Its strange but after my truck sits over night after it rains or snows it will not start.

Its like it loses prime somehow. I crack and injector and I cant get it to start, but if I give it a shot of starting fluid it will pick right up and run fine until it rains again.

Starter fluid is extremely dangerous unless you disable the manifold heaters.

 

Well once again it has rained and now it wont start.

Yeah I know using fluid is bad but thats the only way I can make it start and yes the heaters are unplugged.

 

Rain is water which interferes with the ignition system & spark plugs. You ain't got on spark plugs so consider rain irrelevant. Start searching for fuel leaks.

My CKP acted up & caused intermittent no starts. It was as if fuel wasn't getting from VP to injectors. AirDog kicked to 15# as normal. I didn't hit it with ether so don't know if it would have started. CKP didn't throw codes.
