ok well i have 2 grounds on the coilpack connector, 3 if you count the trigger with the key on!!?

and the front cylinders have fuel on the plugs now...the rear plugs are dry...the heavy red wire to the injector plug is ground.

edit: there were 6-7 codes---all for the TVG circuits---and a fuel temp sensor imput low---

new fuel lines mocked up. Final install will be more neat and bolted down.

thanks!

ok so i now have power at all 4 coils, but only one coil is firing---i am looking for the ecu pins for the coil signals so i can check the wires for continuity...it is frustrating at best, but i think once i get spark, she's going to fire up.

Do you have a flex pipe before that bracket in front of the muffler?

update:

so everything was plugged in to my knowledge---and i'm only getting one coil firing---(main relay is triggered/no power to coil trigger wires) turn main relay off and i have power to the triggers ---does this mean the ecu is broke since only one is working even tho they all get power??

Maybe the coils are dead?

I don't think I would trust that to provide enough flexibility in an exhaust system.

It seems pretty risky to me too. I'm not so sure it would allow any flex once its torqued down.

i have been lurking, and i had to say i eagerly await your completion. or seeing it driveable, since projects are never done!

P.S. those summit fuel cells suck! they deteriorate rapidly, but for the price i didn't pass it up. i now regret it afterwards. i also removed the foam after a bit of use. it seems to hold the gas more than help with anti-slosh imo.
