change pick up coil in distributor check the triangular points on the round part that triggers the pick up coil corrosion and degrading material common problem requires distributor removal and disassembly of the distributor
In order to answer this you need to be more specific as to what fuel problem you are having. Is it a fuel pressure problem? or a fuel injector problem. I would suggest you go get the fuel pressure checked to begin with. That can usually tell you if the fuel problem is from the fuel tank to the fuel rail or if the problem may lie in the fuel injectors. A weak fuel pump or a clogged fuel filter may be the culprit. If your pump is good and the filter is clean, then one or more injectors may be clogged not allowing the fuel to get to a cylinder. The fuel pumps job is to deliver the fuel to the injectors, the fuel injectors are designed to deliver the fuel to the engine beit through a throttle body or a bank of injectors or single injectors made for each cylinder. Start with a fuel pressure test and see where that leads and then come back and repost.
the fuel pressure is around 30psi
No, the fuel would still be pumped to the engine but it would be at the wrong pressure at the injectors.
Possible weak fuel pump. The fuel pump will pump fuel to the engine, and if the engine's demands are greater than what the fuel pump can deliver, the motor will stall. Let it sit for a few seconds and the pressure builds back up. Turn the key, same cycle happens. The fuel pump needs to keep a certain pressure to the injectors. have a pressure test done to see if you have a fuel pressure problem.
41 to 47 psi with pump running, engine off. The injectors are operated electrically.
Not much info to go on but, do a fuel pressure test to se if you are getting the proper fuel pressure to the injectors. Year, make, model and engine size would help us help you.
This is a device that measures the pressure of the fuel that is to be delivered to the fuel injectors. This measurement is used by the engine control computer to determine how long the injectors need to be driven open to deliver a specific amount of fuel.
should bo on top of engine in the fuel rail by the injectors
I have no number on panel when icon checks oil pressure . please guide me what is problem
V6 engine - 6 fuel injectors V8 engine - 8 fuel injectors
It may be a simple leak-down in the fuel pressure regulator. Sometimes when the pressure regulator leaks there won't be pressure to the injectors when you try to start the engine. It's not a big deal, and certainly not worth spending a lot of money on the problem if it's nothing more than this. Test the idea by turning on the key for a few seconds, turn it off, then try to start the engine. If the pressure regulator is allowing the fuel pressure to leak down, this simple procedure would allow the fuel pump to build pressure BEFORE you try to start the engine. Then when you DO try to start it, hopefully it will fire right up.' Good luck. I hope it works for you.
The standard fuel pressure for a 1998 Chevy 3500 with a 454 engine is 50 PSI. If fuel pressure drops much below this level, the fuel injectors will not work properly.
