When i start my truck my fuel gauge goes strait to full and stays there what are some fixes for this?

 

Welcome to the forum. The problem could be the gauge in the I/P cluster, fuel level sensor wiring (open or short, depending on full on high resistance or the other way around), and fuel level sensor itself. It'd be so much easier if you had access a professional scan tool.

 

i have assess to one but i don't thank it reads fuel problems unless the check engine light comes on and it reads that code.

 

If you can read out what the fuel level is with a scan tool, you can ascertain whether or not the problem is with the gauge in the I/P cluster. There're other things that can be eliminated using a good scan tool.

 

Sounds like you have a code reader not a scan tool. A good scan tool will display live data.

 

thanks for the replys were do you thank i can assess a good scan tool.

 

If you have a laptop, you may want to look into something like the ElmScan 5 dongle (can't get cheaper than that). I've also been looking at the Equus 3150 Innova hand-held unit (or 3160) for when I need ABS codes. It's just that my AutoXray unit does everything I need and is still going strong.
