Re: How do you know set the couiter balanceto the crank?...
THE CRANKSHAFT VIBRATION DAMPER CRANKSHAFT THROWS AND FLYWHEEL ALL BALANCE THE CRANKSHAFT.IF CRANKSHAFT OUT OF BALANCE AND VIBRATION GOOD AND THE CRANKSHAFT THRUST BEARING NOT WORN.CRANKSHAFT COULD BE BEND.

PULL THE SPARKPLUG OUT OF THE #1 CYLINDER ROTATE ENGINE OVER TO FIND TOP DEAD CENTER ON COMPRESSION STROKE REMOVE DIST. CAP AND SEE WHERE THE ROTOR IS POINTING AND ADJUST SO THE #1 WIRE IS LINED UP WITH IT
Trouble Code 42 indicates that there may be a malfunction in the
Electronic Spark Timing (EST) system. During cranking, the timing is
controlled by the ignition module and the ECM grounds the EST line. It
expects to see no activity on this line at this time. When the ECM
enters EST mode, it applies +5 volts to the BYPASS line and expects to
see voltage variations on the EST line. Reasons for the ECM to set Code 42: 1. System in BYPASS mode (i.e. EST line supposedly grounded) but activity sensed on EST line 2. System in EST mode (i.e. BYPASS line driven with +5 volts) but no activity seen on the EST line
Possible causes include: 1. BYPASS line is open or grounded 2. EST line is open or grounded 3. Poor connections between ignition module and ECM 4. Poor routing of EST harness and/or poor quality ignition wires (EMI induced electrical noise 5. Faulty or incorrect ignition module 6. Faulty ECM 7. Faulty Pick Up Coil 8. Faulty Ignition Control Module
9. Faulty Crank Sensor or the Crank Sensor magnet probe could be cracked
first you need a timing lite second when you start it you hold the timing lite at the crank there are degree marks near the crank you should clean the crank and there is a mark on it remark it with white chaulk thats how you set timing
The dealership can bypass the security chip no problem. The chip is a resistor and they use a resistor of the same value at the bottom of the steering column to bypass. resistors and soldering are required.
