    Hi:

    I've got a 1990 FJ62 with a newly rebuilt engine. Runs great and starts great cold. When it heats up in the sun it won't start. A little work shows that it never loses spark, but that it does lose injector pulse when it heats up [pulses once, then quits].

    So...I think it's probably an ECU problem.

    Questions:

    --anyone have any experinece like this?

    --who carries used ECU's?

    --is it a problem matching ECUs to a specific engine [ie by year, serial number, etc]

    Thanks for any help!

    I would look at the EFI main relay, they are a know possible trouble spot on the 3fe, sometimes when hot they won't start.

    used ECU, I would post in the wanted section here or try Cruiserparts.net

    I very much doubt its the ECU however.

    Would there be a spark if the EFI relay was bad?
