Sometimes when accelerating to get on highway truck would not accelerate.Ran fuel pressure test and determined fuel pump was bad (shutting key off pressure would drop to 0 psi almost instantly) Replaced fuel pump and connector as these are prone to issues. Truck still has problem. After truck is warm and you let it sit for 30 mins or so it fires right up but acceleration issue is still there. I only notice it after vehicle has sat for a period of time. Any ideas?
Thanx Doug
