1992 Plymouth laser runs good when cold until it is shut off then doesnt wont to restart loses spark on cyl. 2and3 is this a bad coil or something els

have you check for your back pressuire ,check the catalyst converter might be bad

same answer for all cars made 1920 to now.
never restarted ,ever ? gee , a little hint...?
1: lost engine compression hot, (gee forgot to do the 60k serviice/)
2: lost spark , yes, check spark at all 4 cyl. if bad check coil spark.
3: lost fuel or too much fuel called flooding.

one removes a spark plug, it drips of fuel , say all 4.
flooding.
crank motor at WOT, wide open throttle to clear flooding.
if the spark is good and the spark tips are dry, then try test fuel
if car starts and dies. then you lost injection.

easy huh> with the above you know exactly why it fails.
compression bad
spark
fueling.

1991 i think is TBI single injection engine, i can look it up but
no i wont. we need to do the tests first to get there.

change ignition module

sounds like a bad ignition module check for spark when it dies if you do not have spark at plugs check between coil and coil wire if still no spark most likely module it is under rear of distributer cap resembles a black wafer board with two electrical plugs

you have a bad ignition power transistor.

any time you replace the fuel pump you MUST replace the fuel filter. Sounds like it could be a couple of different things. Pick up coil if it has a distributor. bad coil pack. Replace fuel filter first .Good Luck!!!!

its quite possibly the crank angle sensor as they do this when they heat up,the car wont start,till it cools down,you can get the resistance checked on it to see if its ok,but you will need someone with experience to do it but its not a hard job

It sounds like a clogged fuel filter

Hi!
Start by charging the battery completely. Then, start your car and while running, remove the NEGATIVE battery cable from the battery. If the car dies, your alternator is bad. If it keeps running, reinstall the battery cable and turn the car off. Check for something that's on that would drain your battery like a light in the trunk, glove box, etc. that wont shut off.

ignation control mogule,wen get hot expend and lose conection and will not start after cool down start normal also will cose no fuell presure fuell pump will not run,locatiom under coils.replece it
