Hello Lars,

My guess is the Fuel Pressure Regulator. You said you moved it from your parts car, but perhaps it was bad (or moving the part from V8 #1 to V8 #2 caused it to become bad).

When a FPR fails, it can allow fuel to fill up the cylinders ; if you start the motor with the cylinders full of fuel, it will break several teeth off of the flywheel and you will not be able to drive the V8 over 3000rpm because the timing sensor (OT gaber) will not be able to read the missing teeth correctly.

My friend has created a webpage with instructions here:

The only other problem I can think of is one (or more) fuel injectors.

Good luck!

Regards,
