A fault code reader would be a huge help in diagnosing general problems. It plugs in under left side dash and gives specific failure codes (this is what mechanics use).
You can buy an OBD-I code reader (for cars before 96) online for $79.95 or a OBD-II which reads all cars from 1996 on. It will also reset faults or engine trouble lights.

You may want to check your fuel pressure with a gauge.

or do a simple Fuel pump test:

  1. remove the gas cap.
  2. have one person listen in the gas tank at the gas cap opening.
  3. the other person turns the ignition switch to the ON position ONLY (so the dash lights come on.) Do NOT crank or start up the engine.
  4. As soon as the ignition key is turned to the ON position, The person at the gas tank should hear the fuel pump run for TWO SECONDS and then it should STOP.
If it does NOT run for the 2 seconds every time, the fault is either the fuel pump or fuel pump relay

On my 88 Lincon Mark 5 when it is cold it will start but it misses after it starts to warm up it shuts off and has difficulty starting back everytime we go to put it in gear it will die it wont even...


Sounds like you have a bad ign. module. When the engine is cold moisture causes the miss and when the engine warms the module shorts out all together.

My 2000 Neon goes fine for a while then cuts out, misses, and sometimes dies at high or low speeds. I'm going broke having mechanics try out "fixes".


Any trouble codes from it,check engine light? Have the fuel pressure checked. It may read good when first started but after fuel pump heats up from running for a while, fuel pressure may start to drop too low for proper operation. Does it seem to take longer to cut out or act up when fuel in tank is closer to full, then empty?

My 1996 Dodge Ram 5.2 is missing out and dies.


I had an oxygen sensor go out, and my dodge almost wouldnt run, i would reccomend replacing the bad oxygen sensor. The sensor could be telling the computer that there is to much fuel in the exhaust and cuts the fuel down enough to kill the engine, or vice-versa, Another thing could be the Intake air temperature sensor.
