ok inoticed fuel pump was not coming on, has done previous so checked fuel pump fuse it was not blown but there was no volts to it. the relay is new as well. the fuel pump was not coming on when ignition was turned.
no volts on plugs leading to injector rail or pin 12 on ecu.
put a earth feed on pin 3 ecu and the fuel pump came alive. car turned over and checked fuse for fuel pump and it was running 13v. car continues to run whilst earth is on pin 3. when earth is removed car stalls.
question, is problem within ecu circuitry? there is power on other pins so assuming power in is ok.
the other thing i noticed was the top of the ecu that flips open so pins can be seen, if this is moved whilst car is running with the direct feed to pin 3 then car stalls. so i am assuming that there must be circuit problem.
there are companies that repair ecu’s may give them a call’
any other idea?
