It is very difficult to bypass because the anti theft system and immobilizer is there to stop exactly what you are trying to do. It is better to fix it rather than finding a way to defeat it.

Where is the fuel pressure sensor located? The sensor is part of the fuel pump assembly and is mounted on top of the tank or inside the tank. It's part of the evaporative emissions system (commonly referred to as "EVAP") and reads pressure in the fuel system to detect evaporative leaks, such as a loose or faulty gas cap.

1. Connect the distributor's B+ (battery) terminal to a switched 12-volt source, such as the ignition switch.

2. Connect the distributor's tach terminal to the tachometer signal wire, if you have a tachometer.

3. Connect the distributor's ground wire to a good engine ground.

4. Connect the distributor's #1 spark plug wire to the #1 spark plug on the engine. The #1 spark plug is usually located on the driver's side front cylinder.

5. Connect the remaining spark plug wires in firing order sequence to the distributor cap terminals. The firing order for a Buick 455 engine is 1-8-4-3-6-5-7-2.

6. Install the distributor cap and rotor.

Question edited for a lot more clarity. Question moved to model category. 2 duplicated questions deleted. Just Refresh the page to see it! Lots of ways in the link, but I doubt they work.
