javlin 0 Report post Posted April 1, 2010 Hi, As some of you good people know, we have had to replace the engine in our E 34 due to overheating. Part of this process involved replacing the gearbox wiring loom which became damaged while removing the engine and box. We have put everything back together and have tried to start it. It spins freely but does not fire. The battery is new. We have checked for spark and there is none. Fuel is also not pumping through. (We have added more fuel to no avail) . Given that both the fuel and ignotion systems have failed simoultainously we are wondering if the computer is at fault. I have read the appropriate "sticky" which deals with the two systems separately. Any hints greatly appreciated, before we haul the thing off to a mechanic!
