Fuel Issue - FPR or ECU
I am encountering a fuel delivery issue on my recently acquired 91 240 wagon. Twice now I've had the car either stall and refuse to run or barely run enough to make it up a small hill in my neighborhood during test drives. Both times the car was fully warmed up.
I replaced the main pump (it looked like the original pump), in tank pump and strainer. The fuel pump relay was very hot when it decided to run like crap. Note the car has the 561 ECU which I believe is not too reliable.
I plan to get a new fuel pump relay (for insurance) and I do have a 946 ECU in my parts bin. Will that work in the 240 (it was originally from a N/A 940)?
Thanks!
