Our 1994 LHS is running great. Recently the engine shuts off while we are driving or when we are stopped at a light. The engine would start up again when we put it in neutral or park but recently it will have to sit about 1 hour before it would start again. We have replaced the fuel pump, CAM sensor and the MAP sensor but have not eliminated the problem.

Does it turn over very slowly, if so it would be your starter motor, have that checked first

you have a typical lock up selanoid problem in the transmission. very comon on these th125 type of transmission. replaced many in our shop before

if this unit has an over drive tork converter the tork converter or the TC valve (solenoid) might be faulty, have you tried keeping your foot on the gas a bit to keep it running ? and what happens ? also some engines have a low oil pressure warning and engine cut out , did you check your oil ???

It does sound like fuel pressure is low or intermittent. Here are some check procedures p172 on

Is the check engine light showing a trouble code on the instrument panel? That may pin the trouble down.

suggest change crank sensor-rear of engine pas side

let the engine to cool

it's either a spark or fuel fault , if there is spark after it shuts down it is a fuel fault. connect a pressure gauge in the fuel line, start the engine , note fuel pressure around 35 psi , stop engine , pressure should drop a little then hold, if not check pump return valve and pressure regulator , check fuel flow , if low replace fuel filter,

check the iac i sounds like it is acting up

I checked another site that had a possible solution. It told how to check the ignition switch. After performing this check I decided to replace it. Still no go. The only other thing I could think of was possibly a loose or broken wire somewhere. After looking it over I decided that tracing the wires would be too much trouble.

My solution was to by a remote push button starter switch. I'd just run a wire from the battery to the switch and from the switch to the starter. As of this writing I'm still in the process of installing it. I did manage to "hot wire" the starter and it started fine. That's what lead me to believe the problem is in the wiring. So this remote switch should work.

ignition control module shuts car off when gets hot and will start after it cools on a 94 its under coilpack easy fix
