I have a 86 Toyota 4Runner, it will not stay running. It will start right away and run for about 5 seconds and then die and won't start unless I leave it alone for an hour or so. It cranks and wil


Good explanation of symptoms.Thank you.




No assumptions.
Diagnose problem.
Pinch off the fuel return line.
Check fuel pressure--I don't wanna!PITA!
The fuel pump won't run if the fuel filter is plugged up.
Toyota's have a gas tank drain plug!!!!!!!!!
My '84 takes a 3/8 " ratchet. Cool.

There may be a fuel pump relay that is toast,but I suspect the filter,off hand.
A plugged filter will overwork the pump and cause the engine to run rich.

I have A 95 Astro that has A new Fuel Pump and Filter that was replaced 3 months ago.. I replaced the brake fuse and it will start run ,but it died so as I give it any gas.. Is this the fuel reg??


Check your fuel pressure at idle and under a load, if there is a fluxuation greater than 2lbs you should check for a bad fuel filter and then the pump return line.

I have a 1993 gmc 2500 van with a 4.3 v 6 engine stalls will not start. get no fuel at throttle body inj. if I add fuel to throttle body van will start and run as long as I give it gas . when allowed to...


You must have a leak or one of the lines are clogged. The reason it stays running when your on the gas is because it keeps the fuel pressure up. Then when it shuts off it loses all pressure in the line and the pump cant handle the initial start with the leak in the line.

CHECK FUEL PUMP FUSE AND RELAY.IF BOTH GOOD LISTEN FOR FUEL PUMP RUNNING IN GAS TANK WHEN YOU TURN ON THE IGNITION SWITCH.YOU HEAR NO SOUND.SCAN VAN FIRST FOR PCM FAULTS SINCE IT CONTROLS FUEL PUMP IF PCM GOOD.FUEL PUMP IS BAD.IF FUEL PUMP RUNNING REPLACE FUEL FILTER.

Engine dies when running. Intermittently dies while running no sputtering or other warning, all of a sudden the engine is off. Mostly happens at lower rpm's. Starts right back up after putting it in park.


first thing to replace and cheapest would be the fuel filter ,if that doesn't fix the problem , it may be the fuel pump . GM fuel pumps are in the gas tank, and they have a built in thermo fuse . when fuel pumps get old 60000 miles or so..the motor in fuel pump starts running to hot and the thermo fuse kills the power till it cools down then it will run till it gets hot again note the cool down time keeps getting longer and longer

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.

Jim; have you confirm the fuel pum[ is working? If it is, you should get something out of the fuel rail. Sadly. Pump is a dealer recommended repair cause the pump is more than likely in the fuel tank. Thry should changre you filter at the same time.
