NC Tom Posted April 23, 2023 Author Share Posted April 23, 2023 UPDATE: New Plugs New Fuel Pump Restored Injectors Distro Okay Spark Test Light = Have Spark Noid Light Indicates Injector Pulse Okay New CPS (not sure about readings) New Fuel line rings and clips at rail I have spark and weak fuel delivery. A decent amount of gas drips from the pressure regulator when vac hose detached. I can reinstall the old CPS if anyone thinks that's an issue. I'm thinking the Fuel Pressure Regulator is the problem. But, I'm a woodworker, not a mechanic. Link to comment Share on other sites More sharing options...

It only leaks if you disconnect the vacuum line. For this issue, should there be gas in the vacuum line? Link to comment Share on other sites More sharing options...
ratrapp Posted April 23, 2023 Share Posted April 23, 2023 my bad,i thought i read you didnt have fuel leaking out of it.damn i shouldnt read without glass's on lol.and no there shouldnt be any fuel in the line ,period.this causes fuel to go straight in the intake every time the key is cycled on.thats probably why the fuel pressure drops so suddenly.

howeitsdone Posted April 23, 2023 Share Posted April 23, 2023 Fuel and air should only be in the same room during combustion... or the fuel tank, I suppose. It's $40 on Amazon Link to comment Share on other sites More sharing options...

ratrapp Posted April 23, 2023 Share Posted April 23, 2023 you may still have other issues even when you fix this but it needs to be addressed before anymore repairs or attempted starts are made.after you put the regulator on and see that it holds pressure you may want to hold the throttle open some to see if it starts.it may be partially flooded from the leaking regulator.and no,holding the throttle open an an efi vehicle won't flood it.the throttle body is nothing but an air flapper.
