87 f250 5.0 flooding issues?????

[shawnw1212]

OK I have a 87 f250 5.0 5 speed 4x4.
I'm flooding out on 1 4 5 and 8.
Now I have done the following.
Replaced the timing gears and chain, fuel regulator, 8 new injectors, new main computer, plugs and wires, distributor, cap and button. And only 2458 flood out plenty of spark good compression.

Here is were it gets tricky follow me guys in order for the truck to run we had to take one of the negative injector wires splice it and ground it out to the block. Once we done that the fuel pump and injectors work. But once u disconnect the ground u loose power to injectors and FUEL PUMP. Weird. But iv checked all my ground points cleaned them all went threw my Chilton manual replaced fuses replaced relays nothing is working the truck runs and will drive but just the injectors are staying wide open they won't pulse like the others. Can somebody please help me ??????? Iv also went as far as thinking maby the ground for the fuel pump is bad so I ground it by itself and still nothing the only way for fuel pump to work is to ground with injector wire.

Boy, that`s a conundrum. About the only help I can offer is to get real up close and personal with the wiring harness at the ecm connector, to the engine, and what not. Sorry. There is a little green wire somewhere. And not insulation green.
