    thanks for the reply I did start checking the isc motor 29 ohms that part checked out haven't had chance to take it off and see if the pintle moves properly. If the bad ecu blew the isc motor would the car not idle at all or idle to high all the time? thanks again.

Check engine light on, oil light when idling, blue water light on


I would start this diagnosis by verifying that you do not have a mechanical problem like a blown head gasket or bad turbo. Check the oil and coolant and make sure both are full and the fluid is clean. If the either fluid appears milky you have a severe mechanical problem.
Let me know the status of the fluids and we can proceed from their.

This sounds like you have a plugged "pre cat". This item sits just below the exhaust manifold and is a common item to plug and cause the engine to be
'choked" as so it will not run or if it does run, the acceleration is very very poor. Also if it is that bad and can keep it running fromunder the hood, you should see it glow cherry red. Have this replaced.

I just bought a 1993 Plymouth Laser ES and the lady said the battery was bad, so i picked a new one up on the way there. well. it ran. but i know i need an alternator. well heres the problem, I started it...


hi,

I would put an alternator on it and see how it acts then. it sounds like a combination of things. depending on the model, it may have a malfunctioning or siezed turbocharger. If you find out its not a turbocharged issue I would tune it up, new plugs plug wires, injectors, filters. you probably have vacuum leaks also. Its hard to tell you what to do because there are so many options you may or may not have If it ends up being the turbo AWD model I would have it lubed up immediately before you drive it anymore.

my brother had a mitsubishi cordia and it ran untill he sold it. if you look at wikipedia you can see the similiarities there.

I have a 1993 Plymouth Laser and it wont start. It will turn over but no spark. I tried to do the on ACC on ACC On and the check engine will not blink any codes. Any suggestions?


crank sensor, PCM, or Ignition module could be bad You car may have a ign fuse or ecm fuse that could of popped. Now if your not sure it has spark then you could have a fuel issue. If someones sprays a little brake cleaner in the Throttle body and it starts then you have a pump issue. If it still doeant fire up then you know for sure you have a spark issue.
