Cranking but not starting sometimes.

2001 F150 5.4, this is a hard problem to define. Every so often when you go out to start the truck it doesnt start but it will crank. Then if you wait about 30 minutes and try again it runs fine. Has recently had a new fuel pump and filter, and alt. put in. problem stayed the same. When you turn the truck off the check engine, water, and oil lights lights, and little dashs across the odometer light up and stay on until you press in the brake pedal. I let the lights stay on for a couple hours once to see if they would shut off on there own but they didnt.:screwy::screwy::banghead::banghead:

Your truck should have the OBD-II system, buy and/or borrow an OBD-II scanner box and see if any codes were tripped and stored in the engine computer, data jack should be under your steering wheel somewhere.

I've had other cars checked by autozones little computer thing, is that the same thing?

Yeah, same thing.

they said it had no codes? Also forgot to mention the battery gauge and the fuel gauge stay active on the dash until you press the brake?

If you have a after market remote start I would check that or disconnect it I have had problems with mine when I disconnected it the problem went away good luck

Nope dont have one of those but thanks anyway!

okay i have a 95 ford f150 does anyone know how to replace the clutch switch on it or where it is located i could really use the help

Cranks no start

Sounds like short in ignition system - two shorts really suince one causes 'hot lights' to stay lit after you shut down and the other causes intermittent no start.

Mebso a relay because the 'hot light' problem is solved by activation of brake light circuit.

Seek to fix the hot light problem first, other may follow

Clutch switch

With HYDRAULIC CLUTCH LOOK NEAR THE CLUTCH MASTER CYLINDER.

With a hydraulic clutch look near the clutch master cylinder. With a mechanical clutch, look near the pedal.

check your spark plugs maybe there fouled out, and u said the filter and pump were changed? maybe the pump has a short sumwere, and ya check the ignition sytem to
