Well first of all, you DO NOT HAVE A CARB, so pumping pedals and such will not do anything but eliminate any chance of the car starting, in any situation. The proper start procedure for any efi car is no pedal to start, and full wide open to clear flood conditions, nothing in between. The flood clear usually results in a start and it revs real high, and usually stalls, then you get to figure out what went wrong. I usually will do flood clears untill it doesnt try to fire, which means your all dried up, then you can go and try a normal NO PEDAL start. You do not have a carb, unless you lied in the rest of your thread. The pumping was quite hard to keep from laughing at in the last video, you got quite a work out making your pcm cry and freak out seeing the tps go all over the place. It was probley jumping between clear flood and 40% throttle aka injectors near full on vs full off randomly, so it really had no chance of starting at all.
The fact that it is firing a bit leads me to think you have seriously fueling problems, or you have 1-2 wires/injectors hooked up total. It would be evident quickly if you have a too much fuel problem, as it would be leaking out the open exhaust.

I feel your pain as I'm recovering from working on the MF wire harness yesterday, I can see how easy it would be to confuse just 2 wires and this whole thing doesn't work then... speaking of which I can't find any reference to what the large amount of pink wires, thats the ones from the stock GTP harness that feed the injectors etc, need to be connected to?
Good luck and he's totally correct above about the pedal, don't touch it you are just adding confusion to the what the PCM is looking at....

I connected all of my engine power to the 2 injector feed wires coming out of the c203. I tried to distribute the load as much as I could to keep any one wires load down. Lucky for us the wiring was overdesigned in the fiero, so you can run serious power through the stock "5 amp" injector feeds.

I love reading these well documented swap threads. It shows a level of organization I wish I had.
But after reading this I think I've determined what the problem is. BLAME THE HELPER !!!! I mean, what is he like 6 or something. How much hands on experience could he have? My son was at least 8 before he could read a schematic and trace and solder wires. He's 12 now and is out in the garage welding up a new exhaust right now. Seriously man, I know you love him and all but he has to go. It's gonna be tough but you gotta' fire him. Sure, he may cry a little at first but hey, that's what makes you stronger on the inside. You may have to start from scratch for a replacement too. Talk to the wife. Buy a nice bottle of wine and see what she's up to tonight. Wink,wink.
One thing about working on your own car that makes it really worthwhile is being able to say I did it myself. Another thing is when your son, or daughter, WANTS to come out to the garage and help you out. To spend time with your family any way you can is precious. My screen name is me working on the car, it's my time. My son is helping so much now I may have to change it to "ourtime".
Wish I could help you with the swap. Did mine a couple of years ago. Got it running right away. Very lucky.
With all of the wiring modifications you made I can't help but think it's a wiring thing. That means tracing wires. Fun,fun,fun. Good luck to you. You're almost there.!!

ok guys I get the hint, no pedal pushing!
anyway, tonight I replaced all the plugs with autolite 103's with .060 gap, got all good plug wires connected, and still doesnt want to turn over. I have about 4 gallons of gas in the tank total, and the rear is sitting somewhat in the air, maybe not enuf gas? it smells like I'm getting gas though.

Honestly, the way it was sputtering, for something simple, check your plug wires to ensure they're going to the right spot. . .

Unless you mounted your fuel pump halfway in the tank, 4 gallons is well more than enough to run the car for 100 miles or so, so thats for sure not the problem.
The next bet is going to be spark, because it really sounded like you were just running on 2-4 cylinders in the video. Or maybe one bank of injectors is not getting power, just time to do basic troubleshooting steps to find things out.
EDIT
After reviewing your thread, I noticed you have a scanner, and you also have a northstar TB. Whoever did your tuning might of well forgot about the maf, and that could possibly be screwing with things so I would just unplog that for now. Hook the scanner up, turn on the key, and see if all your sensors are reading nominally.[This message has been edited by darkhorizon (edited 07-26-2007).]

This weekend i'm going to pull some wiring through a hole in the firewall, I mentioned to FieroFlyer that at one point in the wiring harnass I was pulling 25v through the line with my voltmeter, so i'm assuming a wrongly connected wire that I mistook for a similar color. I am going to try and use a diff set of coils to test also before I start ripping into things, as for the scanner the batterys in the palm died so I have to re-load the software on it.

wow, too many things to mention like, I cut a hole in the firewall and checked alot.... i mean alot of wire and nothing wrong. checked voltage, 11.4...... I had AC on when I measured the other day (25v) duh! went over tons of possible mistakes, checked every ground, swapped stuff in and out. but, in the end I finally figured out the problem... wtf kinda dumba$$ I was...... cyl's go like this:
front /\
531
642
Rear \/
I was putting them
321
654
DUH!!!!!!!!!! SIMPLE MISTAKE OMFG IT RUNS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
