Dodge Ram 1500- Engine Dies While Driving

Vehicle Problem: Vehicle was towed in to shop. Customer complained of engine would die while driving and now would not start at all. 1996 Dodge Ram 1500, 5.2L V-8 engine, Automatic Transmission

Solution: As with most No Start situations that come into my shop we start with checking the basic 4 elements needed to make an engine run. 1) Spark 2) Fuel (including fuel pressure and injector pulse) 3) Compression 4) Timing We found that we had weak spark and intermittent fuel injector pulse. Since the plugs looked old and the distributor cap had signs of corrosion, I replaced the Distributor cap, rotor, plugs and wires. We now had good spark. The vehicle would start and run and then die. Since it would start, I now look to the sensor side of the engine. No Check engine light on the dash and no hard codes were set, but after checking the soft codes(history codes) it had a Crank Sensor Code. Replaced the Crank Position Sensor and the vehicle ran great unless you put it under heavy acceleration and then took your foot completely off the gas. A quick test on the IAC let me know it needed replaced. Replaced IAC and All is back to normal. Customer Happy ! Parts and Labor Cost $ 600.00 plus tax.
