Can you go into detail on the collision you had?
If the wiring from the fuel level indicators to the PCM is fine and the indicators in the tank are good that leaves the PCM and instrument cluster to blame. Does the PCM show the accurate fuel level?
Thanks for asking your question and letting me try to help you.
If your confused on why or how to rate me, let me know.
I'm only paid from the deposit you've made when you rate 3,4, or 5 stars.
Follow up/Reply as many times as needed before or after rating.
My sons and I try to lower the deer population every season.
There are 2 sending units both with the same color wires tan and light blue or dark blue. You OHM test across both wires while sloshing the fuel to see if the reading changes. The signal goes to the PCM first and then is sent out to the instrument cluster.
I like to stay in contact with my customers. I assume you were not pleased with me or my answer since you did not rate it leaving me feedback. Just so you know we can still work on this issue. We can pick up where we left off or start over. I hate you paid all that money for your question deposit and have left not satisfied. Would any diagrams or repair guides or a phone call help?.
