Unplug the injector electrical connector.
Using an ohmmeter, test the injector resistance across the injector terminals. The reading should be approximately 12 ohms at 68°F (20°C).
If the resistance falls outside specifications, replace the faulty injector.
If the resistance is within specifications, proceed with the testing.
Place a 12 volt test lamp across the injector's electrical connector terminals. Watch the test lamp while cranking the engine and compare with the following:
If the test lamp does not flash, check the power feed and ground circuits between the PCM and the injector connector. Refer to the wiring diagrams in Chassis Electrical for wire colors. If the circuits are faulty, repair them. If the circuits are OK, test the engine control system using the Chrysler DRB, or equivalent scan tool.
If the test lamp flashes, proceed with the testing.
Check for fuel delivery at the suspect injector by removing the injector from the fuel rail and check for fuel and/or restrictions in the rail or injector fuel inlet. Compare your results with the following:
If there is no fuel present at the injector, replace the plugged injector, or clean the restricted passage, as necessary.
If there is fuel present at the injector, proceed with the testing.
With the injector removed from the fuel rail, connect a 12 volt source to one terminal on the injector connector and a ground wire to the other terminal. The injector should click each time the ground wire is connected and disconnected to and from the terminal.
If the injector clicks, it is OK. If it does not click, it must be replaced.
I BORROWED A CAR WITH SAME ENGINE TO DO THE INJECTOR TEST, IT IS NOT SUPPOSED TO FLASH LIKE TEST PROCEDURE SAYS, MY VAN TESTED JUST LIKE THE RUNNING MOTER!
I have got it to fire a couple times now, I've always held the pedal to the floor the whole time no pumping, I think I will proceed with the oil change, dry out the cyl. Like u said and I think it will start. Try it tomorrow.
And I think tech level 1 is just from answering others posts!
I'll let u know if I get it started
thanks for hangin in w/me
