****how can i cut the fuel to the rear rotor?
i want to see if the front one will start the car or not***

I THOUGHT I had answered that in a post above. It works as described.

But, wait. You probably don't have the tools, so.....here's' what you do. Pull the small plug off the ECU. De-pin pin 3C and put some tape around it so it won't short out when the key is to ON or better. You've now disabled the primary injector for the rear rotor.

Or....pull the LEAD and the TRAIL plugs off the rear rotor. Secure that LEAD plug to a piece of wire that will go directly to a ground. Just lay the trail to the side somewhere where it won't arc you or anything else. Now start the car. WEllllll, try to start the car. Now that's not cutting the fuel, but cutting the ignition is the equal in this case.

There's about three or four other ways to disable it without taking the intake off and pulling the injector plug.

 

sorr I missed your post
but thanks for reposting!

 

has anybody had any similar problems with there 7?
Ie: Lack of starting power 0-60...
Car starts and dies out unless you rev it at least once...
Car backfires every so often (not backfires but more pops) ...(think its cause of a break in the gasket between the downpipe and header...)

The car is running fine except for the lack of power issue.
