    I tried to turn mine over a few days ago. nothing. No fuel pump signal, no starter signal. Fuse box has power all over it. IDK what I did wrong. I posted on it in swap. I'm suspecting passkey, and if thats the problem, IDk what to do about it. I don't have original vin to donor car, key...nothing. I'm going back over the wiring in a few weeks. Opening day at the track is in a 2 weeks, drag car gets priority.
    sigpicHow to make High performance Emissions:
    A "true" High flow converter, straight pipe.
    Low/No flow EGR valve, block off plate.
    Carbon canister and purge valve mod, place in large 30 Gallon can, cover, and place curbside, the city will do the rest.
    PCV valve and vent tube, reroute to exhaust to dump where it belongs, on the ground. Or add breathers and let it all free.

      if it is the passkey 2, then it will try to start (crank), but not fire (sometimes it will fire, but die a few seconds later).
