I'd say your ECU module has gone bad. I highly recommend the guy I found on eBay that was rebuilding the modules exchange , he installs a performance chip in the modules and your Tracker will have 20% more power! You can probably buy the chip and install it yourself if you know a little about electronics, ground yourself when installing the chip!

I have a 1992 gmc jimmy will turn over and getting fuel and getting fire but will not crank. whats the problem? I have replaced the fuel pump, fuel relay, injectors,pressure regulator, dist.cap....

did you replace spark wire 1 by one,? if not bingo, you layed them down wrong.... (did car just die, by self or after a tune up?)
4.3L V6?

please stop throwing parts, you rich>? (60k tune up excepted always)
the EFI engines will not put out fuel if spark is dead.
what does getting fuel mean?
1: injectors squirt?
2: the cracked open rail plug dribbles?
3;spark plug tips wet,
4: black smoke out tail. what/?
it's a no start, cranks perfect car, you keep saying no crank.
A car that can not crank and can never be started unless push started,
with a M/T STICK gear box.
seems to me its flooding. , no>? soaking wet spark plug tips?
when EFI , floods a car , WOT cranking clears the flood.
Wide open throttle, its in you operator guide, RTM.
so if flooding, what i do us cut power to the fuel pump
the crank it dry. (black smoke out the tail, and then sputters an runs and stalls)
then, i try only test fuel. that is right,, no fuel pump power.
and make sure my engines sounds perfect with just test fuel.
if that is all true runs on test fuel,
then the problem is FUELING ONLY>
all in the span of 10mins work.

see scotty do that here.

this is a very old car is this a TBI car, a very old single injector
engines or MPI , multipoint injection.

read the wiki, see all those engines.
and EFI
which one do you have.
yours is LB4 or L35 engine?
APPLES and ORANGE different. ! TBI/ MPI.

3: remove rail,
4: unplug injector connector ,under suspicion. (can be done first)
5: pull out injector from its cushion.

you could RTM and heed all warings... many

1991 tracker with a 1.6. has a miss when running. when up to speed and holding at a steady speed miss gets worse. drove for about an hour and started cutting out very bad lost speed,power. converter red...

Do a compression test of the engine. See if your valves are seating properly is what you'd be looking for in checking for low compression. It could be causing the miss. When you changed plugs, did any one plug stand out as being different in color or texture at its base? The constant miss might put black sooty deposits on the spark plug. Course you'd have to remember which cylinder that plug came from to help you locate the miss. I'm assuming you have throttle body injection?

Does a geo tracker have a hot and ground injecter wire

no. the TBI works unique.
it has a driven ground and driven hot,
unlike any 1992 tracker with MPI engine 4 injectors.

if the NOID lamp test fails. the ECU is bad if the fuses IG-coil are good , "FI"f fuse, good, and no DTC errors?
and ground to the TPS is not cut.

My neibor has a 94 intrepid that the trans was said to have gone out in and has been sitting for about three years. I had to change the ignition lock cylinder because he lost the keys. Then I put a battery...

fuel at the rail dosnt exactly mean your getting fuel to your injectors, if you dont have a book to the car, call a dealer and ask what voltage you should get for injector plugs and check that. also dont assume its getting enough fuil to the rail, double chech fuel pressure, be sure it follows required specs. if none of this helps injectors are probly done, replace them.

I have a 92 geo tracker but will not start, i've chance spark plugs, wires, distributor cap and rotor, ignition pack, altenator, and the carburator throttle body, why wont it start?

If you look in the engine compartment and on top of the engine you will see a fuel rail which is connected to the fuel injectors and at the end of the rail closest to the front of the engine you will see a bolt head I think about 5/8 or so wrench. Take it loose and turn the ignition key on and off to see if there is any fuel coming from the fuel rail.No need to actually try to start it just turn key on and off to activate the fuel pump. This is easiest with 2 people but you will be able to see if it is wet when you return to the engine compartment. Please just be sure you have no source of fuel ignition such as a hot shop light no smoking and things of the sort. If there is no fuel then your fuel pump is your problem. If there is fuel then look directly down at the crankshaft pulley and see if you see contact of the pulley to the plastic timing cover near the center of the cover if so and there are plastic shavings from the cover then you may have sheared a bolt and key way on the crankshaft causing the timing to be all off. This is a common problem on these trackers.

Old j reg mercedes 230te wont start

Check Injectors spraying Fuel when you start. Fuel pump prime because you hear the pump. IF pump is weak, then your Fuel distributor doesn't have correct pressure to spray fuel when injectors open. Do your sparks plug wet after trying several times. If they are dry then you don't have fuel. Replace injectors If they are wet then you don't have correct air:gas ratio of 14.6:1. Replace Fuel distributors
