Are you setting the gap between the rotor and the pump body? .003-.005 each time
If the answer is yes, then check the shaft of the motor. Up & down movement of the shaft indicates a bad bearing and the movement will kill the gap that has been set and cause breakage of the rotor!

85 TOYOTA CELICA STARTS RUNS FOR 5 MINUTES STOPS TRY GIVING IT GAS IT STOPS WILL RESTART EVER TIME AND RUN FOR 5 MINUTES AND STOPS CHANGED FUEL FILTER AND FUEL PUMP DID NOT HELP WHAT DO I DO NEXT


TRY THIS. REMOVE THE INTAKE ON THE RIGHT SIDE OF THE CAR .THE EGR VALVE CLOGS UP WITH CARBON SOMETIMES CHOKING IT OFF COMPLETELY. IT WILL BE HARD TO START WHEN THIS IS CLOGGED. CHUNK OUT THE CARBON WHERE THE BUILD UP IS. REPLACE WITH A NEW EGR.

Poping while trying to start


Over time carbon deposits build inside the engine including the valves, seats and spark plug. Easy to change plugs however not so easy to clean carbon. There are products at auto parts store that you can pour into carb and add to fuel that can help to eliminate deposits. Leaking valves can cause poping noise, backfire etc. Easy fix is to try using products mentiond above then new plugs and add several gallons of premium fuel to increase the octane level. If the engine does not run however suspect old fuel or water in fuel bowel. Try spraying carb cleaner into carb little at a time to keep running. If the engine runs with carb cleaner, suspect fuel/carb/pump problem. Good luck

Hi.

If fuel pressure is low and you have already replaced the fuel pump, then the problem is usually the fuel pressure regulator. The pressure regulator is in same assembly with fuel filter. The assembly is located to the fuel tank, bolted to the truck's frame. The pressure is tested connecting a gauge like this : Set Sealey VSE952 to the port on the fuel rail. The pressure on Grand Cherokee must be around 49 psi plus or minus 5 psi. If engine runs but pressure is below 44.2 psi , check for a blockage in fuel supply line between fuel rail and fuel pump module (e.g.kinked line). If the line is not blocked, replace fuel pressure regulator and filter. Test pressure with and without fuel cap on.

Another test to be done is reading pressure, then shutting the engine off with the gauge connected. If pressure goes down too quick, then the regulator is defective. After 5 minutes the pressure should not go below 24 psi. If it does replace the regulator.

If regulator is OK check for leaks at the injectors that can cause fuel pressure drops.To check for injectors leakage clamp off the rubber hose of the pressure gauge tool between fuel rail and the port. If pressure staysr above 24 psi and before was dropping, then a fuel injector or the fuel rail is leaking.

Below a diagram representing the fuel rail and test port. The engines from same years like your six cylinder have the port and rail in the same position.

It doesn't want to start when its sat for over 5 hours. But if I turn the key to the on position 4 or 5 times to run the fuel pump it will start. What could cause this problem? Thanks steve


Most likely fuel pressure regulator or injectors under intake plenum leaking fuel. Remove intake plenum look for washed down intake. It will visibly be clean & no carbon build-up. Energize fuel rail. With plenum off, reattach fuel line. Turn key to run. Watch for fuel leaking in back (fuel pressure regulator) or out nylon lines (fuel injectors). Very common problem.

I ran out of gas in a 1997 Chevy Blazer, put gas in, but still won't start.


The fuel filter may be to dirty to let the gas flow through and will need to be replaced, or most common when you run out of gas is the fuel pump will burn it self out. The fuel in the tank will keep the fuel pump cooled and will keep it from burning out, if you ran it out of gas. The pump may have burn out and will need to be replaced. Check the fuse first and hope the fuse blown due to the extra amp drown from the pump running without fuel. If the fuse is good, then check to see if you can hear the fuel pump start up when you turn the ignition key to the run position. Note the fuel pump will only energize the fuel line for 5 seconds, so you need to listen for the pump to turn on right away. The other thing too, is you can check the fuel pressure at the shredder valve, there should be 62 to 65 PSI when energizing the fuel line and will drop around 5 PSI when the engine is running. Make sure you do not try to start the engine by pouring gas down the throttle body, it been know for the gas to catch fire in the intake manifold and burn up the fuel injector system which is very costly. Start with the simple and check the fuses and fuel pump, then replace the fuel filter. At worst, your going to have to replace the fuel pump by dropping the gas tank and don't forget to replace the wire harness from the fuel pump to the frame. Good luck and hope this helps, keep me posted. Be glad to know you got your Blazer running again soon.

Fuel pump bracking up bit found in filter


the fuel pump in the tank are well known for breaking up, if the filter keeps the fine metal filings out of the HP pump all you need is a new tank pump (they are available after market from motor factors) dont drive it until you have changed pump, fuel filter and really cleaned the casing.
