Truck wont start problem.

I have a '05 Cat. C-15. Lately, it has started and run for two to three minutes and dies like it is out of fuel. I can crank the engine, excessively, and it will start and run normally. This happens when I let it sit for five plus hours, definitely, overnight. It has been suggested that it is a weak fuel return check valve. But if fuel is draining from the engine, why does it start and run for two to three minutes?

 

Uses fuel left in lines and bowl then cuts off I guess.

 

OK, but where would the problem be?

 

in the check valve like you were told, its a simple fix. just replace the check valve.

 

Yes the check valve. It's nothing but plastic, ball, and a spring

 

Do you really believe that. I've run probably every type of fuel filter you can buy on my truck

 

OP if replacing the orings doesn't fix the problem, check your solenoid and the starter. You can try the old screwdriver trick to turn it on just turn the key to the on position and make sure parking brake set.

 

3 years ago, I bet he got it fixed.
