Hi all -
I have a 1987 pathfinder with the 2.4 engine. I'm having an issue getting it running again. It seems like there is no fuel coming out of the injectors. There is fuel pressure. The fuel pump is working. I checked the ECU code and it comes back 43 which is either Open Injector Circuit or Throttle Position Sensor. It will start with fuel in the throttle body or starter spray but dies out as soon as that burns off. I feel like it is an electrical problem, because my son may or may not have jumped the truck off backwards at one time or another. Before that it was working fine. I thought I would find a blown fuse or relay, but so far I've found nothing amiss. Checked relays with 9v battery and multimeter. Any ideas on where to start? How to check signals to the injectors? Check the throttle position sensor? I'm not sure where to go next.
thanks!
