the car doesn't start up at all, fuel pump doesn't spool and the check engine doesn't light up in the ON position for the strter key... when messing up with the wires at the fuse box at the kick panel the check comes on some times and some times it doesn't.
we replaced the whole wiring harness and the ECU yet the problem is still their... i am sure their is something cutting off the power supply to the ECU but were can that be? you see we changed all the harness and the ECU itself, only thing left is the thing were you put the key in to start the car (first time to come accross a car part that i don't know in english

now when the car used to run it was running rich like crazy... black smoak is all over the place and thge exhaust backfires when he is off the trottle... this car was turboed in the past and their were no check vaves on the MAP so could a faulty MAP make the car run rich like hell??
this guy told me the O2 sensor is fairly new so i illiminated it from my diagnosis... he was asking about the crank position sensor though, will it cause any of the above problems if it was disconnected or malfunctioning??
