Has anyone encountered this problem.I have a 02 Ram 2500 4x4 Magnum. Engine cranks over strong,. I thought it mite be the wires, so I changed Wires, plugs, cap, rotor. It does it when it sits for a few days. After a few mins. of cranking, it does start with No smoke or sputtering, it actually runs great, and starts good thereafter. So i was thinking it's Not electrical. Must be FUEL. So is there a check valve that prevents the fuel from draining back. It only does it when it sits for a few days. ANY IDEA"S would be greatly appreciated...................THANKS LOU

 

Does sound like fuel. Can you hear the fuel pump start up? How many miles?

 

Moved to the technical section

 

get a fuel gauge and check the port on your rail, check it running and after it sat for a while.

 

Thanks for the suggestions. Well I just started it and it was difficult.
The fuel pump does sound like its running. Its a short Hum for a few seconds, when the key is turned on. It has 79k miles Thanks again Still perplexed yet.........LOU

 

have you by chance checked the battery do a load test on it to test the battery and charging system

 

No I haven't It turns over very Strong. That's why it seems to me to be Fuel. It does Start but you must crank it way to LONG. then it starts easy there after. Thanks I'm still thinking Fuel pump

 

Well I had to brake down and bring it to the shop. It was driving me Crazy. Will keep you posted

 

Ok ! Here is the Follow up on my problem with my Excessive Cranking issue. When it finally did start and I was driving at highway speed, it would start to brake up some. So i drove it rite to the mechanic. It ended up to be a bad ignition coil it was shorting out. I change everything but that. Boy do I feel like a HORSES ***. ............Thanks to all
