Engine swap troubleshooting

[pearldrumbum]

Working on a 92 camry, 2.2 auto. Engine was run out of oil so I pulled it out and got a sweet deal on an engine out of a 95 camry to put in it.

I'm using the 92 harness and computer, the only thing I noticed that was different was the 95 egr had a sensor on it that the 92 didn't, so I just put the 92 Egr on it instead.

So I get everything all put back in the car and VROOM starts right up. It's stumbling kind of bad and doesnt rev up with throttle, and the tach isn't showing anything. so I shut it off to realize it's leaking fuel from the fuel filter. I take off the banjo fitting and mess with the gaskets and put it back on. Now it won't start at all (but doesn't seem to be leaking fuel). It'll crank all day but won't fire.

Any idea what this could be? Did the leaking filter have anything to do with the stumbling or was it just a coincidence? Lastly, does anyone know where I can find detailed wiring diagrams from 92 and 95 to see if something could possibly be switched? It seemed to me that both engines had all the same sensors with the one exception of the 95 having an extra sensor on the egr.

If you want the exact electrical diagrams, you probably should subscribe to a two-day pass to Toyota TIS - for $15 you can grab exactly what you need.

ok, so I've deduced that the 95 engine I put in is a california engine because it had 2 O2's on the exhaust manifold (I swapped the exhaust manifolds though because the bottom flange didn't line up with the down pipe).
I'm guessing this has something to do with my problems... I've checked and rechecked all of my wiring connections and vacuum hoses to make sure I haven't absentmindedly left something important unplugged, so it has to be that one or more of the important sensors are wired differently (maybe something in the distributor? this may explain why the tach wasn't working when it did decide to start)

So anyways, with this new revalation... does that make it easier to pinpoint the problem?

Um, '95 non-Cali had an O2 on the E manifold, then a cat immediate below the manifold, then another O2 immediately below the cat. Wrong O2 sensors might make it run like crap, but it shouldn't keep it from running at all. You could always just unplug the O2 sensors for now, and let it use the default fuel map, which should be fine for getting it working.

Tach not working sort of sounds like a crank or camshaft sensor issue...not sure which the 92 ECU used monitoring rpm. Having cam and crank timing getting to the ECU is pretty critical to getting anything at all running.

as far as I can tell, there are no cam or crank position sensors. Those are usually only on cars with distributorless ignition right?
I think I may have been wrong about it being a california motor. According to the haynes, the distributor on a 94-95 california engine is diferent from a 92, but the distributors are the same so I think it might be a non california engine.

Anyways, in case this is getting confusing I'll summarize...
Car: 92 camry 2.2 auto
Engine: 95 2.2
Harness/computer: '92 stock
Problem: Cranks but wont fire. For sure getting spark and fuel, pretty positive the timing is ok, because it managed to start and run once, but haven't gotten it to since.

Any other ideas? This is going to drive me absolutely crazy in T-Minus... 4 hours
