The only thing left in this system is the fuel pressure regulator. You need to check pressure before the regulator and after the regulator if there is the problem then you need to replace it. I hope this helps. Don't forget to rate my answer.

1997 GMC Savana 1500 5.7 ltr. turns over has 1/2 tank of gas and won't start...even if I floor it I don't smell gas, just won't start. can it be something simple like a fuse...

Hi, the electric fuel pump in the tank may be bad, causing a no start. it should run when the key is turned on, for two seconds, then stay running when the engine is cranking, or running.The pump should put out 55 psi, this should be the first item to check. Good luck...

1999 GMC Savana - changed fuel filter, changed fuel pump, changed mass oil flow sensor, changed fuel injectors; still won't run!

Hi, I see you have changed a bunch of items, but do we know if the engine is getting fuel pressure? (55 psi at test port), or getting good spark? Could the spark plugs be fouled?I think before you replace too many items, you should start with basics. Good luck, Thanks...
