Question about Cars & Trucks
Checked the fuel pressure. it read 55 lbs. ( needs 60 to 66 lbs. to start) I need to check the fuel pressure regulator next before I change out the fuel pump.
If the pressure holds steady than the regulator is likely not the issue. It is very common for the fuel pumps to be the source of this issue. Many times you can start the engines with a shot of carb spray and the engine will continue to run after until you shut it off.
Get a quality fuel pump. Either a delphi or an A/C Delco. These pumps are worth the extra money as they are more reliable than most of the other aftermarket brands. One in particular to stay away from is a brand called Airtex.

probably not fuel filter . probably going to have to remove the upper intake and replace the fuel injector spider(fuel inj assebly) if it is droping fuel pressure it is leaking into the upper manifold

Check for a burned fusible link under the hood. If you have power at the fuel pump relay, you could have a bad ignition switch or bad oil pressure switch...accordianman

When you hook the pressure test guage to shrader valve on fuel rail what it reads is what the pressure is from pump, around 60 p.s.i. all you need to do is hook up the guage and turn on key, you do not have to turn engine over, and if pump is good it will shoot up to 58 or 60 right now.
