83 ford e350 starts to the start position and then dies in the run position need help

If you jump battery positive to solenoid terminal s the starter should kick in and crank, if not run a separate ground from battery negative to solenoid base if nothing changes check the neutral safety switch with a test light (not a voltmeter). I hope this helps. Take Care.

check ignition switch--battery -cables and connector --solenoid -- power

It's a fuel or ignition spark related problem. You really need to check fuel pressure if this is throttle body fuel injection, and not a carburetor. TBI fuel pressure is not real high, about 15 psi, but if the pump is acting up or the fuel line is clogged, then it won't run good.

Or when it dies and won't restart, jump out and see if there is spark on a plug wire. The ignition system consists of an ignition coil, a sensor of crank position -probably a pick-up coil inside the distributor, and an ignition control module. Or on Fords, I think this is called the TFI module, the little rectangular box fitted to the outside of the distributor, with a lot of wires to it.
So there is some direction for you-gas or spark is not good. BTW, when was last tune-up?

One of your wires is on the wrong side of the starter solenoid. You need to get a test light and figure out which wire goes to the coil and trace it back to the solenoid, switch it from the starter post to the ignition post and you should be good.

Ignition problem... No signal from ignition to solenoid...run a starter draw test to confirm starter is ok --- You can run your jump wires to a remote starter button or switch to get around it for now.

I hope this helps.

it sounds like you have spark in the RUN position, but not in the START position.

try leaving key un RUN position and truck in park wit e brakr applied. Then jump starter at the starter and see if it starts.


if yes, trace circuit from ign switch for start position.

Find the oil pressure switch on the side of the engine block. unplug the connector. Using a piece of wire or a paper clip, jump the connector, thereby bypassing the pressure switch. Start the car and see if it still dies. If it stays running and restarts ok, then you've got a bad oil pressure switch or low oil pressure which will stoop the injectors from firing. If none of this did any good, put the pressure switch connector back the way it was. My next line of thought would be the MAP sensor. If someone hasn't already done so, retrieve the trouble codes from the computer. That would be a big help in diagnosing the problem. If you need help getting the codes, I can try to explain it. One last thought. There should be a fuel pump relay. That relay could be shutting down, then resetting itself when the ignition is turned off. Replace the relay before you try the jumper wire.

replace the oil sending switch on the motor. upon starting the engine this switch has a 3rd wire connected to the fuel pump
when oil pressure is running at its normarl psi the computer will shut that circuit off and then turn on the fuel pump relay

Have you checked it for spark when it dies? It sounds like a bad ignition module.

If you are jumping off the solenoid then it needs replaced. This should fix it. I had a 67 ford truck that did thesame thing and replacing the solenoid fixed it.
