1992 Skylark 3.3l No Fuel through injecto
#1
I have a 1992 3.3 L Skylark that will not run. What we've done so far:
New fuel pump and filter (plenty of pressure at the fuel rail)
Plenty of spark.
New ECU (ECM)
New fuel pump relay.
From what I can tell it seems that fuel is getting through at least one of the injectors (maybe). I took all the plugs out and one was covered in gas, the others were bone dry. I have an injector node tester and I am not getting any kind of pulse with the key on or cranking. I put a brand new ecu in and still no pulses. I am really hitting a wall here and do not know what else to try. What else should we check that would tie into the injectors getting a pulse? We thought maybe the crank shaft sensor, but if that was bad would we be getting spark ? The car itself runs of ether fine.
Thanks in advance.
