So we checked again with a noid light and the injectors are getting power but not very much you can only see the noid light work if the lights are off in the garage and it lights up very dim
Injectors won't pulse not getting power
- Thread starter Backyardmechanic1
- Start date
If they are lighting up, they are firing. During cranking the pulse width is very very short. So the noid light does not get the chance to get very bright. You mentioned that you tested for fuel pressure. What pressure did you have? With Fp and +B jumpered and the ignition on you should have 33-40psi.
I don't remember exactly how much pressure there was but it was good and someone told me to change the tps as that could be why there is low voltage to the injectors
Don't waste your time with the TPS. That person is talking nonsense.
If you think you have a weak injector supply, jumper 12V from the battery to the brown wire at the injector resistor pack on the driver side fender. Make sure your jumper wire has a 15A fuse.

I did that nothing changed there is a plug on the drivers side fender I can't figure out what it goes to its right in between the diag box and the resistor any idea what it goes to or if it has anything to do with injectors it's yellowish white and has 4 pins
Depending on which theme you are using the colors might be different, but the buttons are the same.

This will open a box that will allow you to select pictures from your computer.

That would be the connector for the Headlight Cleaner Relay. It's not tied into the engine management systems, so nothing to worry about.
I got it running I believe it was either the connection to the block on the negative battery cable or a bad ground at the tail shaft of the tranny thank you to everyone that gave advice and helped me out

Kinda pisses me off because there are some of us that come in that actually appreciate the help and check the things we're told to check and rule them out. I just now put two and two together from his new thread with the same problems that he previously solved by the neg battery cable or bad ground at tailshaft of tranny:

After reading the other thread, no. There is no injection, as mentioned in this thread, with out the STA signal, and after that Ne and Ks.
