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.

Car will shut down at random times. There is no pattern to it either. It will shut down at a traffic light, on the highway, or on city streets. I have power everywhere else: lights, radio, and everything...


It could be an electrical problem or a fuel problem somewhere, but I suspect the CPS (crankshaft position sensor) is going bad. When this starts going out, the car will shut off at anytime, but it will sometimes start right back up and sometimes a couple of hours. But I will say, if this is the problem it will leave you stranded. Good Luck.

Shuts down after 1/2 hour drive


The EGR system does this to engine after running a short time. Have it checked out. The valve, solenoid, & the relay for it can all cause this problem

Well, something idoesnt like to be warm in it, ive seen this caused by multiple things, but most commonly its the starter going out it gets warm from the engine running and the brushes expand and short, cools off brushes shrink and VOla Vrooom Vroom!
