I can't tell you how many times I have heard that. If the fuel pressure is too high, the most likely cause is a bad fuel regulator or a clogged fuel return line. If that doesn't do it, Im not sure where to turn. Hello: Thanks for giving some input here, it is all learning in some fashion. I am planning on the fuel pump. But with pressure at the limit of not being enough, anything is possible.
I won't run at all right now unless using ether so theres no way to test your second suggestion. Im fairly mechanically inclined, but this one is will have me baffled if its not the fuel pump. Our local Chev dealer can't keep enough pumps in stock at times. To check the fuel pressure specification, you'll need a fuel pressure gauge, a small tool available at most automotive stores. If there are no obvious leaks anywhere.
As soon as the fuel pump shuts off, it drops to 20 psi. Its been my experience with electric fuel pumps, they just go out without warning. Mine did the exact same thing, same model year but with the 5. If it still doesn't hold pressure, then the Fuel pump is bleeding back into the tank. Any help would be greatly appreciated! It made no difference in my case. With attributes and models that satisfy or pass the requirements of their original equipment.
If your vehicle is running rough at idle and getting very poor gas mileage you should first check the basics: vacuum leaks, spark plugs, plug-wires, distributor cap, hoses and wires. Do not wait for your car to experience performance loss and risk unanticipated breakdown. I was looking more at the fuel system for the problem since the fuel system is vacuum regulated. Any help is greatly appreciated, and thanks ahead of time. Starts great, runs at idle. Turn off the 1998 Silverado's engine and open the truck's hood. Once it is replaced you never know when it will go again.
I hate it when a post just ends, so I figured I would give it some closure. Also, instead of the arc marks on the poles being lined up with the center, all of the marks were to the side of the poles on the cap. If I start out, it will have good power and sound normal for about a half of second, then you can feel the power drop right off and the engine just doesn't sound right. I love the trucks they do what I need them to do. Mine does not have a gas smell or black smoke. If they are both marked, you should be fine though. Testing the fuel system unless he has a good set of gauges with a long hose so he can run it inside the cab.
The pump should be putting out nearly 60psi. I Replaced the fuel pump 6th time in 4 years This last time it still would not fire up and I suspect the regulator at this point as the pressure is good at the pressure relief valve. If not atleast tape it to the windshield. I will check out the ignition coil, thanks. I honestly don't know how it even ran with the gear as bad as it was. But I don't know 100 percent sure it was correct to start with.
I did notice the exhaust sounds a little too muffled though. I will be tackling the fuel pump tomorrow. If I don't, the camper won't be getting towed. This last pump is now another Delco, I have also had Carter's and Re-tech's. Although it didn't completely fix my issue, Im sure mine wasn't helping at all. I've heard the intake has to come off in order to change it however. There's the difference, but the symptom will be the same.
My older ford van has it, and if the low pressure pump in the tank goes the high pressure pump will only draw down to half full. Do I actually have to do a tear down of this engine to get to the regulator? That pump may come with a float. But did inform me that I could schedule an appointment, a week out none the less and get a diagnosis to the tune of 300-400 bucks. The original pumps will last, on our Sub the orginal went to almost 150,000 miles. It turns out, my cat was slightly plugged and the egr valve was weak. Post Reply print what i posted. The actual temp is fine, but when you lift the hood, it really smells hot.
