Fuel pump?

[Admmg]

96 Chevy 350 5.7l vortec auto. my truck had a hard time starting. i changed the fuel pump 2 years ago. i changed the fuel filter it helped. i have about 50 lb of pressure at the fuel line. the truck starts ok when i use it threw-out the day. when i leave it over night it dosen't start right away, it will start on the second try, somtimes on the third. i have a new battery in it. any ideas? if it is the fuel pump would taking the bed off be easier then dropping the tank? i droped the tank last time by my self it wasn't fun!

neither route is easy, i have tried both.

it could be a fuel pressure regulator. have you tried pinching of your return line when you test the fuel pressure?

Ill try that.

Siphon out most of the gas then drop the tank

i would go withthe regulator.. i had the same exact probelm in mine. i had to cycle the key in the on/off position a couple times before it would start. changed the regulator and havent had a starting problem since... this was on a 00 jimmy 4x4 4.3 vortec but it is just a smaller version of yours so i would think its the same problem. hope you get it.. it is a pretty easy fix but you do have to pull the uper manifold to replace it. but after that its no problem

How fast does the starter turn the engine over, it may be getting weak and is working harder on the first turn to get everthing moving.......just a thought

The easiest way I've found to change the fuel pump is by unbolting the driver side of the bed and loosening the bolts on the passanger side then ******* up the bed on the driverside to access the tank. The first truck I did I removed the tank it was a major pain. I've done 2 trucks with working the bed this way and found it to be much easier, but that's just my take on it.
