Injector test

[Jetfixr757]

Well folks, eingine is in the car, all wiring hook ups done, fuel, etc, put the oil in and crank till oil pressure on the gage, however, all pistons except #1 show signs of fuel on the piston, i am concerned, that the ECU might be having issues. Looking for suggestions.

I don't know that the ecu you could be having problems... you might go back and check your wiring... or check to see that it's plugged in all the way... just a suggestion...

The injectors are batch fired, so if it's the ECU, two pistons would have to be dry. This leaves the injector as the possible problem.

Snap! I hinted at this in the other thread

Well i was looking at this last night and wondering if the fact that the ISC is right there could that have and effect on ithe system or the number 1 intake runner, i had the injectors cleaned and flowed and all results were good.
Thanks for the response though.

I had a similar problem (bad injector) check that the connections arent correded and also check the wire going to the ecu as that whole wire can be corroded on the inside also. When you put it all back together apply some di-electric grease to all the connections.
