Default 86-89 4x4 V6 5-Speed ECU

Pretty sure my ECU is malfunctioning on my 89' 4x4 V6 5-Speed. Injectors are constantly flooding the engine with fuel. Anyone out there got one that I can use? I'm pretty sure it has to be from a 5-Speed 4x4 V6...

Your issue could also be a blown-out injector. That would dump fuel all the time.

You can pull the codes (see my signature below) to see what codes are there. There are codes for bad injectors and a bad ECU.

You can also use an Ohm Meter to test the resistance in the Injectors. I believe the TBI injectors are supposed to be around 4 to 6 Ohms each.
