93 geo tracker gets fuel, has spark, cranks but won't start
Put car back together after it sat for 3 years in a field.... gets spark, fuel in the carb, pressure a little low in #1 and 2 cylinders (70), distributor set at #1 straight on. Getting frustrated-no one can tell me what the problem might be. Have checked fuses; rewired O2 sensor...any suggestions?

does it crank at full speed. (called robust cranking)
headlamps work, full bright.
next is , is the dash cluster CEL lamp on key on? if not fuses are blown.
now crank, do you have spark to all cylinders?
no, fix spark.
yes, try test fuel?
Check all of the battery terminals and cables and check the wires on the starter/selonoid, start from the battery and follow the cable out and check all conections , clean and tighten them and if it still does it the starter/selonoid is bad and needs replacement...
Have you checked the fuel regulator and the pressure from the fuel pump to ensure it is not weak. In addition, you might want to check and see if fuel is going into the cyl. the catalytic converter may be plugged based on the year of the car. To check this you could pull the o2 sensor out of the exhaust and see if it keeps running, realize it won't run at 100%. If it is the back pressure will not allow fuel to come into the cyl.
I had this problem as well. The tracker had sat for 8 years and would only run off of starter fluid. I replaced the filter and fuel pump then I had no fire. Located under driver side dash in the fuse panel theres a fuse for coil. I don't remember which one, but, I am pretty sure it is a 10 amp fuse. Or just do like I did and replace any bad fuses. If that doesn't work it will be a relay located above that same fuse box.
You need to conduct tests to be sure where the trouble is.
1. Spark test: remove the number one spark-plug, and hold it to the engine block. then ask a friend to crank up the engine..
2. If the system is good, you should see steady blue sparks. If you don't, then you would have to work on your ignition system.
3. Fuel test: get a can of 'starting fluid' or the common 'choke and throttle-body cleaner'.
4. Unbolt the clamp holding the air-intake hose to the throttle-body. Pull back the hose to expose the inside of the throttle-body.
5. Spray a good quantity of the cleaner into the body.
6. Re-attach the air-intake hose, and try to crank up the engine again.
7. It will show some hesitation, but keep cranking until it fires up, and able to idle.
8. If the throttle-body and the manifold are dirty, the choke cleaner should help.
9. Please get back to me if necessary.
