Does your car have trouble starting? Trouble idling? Lose the RPM Tach? This may be the reason why.
The crank sensor plays a very important part in the well being of your vehicle.
"The actual threads for the harmonic balancer are: 6mm X 1.0 by 70,80,or 90mm long. Also it helps to use hardened flat washers too."
How to replace a crankshaft sensor on a grand prix gtp
This video is dedicated for the GTP owners that need to do the same
crankshaft replacement procedure as I am demonstrating. I hope this video
helps anyone out there that needs to tackle such a job and the video also
shows that it can all be done with simple tools which in turn will save you
time and money.
Crank Position Sensor Replacement - Stalling 3800 3.8 Engine
If you have a vehicle with the GM 3800 Engine which stalls randomly and may
not always restart, then you likely have a bad crankshaft position sensor.
If your vehicle runs perfectly but the tachometer sometimes registers
incorrectly then you should replace this sensor ASAP before it leaves you

Crank Sensor Quick-Fix
There are two types of crank sensors, and two types of tests, the 2 and 3
wire sensors. Here are the flash points for the crank sensor testing.
1) The 2 wire crank sensor generates a voltage, and is quick tested with a
2) To test the two wire sensor, disconnect the crank sensor, ignition key
on, hook the test light to battery power, and tap at each crank sensor
terminal repeatedly. A spark click and injector pulse should be seen.
3) The 3 wire sensor has its own circuit, with 5 to 8 volt power, ground,
and signal wires. Identify the signal wire using volt meter or diagram.
4) Take the test light and connect to battery ground. With key on,
disconnect crank sensor, and repeatedly tap on the signal wire. You should
hear a spark click and injector noid pulse.
These are to test the ECM crank sensor circuit response. On both tests, you
should see a spark click and injector pulse. Crank sensor is the main input
to the ECM. If ECM working, then the crank is the only other issue. There
are other ways to test, but involve an oscilloscope and more complex. This
concludes the cranks sensor Quick-Fix.

Once again, this video covers why we need to learn proper troubleshooting
techniques and to not be so reliant on manufacturer "flow charts". If you
think your engine computer is bad, you must watch this video! Are there
more tests that can be done to prove a computer is bad? What else should
you check before computer replacement?

No Crank, No Start Diagnosis - EricTheCarGuy

Whenever you have a no start condition when attempting to start your
vehicle it's important to make the distinction between "no crank, no start"
and "crank, no start" situations as they are treated differently. This
video covers what I do when confronted with a 'no crank, no start'
situation and in this case it's a worst case scenario so be sure to watch
till the end.

Engine Won't Start - No Crank Diagnosis (Troubleshooting Starting System Issues)
In this video I show you how to diagnose a no crank condition on a 1997
Honda Accord but the techniques shown here can be used on any vehicle.
A no crank means when the ignition switch is turned to the start position
the starter doesn't crank the engine.
To troubleshoot this issue I cover battery testing with a load tester,
solenoid trigger wire testing, and voltage drop testing with a multimeter
on the power and ground side of the starter.
I also cover how a relay works, how the starter solenoid works, and explain
what the neutral safety switch is and how it's incorporated into different
start circuit designs.

Pontiac won't stay running!
My 1995 pontiac bonneville with 90xxx in a 3.8l engine won't stay running,
when I rev the engine it stumbles and stalls. Won't start right after have
to remove key and then it will start. What could this problem be, I'm
thinking fouled plugs?
GM Pass Key II Malfunctions: Bypassing V.A.T.S System
Your car won't start? SECURITY light steady lit or flashing? More then
likely it is the Vehicle Anti Theft System (V.A.T.S) at fault. Over time
the resister pellet imbedded in your car key wears out from years of
inserting and removing from the ignition lock cylinder. Here is a cheap way
to bypass it, so you can get back on the road.
