2001 Chevrolet Tracker Q&A

2001 Chevrolet Tracker Question: WHY DOES MY TRACKER KEEP TURNING OFF BUT STARTS AFTER IT COOLS DOWN.

I ALREADY CHANGED THE FUEL PUMP,FUEL FILTER,CRANK SENOR AND SPARK PLUGS -
Answer 1
Fuel is a good guess; Is there a service indicator showing for information ? If not it's back to the basics. What is not working at the time of the failure, no spark, injection pulse, fuel pressure? The fault has to be found, then trace the error back to what controls that function. You've already spent money to address to problem, seek a person that can help you trace the malfunction, with the right tools/equip, back to the root of the problem. -

I JUST FOUND OUT THAT THERE IS NO SPARK WHEN I TRIED TO TURN ON TRUCK ...SO WHAT OTHER SENSOR COULD CUT THE CURRENT GOING TO THE SPARK PLUGS -
Answer 2
Possible ; crankshaft angle sensor on the rear of the cyl. head, looks simular to a distributor without a cap. How about the "indicator" already ask about in #1 answer? Light on in dash while it's running? Good scanner is a must! Even IF no light is on. -
