2001 Ram 1500 5.2 L
when truck sits for a couple of hours it has to turn over for about 8 seconds before it runs. It seems like the fuel pressure is bleeding down as it sits. I replaced the fuel pump thinking the check valve was bad. It did start correctly for 1 day. So I figured that check value was bad so I put in a inline check value. This didn't help at all.
My next step is to get a pressure guage hook it up start the truck then record the pressure. Let the truck sit , not running and record the pressure every 30 minutes. To confirm there is a drop.
Anyone have some advice?
PS this is my 16 year old girls truck and she don't like it starting like this. If it was mine I would just luce with it.

I did use a pressure gauge first. I didn't see a sudden drop in pressure. But after truck had set for a couple of hours there would be air coming out of the bleed valve before the truck would crank.

That doesn't always mean the fuel pump. It could be a connection is bad or there is a hole in the fuel line.

Mine was a plugged fuel filter, the computer turns on the pump for a quick shot of fuel prior to starting. ****ty part is you have to drop the tank (or remove the bed) anyways to replace. I found a complete fuel pick-up unit (new pick-up screen, new fuel pump, new fuel sender, new fuel filter) from Rockauto for the same money everyone else wanted for a fuel filter. Mine would bleed very similar. You could also leave the key in the run position for 2-4 seconds (this allows the fuel pump to chance up). This worked for me.
