I've had my 4 Runner since 1995. Its a 1990 model, with v6. I have an issue everyday. 4 Runner runs great AFTER its warmed up after 15 min, its a manual transmission, V6 engine. After driving awhile, and I shut off vehicle in a parking lot, I go into a store. I come out in 5-15 minutes, and try and start. I turn key, revs up and dies. Turn key again, revs up and dies. No foot on the pedal. Turn key again, it starts and stays running. Sometimes takes 4 or 5 starts. If I did apply gas, then it really won't start.
When a cold engine, starts fine every single time. But within 5 minutes while I'm driving it may stall at a stop light unexpededly. Scares the crap out of me.
When I give a little gas and let out clutch, it stalls. But then it starts fine usually. It acts like a fuel starvation problem as sometimes I can avoid the stall by gassing it. Usually when engine is warm, and after I've left a parking lot it will stall within 5 min even when I'm in 5th gear heading down the road at 40mph. Then I coast into a parking lot, then it starts right up.
After its warmed up, & while driving freeways & around town, no issues after it has been running 15min+. Fuel filter has been changed, fuel pump changed, fuel pressure regulator changed, fuel pump relay changed, Mass Airflow Unit changed. Still not fixed. Is this a cold start circuit issue? If someone has some ideas, I would really appreciate it. The seasoned mechanics scratch their heads, and labor rate is like $100 hr. here. I would really appreciate the advice, I'm a volunteer dad and I have to take some boy scouts camping and really need this vehicle. I do have the Orange Toyota Shop Manuals I bought in 1996. So if anyone has advice, I have the diagrams to look at. Not sure if engine check codes would help....Tony
