It's common for the map sensor on the car to go bad and will cause the problem that your describing. Locate the MAP sensor and disconnect it and see if it starts, if it starts. Then replace the MAP sensor and most of the time it's going to be along the fire wall on your dodge. If there is an Auto Zone in your area, they can do a part locate for your car and show you where it is so you can check for any damaged vacuum tubes to the MAP sensor from the intake manifold, and at worst you may have to replace it and Auto Zone may have the parts on the shelf or they can order it in if it's bad. Auto Zone can also read the code you have to address the issues you car has. Good luck and hope this helps.

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.

My car cranks but doesnt actually start


When my cars have loose timing belts that usually means the belt has stretched or tensioner may be bad. If the belt was loose it may be a tooth or two off, could be the tensioner. I bought a car once which the people said it had lost power ever sense the timing belt was changed. The shop wanted to charge them another 700 dollars to go back and check. I bought for 800 dollars and found it was 1 tooth off. Ran great after that. Just my thought.

does your cruise control work??? I had no heat or a/c intermittent, and cruise did not work. I replaced the ignition switch (behind the key) and everything works fine now. Switch was 80 dollars and about 2.5 hours of work... the shop wanted 450 dollars.

Hey my omni wont start at the moment. we replaced the distributor cap and rotor and its not the map sensor what else could the problem be please help


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?

I have a 2003 chevy s-10 pickup. The fuel pump stopped working. I replaced it and the fuses are good, but the new pump won't turn when I turn on the key. What should I check?


Check the relay and the wire harness from the frame to the gas tank, The harness is about $15,00 and is common to fail due to corrosion and time. Good luck and hope this helps. Keep me posted

1990 Dodge Omni. Runs but shuts down


Check to see that you have good(bright orange) spark to the spark plugs the next time it dies... if not odds are its the coil. If spark is good check fuel pressure, since the pump was replaced if pressure is bad the fuel pressure regulator would be in question.
