Bought a 1jz swap that was already running in a sc300 the car starts, idles and revs fine in park or N. The second we put it in reverse or any drive gear the car loses injector pulse.

What could be causing this?

 

some one gotta know... i want this car out of my driveway.. I can't figure out the relationship. It will run fine at idle and rev.. as soon as it goes in gear we loose pulse and instantly at that.

for the lfe of me i can't imagie how the 2 could be related

 

Most likely something isn't right with the wiring.
