No start when raining.
Well im sick of my truck not starting when its raining out. The problem is when the truck has been sitting in the rain for a couple of hours it doesn't like to start. I have fuel pressure at the rail, I have spark, I have crank. BUT the fuel injectors are not firing. Now I have it narrowed down to either a GEM module, ECM, Ignition control module, a cam synchronizer or cam position sensor. I have already replaced the Mass air flow so thats not it. Now which one would cause the injectors not to fire and nothing else. Once the truck is started it runs like a champ but it depends how wet or humid it is. if its a little damp out the truck will crank n crank n crank and finaly start after a little but if its pouring out for like two hours no way in hell will it start till its dry. If anyone can throw me some input or ideas it would be appreciated.
