it until now. I'm running a p05 right now and it doesn't read for a heated o2 sensor, I swapped it out for a known working p75 and the same things happened. Both the ecu fuse and the starter signal fuse are good.

Re: No power to the ecu (hmtcrxsir)
I found the problem...it's pretty damn complicated.
I found that power was leaking from the starter power through the solenoid back into the harness. Everytime I tried starting the car the fan would turn on which was wierd because that shouldnt come on until the car is warmed up. Using a test light, i found that there was power constantly coming out of the little solenoid plug and leaking backwards back into the harness, draining poiwer from everything else and putting it into the fan. I screwed around with that for a while and eventually got the car started. Whats sucks is that the solenoid is internal and now I have to buy a whole new starter

better to replace a starter yourself than to bring it to a mechanic who tells you its something else and charge you a **** load of money to get it fix
