99 suburban fuel pressure problem?

Here goes. My fuel pump died on me about a month ago, so I replaced it. I know that was it because it would make gringing noises and not the usual high pitch whine. I could not get the engine past 3000 RPM right before it died on me. When it died there was no whine, at all.

So then I ordered a completely new gas pump (Delco), with the seal and the new wiring that is not supposed to heat up like the oem wires GM didn't recall.

I dropped the tank, installed the new pump, lifted the tank back up, and everything seemed to work just fine.

The wierd thing is that when I try to start the engine on the first crank, it will not turn on. It seems as if I have to let the pump do the whining noise that it does before I can start the engine, for the engine to receive fuel.

I have never heard of anyone having to wait for the pump to send fuel to the engine first, being able to start vehicle up. runaround

Then the engine starts up.

I was thinking that maybe the pump is not in tight enough?
Or one of those plastic gas evaporation tube broke off?
Maybe there is a fuel pressure loss some where I was messing around with when I installed the pump?:uhoh:

The fuel filter is new, so I dont think that has anything do do with it.

Any help anyone? :1zhelp: It would be appreciated. Thanks!
