my car= no start after the swap. help

[sportinct26]

well if you dont know im using a 91 turbo/5-speed harness but my 89 auto/ n/a isnt accepting it lol... (after my N/A to Turbo and auto to 5-speed convcertion.)

so i decided to rewire my 91 harness to match the 89 since im broke... no money for an 89 harness.

anyways so i got her started once and it wouldnt idle i had to be gasing it at all times to keep it alive.

so i stop her and try to figure out what else is up.

and now after double checking and well color matching wires she wont start.

when i crank her it would act like its ganna start. or somtimes it would jerk violently on trying to start up.

and somtimes it even backfires DURING a START ATTEMP.

anyways by what you guys know what wires do you think i missed?

and keep in mind that there are many wires that the shell have that the harness did.

what the hell are you doing? lol. Sorry to hear it won't start. Have you checked the tsrm and EWD here on the forums to make sure you have the right wires mattched up? Sometimes just color matching can screw things up.

You can borrow my 89 turbo harness off my car, or can come and take a look at it man to see how its wired. I am in Hayward and avaialble after 4pm usually.

Harness is on the car.

yeah i looked at that and look at other info to...

um i match most of it lol. (i check the ecu pinouts and all)

the problem is that i cant freacking figure out where the rest of the wires go.(cause turbo harness doesnt have all the other wires.)

well heres what im trying to find now.

the those 3 plug pinouts.

so i know what each wires does and match it up with my harness.

Okay,
B1 is like your main plug. Its the big fat square plug that has the power wires and fuel pump wire etc.

The B2 : I think goes to the dash for all the gauges and some stuff.

I was looking for the pinouts but can't find it.
IF your using a harness from the automatic, or this car you are putting it in was a automatic, you will need to move the Blue/Blk power wire over too I think.
