Answer I helped my mechanic change one on my 1999 Tahoe and it was not easy. I can also hear the fuel pump hum for a second when the key is turned on. I got 80 psi and it still dropped off when the pump disengaged. I'm also getting fuel spraying out of the schrader valve when depressed on the line going to the throttle body. Made from tough, rigid material.
I wanted to replace the fuel pressure regulator as I have told they all go bad. I know the problem can be a number of things with so many variables, but I think it just needs fuel. I have an 83 Chevy Crew Cab with a 98 Vortec 454 and had a custom wiring harness built. If you remove the regulator, take note of which direction the clip is facing because it will only go back on one way. I also tried a suggestion to test the regualtor by pinching the return line and checking to see if pressure held.
Check cold start fuel pressure. Walker Products supplies the automotive aftermarket with premium engine sensors and fuel system components. Trucks with either the 5. I initially tried running the pump for 60 seconds to prime the lines and I heard something that sounded like an air leak under the hood. It sounds like you did a lot of modding to put it all together. Turn off the 1998 Silverado's engine and open the truck's hood.
These have the ability to adjust fuel pressure for maximum efficiency and horsepower gains. These are direct replacement fuel pressure regulators that feature steel insert on the adjuster to prevent stripping unlike other designs. I also tried a suggestion to test the regualtor by pinching the return line and checking to see if pressure held. With the bad pump, it would start but have no power. I can try that after we get it to come alive again tho! I got 80 psi and it still dropped off when the pump disengaged. You can't see it until you remove the manifold.
Pull the spark plugs and see how they look. I've got a 2000 454 that is loosing fuel pressure when shut off. The vehicle cranks, but no start. Hi Everyone, this is my first post and I find this board very helpful but I still have a couple questions. The fuel rail is the tube that connects all your injectors. Would it be easier to get it to your house. I have a 96 chevrolet C3500 with the 7.
Bob B Hard to start cold. I was told if pressure held, my regualtor was bad, but since it didn't, is it leaking through the injectors. I put the fuel pressure guage on and turn the key to the on position. They now own Delco I believe there is a check valve in there that was failing. Reread the diagnostics chart and then replaced the less than six months old fuel pump which fixed it.
So before I spent 200. We know you love your Chevy C2500 and want to make sure it's taken care of maybe he or she even has a name? Fuel lines are all new except for the flexible hoses off the back of the motor. Along the forward rail you will s … ee at the end of it closest to the driver's side a small cylindrical object with a vacuum hose attached. I took it off and made sure the filter screen was clean and cleaned out that end of it that had crud in that little pipe end that points down. Your talking an hour minimum each way. Search the truck for leaks too.
Its primary function is to maintain a constant fuel pressure at the fuel injectors. In order to keep a regulated flow, the fuel pump exerts more pressure than needed so it can handle the increased flow when the vehicle is accelerating. You must remove the intake manifold to replace it. I have an 83 Chevy Crew Cab with a 98 Vortec 454 and had a custom wiring harness built. Fuel lines are all new except for the flexible hoses off the back of the motor. With as much fluid as I sprayed in there, you would think I would get a little more than a couple pops. It is held on by a clip that can easily be removed with a flat-head screwdriver.
I have a 96 chevrolet C3500 with the 7. Did you have the distributor out at any time? I misread something and so I replaced the pressure regulator but it made no difference. With as much fluid as I sprayed in there, you would think I would get a little more than a couple pops. Later V6 and V8 gm engines should have around 60-66 on most of them. On most 1996 Chevy Tahoes the fuel pressure regulator is actually inside the intake manifold.
