The mechanic says the truck takes cranking the key about 5 times before it starts over while the gauges are all bouncing. Seems to be an electrical issue any tips on where to start ? The truck just ran fine on a 600 mike trip. The owner has had this issue ongoing for sometime now. Thinking of heading over there and checking the grounds for the battery to start. Currently shows no codes.

 

Turn the ignition to the ON position and have someone sitting in the driver seat watching the gauge cluster.

Wiggle any and all ground and positive connections you can find. Wiggle the 42 pin, PCM, IDM, fuse box wire bundles. If the truck is a 2002+, check the positive junction box under the air box, that is a common corrosion point. Check the batteries with a multimeter when idle and turning the starter, they need 10.5v minimum (Ford says 10.2v) to start.

 

What he said. And listen to the fuel pump.

 

This truck turned out to have major gashes in the passenger side ground to engine block causing these problems and a few others. All battery cables were replaced. Will be inspecting the ground on my truck seems it rubbed on the battery tray the worst For this one.

 

thanks for following up with the solution.
