Default dies while driving??????!!

1993 lx randomly die while driving,
Either 100miles or .5 mile it will just shut down. Turn the key back while drifting then back to the on position and it runs fine again. Has new crank sensor, ignition switch, icm, ecu, body relay module. Any ideas at alllll? Trying to sell this car but a month of problem solving is killing me. Read codes and it is all good

Have you checked the IAC? All vacuum lines?

Does it just cut off real fast or does it sputter?

It runs with the iac disconnected. Not well but it runs. It seems electrical but I have no idea

Ignition system? Check all hot wires and make sure you didn't shake n' rattle a bolt loose or something. Check your battery and your battery cables too.

Check the fuel pump relay fuse? Sometimes they get hot and short out.

+1 for this, especially since it's a recurring problem.

Where is the fuel pump relay? However it sometimes shuts down 200 yards from my house. It doesn't studder out either and I can smell gas sometimes as well.

Definitely an electrical problem. I doubt its the fuel pump because if it stopped pumping the car would sputter till it stops. Since it happens when your 200 miles out, then its not a closed-loop vs open loop problem. A sudden shutoff of the engine usually indicates an ignition wiring problem. An ignition wiring problem would also explain the gas smell, since raw fuel will come out into the exhaust since the spark plugs aren't firing. Most likely a loose connection, short or bad ground somewhere. Good luck...
