Just bought a 1995 Ford F150 and went to start it to drive it on the trailer and the guy said it was out of gas so I went and got $20.00 of gas for it and reset the fuel pump shut off switch and it started right up for 4 seconds then shut off and kept trying but no luck. Winched it on the trailer and got it home and then the guy told me he had been driving it and it started smoking so he had it towed home then they got it home and drove it in the yard for 10 minutes and ran it out of gas and kept cranking on it. When I got it home I put a brand new battery in it. New plugs and wires in it. New starter and fresh gas. When I checked the oil it was 1.5 quarts low and the antifreeze was empty. When I try to start the truck is turns over slower then usual even with a new battery and starter and it smells like gas and wants to start but wont then after trying for a hours I tried starting fluid and it started for 30 seconds and then shut off. So I tried starting fluid again and no start and then later that day while trying to start it I saw white smoke coming from the rear passenger side of the motor and it smell very unusual and bad. Still cannot get it to start. Don't know what I need to fix.

This sounds like a fuel pump or the crankshaft angle sensor has gone out. When you turn the key to the on position without cranking the engine over can you hear the fuel pump run in the tank for 5 seconds?

This depends on where you have constant spark. Because you are saying there is constant "spark" then I assume this is on the coil wire to the distributor. However if you are saying you have constant voltage on one of the wires coming into the coil then this is a different story. You should have constant voltage on the B+ wire at the coil which is actually in two locations. So we would need to clarify this.

I attached the detail about how this ignition system works for your review. It explains how the system operates and what turns the spark on and off. The PCM is the ultimate control but the vane switch could be the issue as well. However, if the spark is constant from the coil to the distributor then the coil is most likely the issue.

Please let us know if there are questions or what you find.

Lets start with a compression test to see if we have an engine first.

Hello,

With this many miles the compression should be between 125 and 140.

My truck shuts off when driving and doesn't start back up. Sometimes when cooled it will crank. Put new radiator, water pump radiator hoses, alternator, starter, battery, distributor. Can't find my problem I need help.

Hi,

We need to check and see if there is spark with this is happening. When the truck will not restart, pull a spark plug and reconnect the wire and hold the plug against the engine block to see if it sparks.

This sounds like a fuel pump has gone out. When you turn the key to the on position without cranking the engine over can you hear the fuel pump run in the tank for 5 seconds?

https://www.2carpros.com/articles/car-cranks-but-wont-start

I am suspecting that we have a coil issue that it opens the circuit when it gets hot. If you don't have spark, it is either the coil itself or something disabling the coil due to heat.

If you take a look at the attached documents, it will explain how this system works. If we can confirm that there is no spark then we know we are on the right path. Please pay particular attention to the statement where it says the distributor has a Hall Effect switch that controls the coil. These hall effect sensors and switches have a propensity to fail when they get hot. Normally this is found with crank sensors as they are hall effect as well but your truck does not have a crank sensor but it does have this switch.

Let me know if you have no spark and then we can test the coil. If the coil tests okay then you need to rebuild or replace the distributor. Check out the diagrams (Below). Let us know what happens and please upload pictures or videos of the problem.

Have you checked for spark and fuel to the engine? Also, will it start for a couple seconds if you use starting fluid? Take a look through these links. The first discusses the most common cause of a crank/no start condition. The second two explain how to check fuel pressure and for spark. The last one explains how to retrieve diagnostic trouble codes from a Ford OBD 1 system. All you need is a test light.
