Question about 1990 Mitsubishi Montero
I've checked the fuel pump and it works good. and I have good spark, but the injectors arent being activated to open. I checked the oil pressure switch and it works good. not sure what else I can check. cranks fine and have good spark, and fuel pump is fine....???
Check the injector pulses with an osciliscope. If you arent getting a pulse check the ecu. I have cooked 2 of them. One killed my ignition but had good fuel. the second time it wouldnt open the injectors but had good spark. A quick check is to take the ecu out and take the cover off. then look for burnt electrical components.
