yes i do plan on painting it soon, basically i want to get most of the bugs worked out of the swap before i tear it back down to paint it.

this damn spark issue is kicking my butt!! and now my fuel pump isnt turning on! idk what to do. it sputtered for about 3 seconds only once, now ive got nothing. idk what to do. im losing faith in this car by the second. i am to the point where i will pay someone to come over here and figgure it out for me!

well i have a update for everyone. it still wont start. im starting to get really annoyed. here is what i know.
1. i have a good ignitor.
2. the green light is on inside the ecu (but isnt when cranking, might be an issue)
3. i have power to both my coil, and ignitor, and i belive my ecu is pulsing to the ignitor.


so im at a loss here. i dont know what to do. or where to look. besides going megasquirt, i dont know what to do. but i do have some more pictures for everyone.

and just for some giggles, my lil girl, Chloe.


ok well ill go back to basics. i know the motor is good, i drove the parts car around the block with no brakes lol!! im using all the zxt parts, injectors, afm, ecu, i havent put in the turbo fuel pump yet, but im not sure if its going to be needed.

last night i wired in my own fuel pump relay, now i get the 5second prime, and as soon as i touch the key to turn it over, the pump kicks on. still not sure on the amount of psi.

i can hear the injectors pulsing.. or clicking rather.

the green light comes on inside the ecu, does not seem to be there while cranking, as i stated earlier, this might be an issue.

im not sure if my CAS is sending a signal to my ecu so the ecu can send a signal to the ignitor.

i really believe my issue is spark related. is there a way to test the CAS. mine is a 81, so its down by the crank
