Question about 1989 Dodge Omni

Car hard to crank and stalling

I own a 1989 dodge omni and it's acting up bad. Some days it runs great others this happens.
It is hard to crank and then after you drive it for a little while it cuts completely off. Some people have said it is the converter. Any suggestions before I replace the converter.

    I have not checked these. The fuel pump in the gas tank is almost new. I just changed it along with the computer and a lot of other small parts. I guess before I do this I'll have my normal guy hook it up to the computer and check it out. Hopefully I am not looking at a lot of expense. I already have a thousand dollars in it.

    Have you checked the fuel delivery system? A clogged fuel filter, loose hose clamp(s), or failing fuel pump could cause intermittent problems. The fuel injectors could also be a culprit. They are not as fun to inspect, but could be worth a look.

    How about the ignition system? Pull the spark plugs and visually inspect them, as they could tell you a bit about the health of the engine. Take a look at the spark plug wires and other ignition components.

Check the fuel pressure if it is low it will be had to start and if it is going out it will shut off because the pump will run hot

Hi

Expensive part to fit, as a guess.!

Have an exhaust gas tested first, this will confirm that the cat converter is shot or not !

Sounds more like a sensor problem to me .

Good Luck !

A FixYa rating would be nice Please !

John.

Please help i have a 1989 honda civic dx manual tranny. For a while the car ran great until one night it stalled and i checked the oil and it was out and i filled it all the way up and started fine and got...


if the motor oil was out I'm afraid the engine was damaged and some bearings of it make now noise and other problems.
then you need to look for a replacement motor from a junkyard or eBay....as rebuilding the engine might be too expensive... 24results for 1989 Honda Civic

Need help troubleshooting 89 omni?


You need a scanner. Does the PCM see the engine cranking?
Are the injectors firing (evidence PCM see's engine cranking)?
Does the system show it is firing? This is things you need to know to diagnosis a a no start/hard starting engine.
I've seen Dodges not seeing engine crank due to bad crank sensors. Usually jeeps.
Good luck and ask more if needed?

Omni stall


I wouldn't think sensor problem. Need to monitor data to see what is not showing up. Some input to the PCM is not being seen. You need to monitor sensor data to see what disappears, it will lead you to the problem.

If the car has current in the plugs and gas coming to the cylinders then it damn well start. Is the car being cranked? if yes, the battery is fine. Check the current in the plugs. The spark should be blue. The fuel pump working?

1989 Dodge Omni Stalls out


A sparkplug wire may have been loosesed or disconnected or damaged.
If you can't find it then wait until late evening when it's dark.

Open hood and start the car. You will see the sparks from the damaged/loose sparkplug cable. Don't touch it while ignition is ON. It will shock you!

If you "disconnected" any sparkplug wires when you replaced the oil pump, then they were not put back in the proper firing order.

Hope this helps!

1989 Z24, 2.8v6 intermittent stalling while driving. Sometimes will restart, but not go far, sometimes will not restart at all. Usually starts fine the next day, may run OK several days before acting up...


the pcm may have a cracked board, i had an 88 cavalier z24 with the same problem, replced the ecu and it ran fine, the problem is that the boards inside the pcm crack and lose connection, the next time it acts up open the glove box and try tapping on the pcm, if the car responds at all, the pcm is bad

Stalled out and won't start now


hi there this sounds like a fuel problem to me if the fuel pump is faulty this will also happen make sure you have a clean new fuel filter in the car and make sure there and no splits in the fuel hose and if all Else fails check the fuel tank if something si blocking the flow in the tank this will cause no fuel to run to the car at all , fuel tanks corrode inside and **** falls in to the fuel which is why you have a fuel filter make sure the out going line in the tank is free from blockage might mean tanking the fuel tank off and having a look or if theres a big enough opening were the fuel sender unit is you might be able to see ther without tanking the tank off

hope this helps thanks for Using FixYa
