It's alive!!!
 

Well, the 93 I swapped a 94 engine in is finally alive! :D
Man, this was a long, painful project. Live and learn.... :(

So if anyone remembers my first post when the starter wouldn't even turn -- (you can find it here) it turned out that my attempt to convert the 93 to mass air was a failure. While the 93 and 94 harnesses are generally the same less the PCM connectors on the outside, they are really completely different. So sorry 93 guys, I had to learn this the hard way, but you cannot convert to a MAF setup/reflashable PCM "easily". A painless harness will be required, or major modifications to the factory harness.

Anyway, I ended up pulling the 94 harness off the engine yesterday and replacing it with the original 93 harness and ECM. This yielded a "cranking, but not starting" problem. (the post is here)
I pulled one of the wires today and used an old spark plug to test the spark. It was there.
Then, tonight, I pulled the fuel rail and injectors. Guess what? Every single one of them was bad/dead. (the engine was sitting in a garage for a few years)
I swapped the 22 lb/hr, 129K miles injectors from the 93 intake I still had laying around in a corner of the garage and it fired up right away! The starter didn't even finish the first turn and it was already running. I could not beleive it!
Anyway, it seems to be running well. I have lots of stuff to do still, but at least I know the engine is good and my 2 month warranty on it expires on Monday. :D

$hit dude thats a lotta work... and you did all that for another STOCK engine :rolleyes:

Please tell me that the old engine was crap or the new one is modded!

In any case, good job with the engine swap, they are a major pita with our cars.

Yes, the old engine had a cracked rod and I picked up this car really cheap. The new engine isn't modded, but it has really low miles on it, so I'll be using this car as a daily driver for a while then most likely this winter, I'll put a cam in...

Either way, it's a long story but I don't regret it. It was a good learning experience and something to do on the weekends. :D

OK, makes sense now. Nice work, it must be nice to have a low mileage engine again....

congrats, nothin better the the feelin of a job well done :)

cant wait to hear my turd rumble again :(



so you ended up leaving it speed density ?

Yep, it's SD for now... at least until I can find some 93 wiring diagrams. ;)

hum, have fun it didnt seem worth the time to me. Besides you already have the capabilities to burn new chips so why add a maf for a restriction ;)
