?87 F-150 5.0 stalled and won?t restart. Electric

’87 F-150 5.0 stalled-won’t restart.Fuel problem. Electric is fine, spark at the plugs. Starts immediately with every shot of starter fluid but dies in seconds as the fluid is used up. The last time it did this, I shorted the fuel shutoff inertia switch and it has run perfectly until this time when the inertia switch has no effect. There is the sound of a relay when starting and stopping the starter. The sound is coming from the high pressure fuel pump. But this fuel pump is not running. Is the fuel pump the problem or are there more safety switches to check? Ideas?

Is the fuel pump inside the fuel tank? If, so, you could try disconnecting the wire harness at the tank, and hot-wiring the fuel pump directly to a 12 volt source, in the correct polarity of course! If the pump runs, your problem may be a fuel pump relay, or a wire problem or connector problem. If the pump does NOT run, post that info. There may be a way around the problem!

SOURCE: Ford Escort 1998 fuel pump not working.

good old ford lol, try looking at the crank sensor its located at the front of the engine tucked in right hand side of exhaust manifold and gearbox, two pin plug, i have also known these to have no end of faults with the fusebox.
easy to remove, and solder the connections inside they all suffer eventually, if your not to handy with cars i recommend taking to a auto electrician, easy if you know how. Good luck Davelee

JD JS45 walk behind mover. Starts, runs fine for 5 minutes, then stalls, won't restart till i pull the spark plug and cool the motor, plug down. then same thing starts, runs for 5, stalls.

Probably either a fuel or a spark problem. You need to check for the presence of a good spark immediately the engine stops - by using a spark gap, a spare spark plug or a propriety spark indicator.

If the spark is found to be absent the fault is likely the ignition module but check all connections and the stop switch operation before replacing.

If the spark is present then the fault is probably fuel-related and is the sort of thing a tiny droplet of water in the carb could cause...

Could be an ignition problem or one of the relays.
When it fails to start, you'll need to figure out if you are missing fuel pressure or spark to the plugs.

1988 buick regal stalls and restarts stalls and restarts

Sounds like a relay or coil failing.
To proceed you would need to find out if you are loosing spark to the plugs or fuel pressure to the injectors when it won't start.

you may have to check the fuel pump function for pressure and volume when this happens as it could be a bad pump,you could have it checked when working as it could show up something but more likely should be done when it stops running.

I had a problem just like that on my blazer and it turned out to be the wire harness on the fuel injectors. It could also be your fuel injectors, had to replce mine at 85000
