hot starts on 2004 Dodge Intrepid

Car will on occassion not start when the engine is hot. This is becoming more ofter. In addition it will always set cam/crank position sensor failure in computer after about 10 minutes of running. Have replaced cam sensor and crank sensor. Car has been in accident at 30K miles, currently at 120K miles, issue started at about 95K miles. been fighting it for over 1.5 years. Issue appears to be intermittant, could an occassional open on the harnass cause this, If computer was issue would it always be there or could it show as a cam or crank sensor issue. Is the start issue related to the sensor issues? Would you recommend replacement of wiring harness or computer. Other places I have read that the battery negative could be issue,any truth to this? thanks, Jim

It is likely to be a wiring issue. It may be as simple as a loose connector terminal. I would carefully inspect both Cam and Crank sensor connecter terminals for dirt, corrosion or spread terminals. The connectors can be replaced. Your local Chrysler Dealership can order them for you. Also, carefully inspect the wiring harness from the sensors to the Powertrain Control Module (PCM).
