Fuel Gauge and Check Engine Light
 

All,
I have gotten alot of help and am in need again. I have a 06, F350, 6.0 LB. I have had new head gaskets put in, studs, Banks Six Guns and just had all of the O-rings, Stand Pipes and Dummy plugs replaced. I have been having this issue for a while now and believe it is the fuel pick up sensor. What happens is periodically when you start the truck, the fuel gauge will not register and the check engine light comes on. Let it run and sometimes the fuel gauge will register and show you your fuel level, but the check engine light comes on. Sometimes you can turn the truck off for a few moments and turn it back on with no issues. Any thoughts, any suggestions??? Please help, it freaks my wife out when she goes to get in it and sees this!!!:w2:
