How to bypass passlock on 1999 chevy blazer


The most common repair is to replace the ignition lock cylinder due to broken wires inside the steering column. Most common problems related to the Passlock family involve the Passlock sensor. The sensor is part of the ignition lock cylinder on Passlock I and Passlock II systems. ( Where the key goes ), Good-Day!

I'd use a gage and check proper fuel pressure, key on engine off, 60--66 psi with spider fuel system.

Click on the link for fuel pump relay, you can check the fuse. At the fuel pump, gray wire is voltage, black is ground.

When you turn the key into the ON position before it starts can you hear an electric motor noise winding up? If yes , the fuel pump maybe OK but if the pump pressure is bad...blazer wont start. Pump runs about 300 plus labor. I've done it..It sucks
