Have you checked Google I found this hopefully it's not your timing or it may be flooded but doubtful have you tried spraying starting fluid into the intake while cranking it
Try this next time you start it.
Turn the key to the run position, do not start the engine. Wait 3-5 seconds and turn the key off.
Turn the key right back to the on position and wait for 3-5 seconds. Turn the key off.
Repeat the above one more time.
Now try to start.
If it starts right up you have a fuel supply problem. Either the fuel pump is bleeding off or the fuel pressure regulator is leaking. Pumping the pedal is doing nothing besides buying time for the fuel system to pressurize.
Post an engine size and I'll help you locate the fuel pressure regulator.
Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!
It sounds like your fuel pump is overheating. Once it gets too hot the bearings swell and the pump locks up. When it cools, they contract and the pump works again. It is also possible the fuel pump relay is having a thermal failure. You can determine this by hooking a voltmeter into the fuel pump supply wire and keep it where you can see it while it is running. If the voltage goes down and then the truck stalls, it would be the relay, if the voltage goes down after the truck stalls, it would be the fuel pump. Since the pump is only running when the engine is running, once the engine dies it'll turn off the fuel pump so it is important to pay attention to what happens first.
check the fuel pump and see is working properly, if the pump is good than the problems will be the crank sensor is faulty. what crank sensor does it sense the turning of the flywheel and it send a single to ecu, and ecu send a flow of power to turn on the fuel pump as long it sense the flywheel turning.
My 94 ranger had a problem of starting when it wanted and running bad. I took it to a ford dealer and they replaced and ignition sensor and fuel pump sensor and it did the trick. On the ranger they are located in a fuse box just behind the battery. They are 1in square black pull out cubes. If you find where they are at,go to part place and ask which on is the fuel pump sensor and the ignition sensor, replace it it makes it go like a new one ,if this is the problem. I almost replaced the fuel pump,because that is what it felt like, a bad pump. Boy would that have been a mistake. Good Luck, JOHN from Oregon
