Ford f-150 was not start cause of water - 2001 Ford F150 Styleside SuperCrew

Check fuel pressure. Bad pumps will work, just not enough pressure. If the engine light is on, check codes. Your's has a fuel pressure sensor and module that could go bad.

use a better quality HT lead with a long insulator would be a start but it would be best to replace the corroded housing

replace battery.may have a bad cell

It may the same problem water does not compress may be trying to lock up the motor and causing the starter to struggle to start the engine.

If you are handy, it will take about a day to replace the water pump. You can download the service manual from

Make sure to read the instructions for removal and replacement before you start.

Start with a good coolant flush.(This should be done every 2 years anyway). Next move to (check or replace) the thermostat and then on to the water pump. Check all water hoses for hardness or blockage. (Bottom radiator hose should have a spring in it). Last, with your head behind the raised hood , idle the engine at about 12-1400 rpm and listen for the clutch fan to come in or go out. Good luck.

1 of 2 places.
1. The windshield on the driver's side towards the lower corner. This is the more common location, and causes water to run down the a-pillar, and drip on the cab fuse panel / GEM

2. The less common location, power roof panel. Some times this will have an issue and water will run down the a pillar, similar to the leaking windhsield.

change you rad cap first this will cause the overheating and then go from there as this actually sounds like two seperate problem the other sounds like a plugged heater core

if this is shift on the fly 4x4(electronic shift),check all fuses first.Try lightly tapping on the 4x4 electric motor on the transfer case,if it changes,replace the 4x4 motor.Water and dirt get in the 4x4 motor,causing it to stick.

the small rubber boot around the piston is either off or has a hole, which let water in and rusted the piston to the cylinder

also can be caused by a hot caliper submurged in water
