dpfi->mpfi wiring problems

[ssl2k]

The car is a 90 DX automatic and I did the dpfi to mpfi swap and did the auto to manual conversion, the mtoor is a dohc zc...this was a 100% working and running motor and just swapped it inot this other car...

well the #3 cylinder that you use the red wire from the #2 injector(from the orignal dpfi injector..) for the signal wire seems to just be constantly spraying and not firing. Checked spark and it is sparking.

No CELs. The exhaust port is wet with gas and we have spark on that cylinder

any ideas?

what kinda shape is the plug in the wire the dissy?

 

[ssl2k]

square

the motor actually would fire up and run but only on 3 cylinders...

it is a 5 wire plug (the dohc zc and the dpfi plug lined right up)

yes

ok have you started it then tried pulling plug by plug to check for a drop?
also check the injector it may be stuck open and check the voltage

Move the injector to another cylinder, and see if the other cylinder is affected or if it is just the #3.
