So i have a 2000 chevy silverado 1500 4x4 with the 5.3L V8. I have replaced the seals on the injectors, new fuel pump, new fuel filter and new spark plugs and wires.
The issue i am facing that i cannot figure out is why im still losing pressure in the fuel. It is no problem when it is cold it fires right up. But when its warm and i leave it shut off for more than five minutes, it takes three or four cycles of the key to start. I know im losing pressure but i do not know where or how. there is no fuel leaks anywhere that i can see. and with replacing everything i am stumped and need some help.
