Does this sound like a bad fuel pump?
Does this sound like a bad fuel pump? 2 days ago my car became hard to start. It would crank for 4-5 seconds before starting. But once started it ran fine. I noticed it doesnt sound the same when priming. This is only from a cold start btw. Warm start its fine. Im not down on power, idle isnt fluctuating. Im going to change the filter, but it was changed less than 4K miles ago. What do you guys think?
Prob the check valve in the pump has a slow leak so every time you go to start it it has to reprime itself. I think it is fairly coming try priming it acouple times first before tring to crank see if that solves it. Also with the gauge you will be able to tell once the car shuts off if it holds pressure or not.

Verdad Gallardo Yea then its your check valve you will be able to verify this once a gauge is on it. You can see how fast pressure is bleeding off mine was almost instant. Sounds like its time for a new pump or you can just live with it like that until it goes out.
ok since the filter is out ive narrowed it down to the relay or the pump. i primed the pump 3 times, car started right up. the whine is very faint now. pulled off the vaccum line on the regulator at idle, no smell of gas or trace of gas, so thats out. 2 of the 5 prongs in the regulator are bronze, rather than silver like the other ones, not sure what to make of that. going to replace that tomorrow, see what happens

Do what everyone else has told you and put a damn fuel pressure gauge on it! No LT1 owner should be without one.
