I have a 99 Dodge Ram Van 1500, 5.2 V-8. It has the multi port fuel injection system. The PCM operates the MFI. At cold start it operates in the open loop mode and ignores the oxygen sensors. I have a no start problem. It is the 1st start try in the morning. If I can get it started , it will start right up after the engine is warm. Based on advice, I replaced the IAC valve. That didn't help. There are no codes set.
Here are the sensors that the PCM gets input from in the open loop mode: crankshaft position sensor, coolant temp. sensor, intake manifold temp. sensor, MAP sensor, throttle position sensor, camshaft position sensor. If any of these are defective, a code should be set. I have a code reader and there are no codes set.
Today, I was unable to start the engine. Anyone have any idea why?
