Engine Performance problem
1998 Dodge Dakota 6 cyl Two Wheel Drive Automatic 105000 miles
We have replaced fuel filter and pump, pick up magnet, distributor cap and rotor, ignition coil, the diagnostic tool points toward the ignition coil circut. Help. The truck runs great for a mile then it stalls out. Then sometimes it will run all day with no problem. Your help will be greatly appreciated.
Not sure what you mean " the diagnostic tool points to the coil". If it's electrical or sensor-related, there should be a diagnostic fault code memorized, and the " Check Engine" light will be on. If an ignition coil becomes shorted, the engine computer will shut the drivers down to protect them.
If the air gap is not set to specs on the pickup coil in the distributor, the Automatic Shutdown Relay will not turn on or will turn off intermittently. That will result in no spark and the fuel pump won't run.
You will never solve a cutting out problem on a Chrysler product by changing the fuel filter. The distributor cap and rotor are highly unlikely too. The pickup magnet will never cause the problem you describe, but the pickup coil definitely could. Looks like you didn't change that. Try that first, although you should have gotten a fault code for " crankshaft position sensor". After that, a professional diagnosis might be cheaper than just throwing a lot of parts at it.
