Ok Guys.....  This is where I'm at. I bought a 92 tracker from a guy who bought it from another guy with the head removed because it had a blown head gasket. It supposedly ran when parked and dissembled. Now the Guy I bought it from put the motor back together with a new Head gasket etc and couldn't get it to start, subsequently he lost interest and sold it to me. First thing i checked was the timing and found the distributor was 180' off. squirt some gas into the tbi and it will fire and run until it runs out. So I check and no fuel pressure. New pump, strainer, filter, tank (it had been sitting for four years) and fuel regulator and I have good fuel  pressure. still no start and no fuel coming out of injector. I swap injectors with another Track and it works fine. I have power to the injection circuit at the fuse box, I swapped the ecu boxes on the fire wall, swapped Distributors and coils, swapped relays on passenger side on fender, found a couple more to swap under the dash as well. Everything I have swapped has worked just fine in my other Tracker. It looks like there are a couple more relays or something mounted above the fuse panel under the dash and will swap those when I get time. Am I missing anything that could be related to the head removal and reassembly? When I turn the key on the fuel pump will run for a few seconds like it supposed to and shuts off. Anyway, let me know if you have any idea what is going on here and yes, I will send who knows the problem and or corrective steps to take to solve it 25.00...... TIA!   This Tacker has me beat down and humbled.....

Was the ECU you swapped from the same year and transmission type?

Did you crack the old ECU and look at the board? I would bet the Capacitors
leaked and corroded the traces that power the injector

I swapped out the ecu's they both work and both are same year and both are automatics.

does the fuel pump run when you cycle the key? if not, start at the fuse and chase it back to the tank. common things to look for are the fuel pump relay and corroded wires behind the driver tail light.

If I had to guess - there are probably some ground wires that ground the ECU to the intake manifold, and those weren't reconnected.

Also check the green/black wires at Brake Master cylinder (for one or a group not grounded), these grounds do affect the main power relay and fuel injection.  Also double check fuses, the larger ones by battery and small ones under dash. 

OK, ECU is good and confirmed, is the injector harness plugged in to the main harness? or verify
the pins are all making contact?

I'm referring to the big plug not the 2 pin that's right at the injector

Yes, fuel pump works and I have good pressure.

"If I had to guess - there are probably some ground wires that ground the ECU to the intake manifold, and those weren't reconnected."

The cluster of grounds is conected, I swapped out the large fuses with my other Track and all is well. I checked the connectors and followed wires all the way back to under the dash. looks like I'll have to get to the relays under the dash above the fuse block. I'm not looking foreword to it as I had back surgery 6 weeks ago...... So, ya.... Everything I have been doing is pretty much in slow motion. Thanks for the input, I was really hoping I overlooked the obvious somewhere. I guess I need to get to the wires coming from the injector and the distributor under the dash and check continuity. So much for a quick easy project, I'm just happy it is my time working on this...... Looks like I work pretty cheap!

Check the noise suppressor on the bulkhead. The brown wire is the signal to the tach and is also used by the ECU to confirm that its sparking, if it doesn't see a spark it will kill the fuel.

  Alright, so who got paid? anyone figure this out?

Have you actually hooked a gauge up to test the fuel pressure (should be up around 40psi)?  If so and it checks out within spec, I'd say you aren't getting an injector firing pulse.
Have you got old, crappy gas in the tank and lines.  Or did you clean all the old out and put new in?

Nobody has been paid yet, Yes it has fresh gas, new delphi fuel pump, new fuel strainer, new fuel filter,fuel lines were cleaned out before reconnecting them, swapped fuel pressure regulator with my other geo, swapped ecu's, swapped distributors and coils including noise suppressor and swapped injector and TPI. Yes the grounds are all connected and fuses have been checked and I have power to the fuse box for the fuel injection. The fuel pump runs for the same amount of time as my other geo's when I turn the key on, i have not put a gauge on the fuel line for actual pressure but it acts just the same as my other geo when disconnecting the fuel line or taking out the injector. So, Yes, as near as I can tell I am not getting a signal to the injector because no gas will come out and it is not opening. I have not had time to get under the dash or try to test for a signal at the injector yet as I have been busy taking care of other things for the last couple weeks instead of wasting more time on this thing and not getting anything done.

Thanks for the Ideas, anymore? Keep them coming. I will Pay the bounty and post what it was when I get er going! Thanks again!

Check the continuity of both the injector to the computer wires, sounds like
you have a break or corroded connector in there someplace

 The best to check for injector trigger is a noid light, if you can get your hands on one. If your fuel pump does run when the key is first turned on but stops it sounds like a cam or crank sensor issue. without one signal or the other your fuel pump will not continue to run and fuel injectors will not fire.

Ya, except that year Track/Kick doesn't have those sensors
