fuel injector fuse blown

[66brain]

Help, son's 1996 escort keeps blowing fuel injector fuse. Starts up with new one installed but seems to blow when he puts it in reverse. Any help would be great!

Check the back up light switch and wires that are on the side of the transmission for a short.

What type of transmission, Auto or Manual?

It's auto tranny. I thought about that wiring but didn't think they would be fused in same circuit.Stranger things happen though..?

It's possible a cross short between the two circuits exists. I do not see a common circuit between the two.
The Gear Shift Neutral Switch activates the back-up lamp switch in 'R' (reverse). Are the back-up lamps working?
I would make sure the two symptoms are related by removing the fuse (the one that keeps blowing) and connect a test light or voltmeter in it's place to the fuse terminals. Wiggle the wiring around (side
to side) while watching the test light. If the bulb lights or you get a reading on the meter, there is a short to ground in that area. You can also shift into reverse and see if the test light comes on.
