crank sensor

What is your question?

pickup keeps stalling try to start all it will do is turn over, let sit a little while and it will start, might do this 3 or 4 times and will run all day as long as you dont shut it off for a little while then it dose it again, when its doing this the tach will jump up and down when the key is on dealer put a new ecm lots of money no help,[ps how do you get a wrench on that bolt on the crank sensor
