3.4 starts then dies

jpmountainboy · 10-04-2009, 08:07 PM

hello,

I just finished my long awaited 3.4 swap today...but. I put a 99 taco in a 94 pickup MT.

The problem is it starts GREAT, runs SMOOTH for under 10 seconds, then cuts out. . Then it will just start right back up and do the same thing. Almost like the fuel pump works on start then cuts out.

I figure its something to do with fuel control but thought I had those hooked up logically.

the only thing I have not been sure about with the wiring is there was no BATT wire going to the 99 ecu from the spliced ih1 to Ik2. My 99 ecu seems to have only e6 e7 e8 plugs, but all the diagrams I can find on the 99 say there is an e5 with a B-Y BATT wire to ECU...but I just dont have it. so on the old there was a batt wire IH1 pin10 B-G but there is nowhere to splice it into the 99 ECU as I dont have that plug (but do have the 3 e6 e7 e8)plugs, and the only other B-Y wire to the ECU is from the igniter, so I just dont know where to go form here. There is one blank bank on my ecu, but I thought that was for diagnostics.

Any help would be greatly appreciated.

vaccum seems good...

FIXED!!!

double checked fuel control wires and found a mix up. I LOVE being colorblind.

still have some literal loose ends to tie up but Im feeling pretty good about maybe even being able to drive my truck again after a year of building.
