Question about Cars & Trucks
It seems taht I have replaced all the right parts but I have no solution yet. I used a screwdiver to listen for the "click" noise while the motor is running and it works but it fails the fuel purge test and when I get on the gas hard it sputters.
I'm just trying to get as much information before I kind of give you a guess. Now you say no electrical power yet it "clicks". Have you or disconnect the connector to that injector. With the key to the on position (not running), at the red wire (using a separate ground such a the battery) are you geting full power there ? Now at the white wire on that same connector using a seperate power source; in other words on your test light clip the "aligator" part of the light to the positive battery post and the "pointy" part of the light to the connector where the white wire is. Now as you turn the engine over or even if it's runing on the other 7 injectors are you getting a pulse or flicker at a regular "rate" not once in a while ? Last at the PCM harness (I know you said you replaced but am just starting from point A to be sure) at "pin" location 101 (see picture below), from that location check the resistance at that connector (pin 101) and at the connector at the injector at the white wire. You should pretty much be zeroed out as far as continuity with an ohm meter. You can also do that test to see if you are getting the same "ground" pulse by plugging in the PCM connector and checking there (carefully) to see if you are getting the same pulse there as you are at the injector connector. It should be the same. You can check with another injector to see if it tests out different. You may have done this already but as I said am starting from square one. I don't know it all but happen to be a Ford electronics specialist. Are you getting any trouble codes ? Feel free to comment back here or you can email me directly at email@example.com and I will do my best to help and no there is no cost for my help. Here's the PCM connector:
