What scanner do you have?
Imho, if you don't know, can't figure out, are too foolishly cheap, to get and use an ~~$40 scanner, then junk the car. Or, bring it to a
dealer ($$$).
Also, fwiw, the mechanics you're taking the car to don't have a
*******ing clue in the world about GM cars, or a number of other makes.
First, note that there are
massive amount of
fakes and cheap sensors/parts out there.
A few things, yea, let's not use a scanner.
Sigh.......
1) It's NOT the computer.
2) Buy the following Crank Position Sensor from
Rockauto
STANDARD MOTOR PRODUCTS PC30 {#10456161, 213151, DR6161}
3) Swear a LOT putting in the PITA sensor.
You must disconnect the battery.
4) If you buy a sensor from anywhere else, then (imho, by definition) you're a fool - since you've been warned before hand about the massive fakes and cheap sensors.
Yes, that is why you MUST buy a CPS directly from RockAuto, or a GM part from a real walk in GM DEALER.
5) It might be the ignition module.
Again, there are a TON of cheap cr*p alternatives, and a TON of fakes.
Fwiw, get it DIRECTLY from a real DEALER that you walk into, or get
From RockAuto: STANDARD MOTOR PRODUCTS LX364
Rock Auto is one of the best places that avoids fakes.
Standard Motor Products are *top quailty*.
I do not benefit in any way at all by recommending rockauto.
In fact, I used to recommend Amazon for car parts. But, many people are to foolish to know if something is being sold by Amazon directly, or a reseller. Sigh...
And, I've "heard", a few times, that Amazon
may have directly sold car parts that were fake.
Note that they may have been wrong.
But, *I* have switched (back) to Rockauto for many of my car parts.
Good luck.
