pureboiracer 0 Report post Posted October 16, 2007 ahhh man. problem after problem. ok so the deal is my e30 with its newly aquired m20b25 engine with motronic 1.3 system is in.. everything is fine. exept the fuel pump doesnt run. i am running the old (pre facelift) body loom along with fuel pumps. i have narrowed down the problem there is power in both parts of the fuel pump relay. if i bridge it the fuel pump runs. the ground from the low current side of the relay goes to the ecu wich then grounds it accordingly. so i have been testing wires. i have established that the grounds from the ecu are fine. and the ecu is receiving a signal from the igniton to turn on. so i think the problem may lie within the ecu..... can anyone tell me anywhere i can get my ecu tested or weather i should just get a replacement? or does anyone know of anything else it could be??? any help greatly appreciated cheers oli Quote Share this post Link to post Share on other sites
