2004 Vue 3.5 will not start if gas gauge does not read. If gas gauge comes up, car will start. I was told the connector with the power for gauge and fuel pump was the culprit. I had the wiring harness to the tank swapped with a known good one, and the problem is still
there. Car can sit for a day and will maybe start. Any ideas?

 

Was your fuel pump/sending unit confirmed to be good?

 

Yes, works fine if car starts.

 

I think DD means was it verified fully functional at all times regardless of the gage reading?

 

As I stated, all works well if the gas gage comes up at start. Then the car runs perfectly. I suspect a common power issue with the fuel pump and the gage reading. I just dont know where to look.

 

So then the answer to DDs question is no.

Lemme see what I can find

 

Only Vue post I came across where somebody bothered to actually post the resolution. This may be your issue or it may not. There are quite a few vue 2003-2004 Vue no gas gauge no start posts floating around, so it is not uncommon.

Do not try to use the S Series versions of these posts for troubleshooting, as depending on the year, they may or may not have body control modules.

Oh, the link...
