cascade of problems has taken its toll, now how do I remedy it?
First off I'd like to say I know what I did was stupid and if I could have done things different I would have but I had no choice but to do what I did. I did the dpfi to mpfi over the weekend (now I wish I hadn't) but at any rate it has fried my catalitic converter.
Cascade of events that lead to my problem:
1. we did the conversion and weren't able to get all the bugs fixed before the shop closed down. With the car running totaly rich, so rich clouds of gas came from the back, I had to drive it about 300yds down the road to an abandoned warehouse. where it sat over night.
2. Next day working at the warehouse I was able to straighten out all the error codes. I had a few wires crossed and was missing a pin on the ecu harness. Never do work in a dimly lit place, that is probley mistake number 1.
3. with the error codes now straighted out I had to drive it back to school, several miles, still with improper timing and probley still runing rich but at least it was clouds this time. On the way to school it starts smokeing something awlful, it didn't smell like anyting i've ever smelled before. We make it to school still smokeing and shut the car off right away. We hear something that sounds like water running or dripping. Look under the car and the cat is glowing red, bright bright red though the heat sheild.
Come to find out the FPR had no O ring in it, which was allowing fuel to excape past the FPR. I would imagine that this would cause a lean burn, but it must have been making it rich to fry the cat.
I feel the cat is now one solid mass of restriction because of the melt down. I'm going to gut it for now and see what happens. What else do I need to do to make sure my car isn't going to blow up wile I'm driving it? It hasn't thrown any error codes but I'm worried about it. I know the timing is off but I can't find any marking on the pulley to align it to! Any ideas?

You do have marks, they are probably just hard to read on the crank pulley, they are in the inner rib, turn the car off and crank the engine over by hand until you can find them, clean them off so you can see them, then get a good timing light and set it to 18. As far as the cat goes, dont worry about it.. I've seen lots of people do that. The cat was probably all carbon infested and ready to go anyways. Gut the ****** out or put a test pipe in, the car will probably run way better.
good luck

when I did my b16a swap I managed to get all the dpfi-->mpfi ---- right and just mess up other stuff (not hooking up temp gauge and blowing up radiator). I have a test pipe in because my header didn't reach the cat.

also running lean makes it hotter. So this tells me, along with the glowing CAT, that the Oring u were missing let all the fuel pressure **** away back into the tank casuing you to run lean. fix that oring.

it sounds like you should be fine, i had a busted injector o ring and had the same problem, and yes if your cat was glowing red, you were way lean not rich! just get your timing straight and you should be fine.

Re:cascade of problems has taken its toll, now how do I remedy it?
The saga continues. I worked on it a bit this morning with no good results. I didnt get to gut the cat but I was able to unbolt it from the header. I finally found the timing marks but they are so small you can't hardly see them with the timing light. I started the car, still running like *** and move the timing to full retard and it still couldn't get the marks to line up. I switched distro's for one that i got at advanced and now its giving me a Ign. Output error (code 15)? What would cause the car all the sudden to have an error code with a brand new rebuilt part?
