my 1998 4.3v6 blazer wont take fuel when its cold but after the motor warms up it's fine
It has around 55 psi pressure on it but drops about 5 pounds every 5-10 minutes until it goes back to zero
It has a new Delphi pump as well as filter .
Like I said after it warms up it will start and run and accelerate as it should .

You say it drops..is this with the engine running or stopped?
It only drops if it sits for a while and not running.
That’s why it doesn’t seem like a fuel issue all together .
A buddy of mine said to check the temperature sensor that it can cause a rough idle and fuel like symptoms until it warmed up
Does that seem right ?
