Ok. SO i'm checking out the fuel pump, as it seems to account for the car not starting. I had a mechanic help me check the relays by jumping them and he says they seem to be working right and that it just seemed to be a bad pump. SO, i put in my spare pump (i think its brand new). Well it seems i wired it backwards because no one ever taught me that on European cars, BLACK does NOT mean NEGATIVE and they tell me the ground wire should be on negative and the black wire on positive. So, i switched it, and the car still doesnt start. Maybe i damaged the pump? Can these get destroyed by running backwards? If so, i just killed two fuel pumps. I rigged up a voltmeter to the fuel pump that could be watched from the drivers seat while turning the key. With the key in the first position (auxillary) i get only 0.3 Volts to the fuel pump and it does NOT kick over. When i'm turning the engine over, it gets 9.5 Volts. It seems that this is drastically wrong. Any input would be greatly appreciated. -Craig '85GL
