I have a post on the engine swap thread and I was refered to here. I started out with a 90 sd v6 and now I got an 88 maf 350 tpi. I'm having some wiring issues. I got it to crank but I have no fuel and no spark. I have an 87 harness and ecu. Please help.

 

Any guys that read this please give us some info. If you need more information on what's going on say so.

 

ok so ive pulled up a bunch of diagrams and it seems that the 87 v8 bulk connector does NOT connect to the 90 v6 bulk connector. IT seems i need to redo alot of the wiring. Does anyone have a write up on how to repin these bulk connectors?! ive tried and cant get the pins to come out, so im assuming im missing something...

 

A 90 had VATS and that might be part of the problem. By pass the vats part under the column with resistors. Just a guess on my part. I would also go with a SD set up with a computer (from a 350 TPI) and wiring. It would probably elimate some of your problem. Your try to run two different systems and the car was orgainallya SD so in my opinion that would make the wiring problems easier to solive. Again just my 2 cents

yea we are also going to look into doing that as well with the VATS. Were also going to run a wire from the sending wire of the fuel pump to the battery. does anyone know which wire is the sending wire?
Were converting to MAF (we already have everything for it, pcm, wiring, sensor for the maf,) and we have no more money to retrack our steps so id like to just continue on with what were doing, thanks for the help tho.

 

You can disable vats in the calibration, but I don't think that's the problem. Any codes?

You might try using a t-bird analog maf if you don't want to wire in all the extra relay hardware for the tpi maf. The t-bird maf doesn't use a burnoff relay so you just hook up the power, signal and wire the 2 grounds together.
