Chevrolet Repair: Freak Problem: 1998 Chevy S-10 130,000 miles, crank sensor, air gap

Freak Problem: 1998 Chevy S-10 130,000 miles

My truck just received a new altenator, fuel pump, fuel pump harness wires all within the past few months. I was returning home after work one night and the battery light came on and the whole truck just died. After about 5 tries it started up again and I made it about 2 miles down the road before the whole thing happened again; after a few tries it started and when I parked it that night it wouldn't start anymore. All gauges (including the battery) showed normal readings and all fluids in the truck are fine.

I put it on a computer which indicated it was a bad crank sensor; I tried a new crank sensor, but that didn't fix it.

Any idea what could be causing these problems?

Thanks for the help.

Answer
aRE YOU sure THAT THE NEW CRANK SENSOR IS WORKING ?. jUST BECAUSE IT'S new DOES not GUARANTEE THAT IT IS WORKING. Did you TEST it ?.

Some crank sensors MUST be adjusted to a specific setting and some are NOT adjustable. If yours IS adjustable the AIR GAP MUST be set correctly. You can compare it to an old style set of distributor points in a distributor. If they are not gapped EXACTLY right the truck won't start and or will run terrible.


Did you check to see if you have a loss of ignition to the spark plugs ?.

Did you check to make sure that you have proper fuel pressure and fuel volume. ?. just because the pump is new does NOT GUARANTEE that it has not already failed and or a wire came loose which you replaced.

Just because you got a crank sensor CODE does not indicate that the sensor is faulty. It could be the sensor connector wiring or the wiring from the sensor to the ignition module or the module itself.


let me know what you find and if you resolve your problem.
