1992 Geo Tracker wont start,no fire or fuel

Rotation is different between 8 and 16 valve engines. See picture.

old post, this car is not 1991 and newer that do have a FI fuse.
this generation 1.
it uses 1 fuse for ECU , spark and pump.
called IG-COIL
as seen here
for others, with this car the below is key to whats there. EFI wise.

fuel to the tbi, but no power to the injector means the wiring or the computer is bad and won't fire the injectors.

STRAIGHT WIRE FROM COIL TO INJECTOR
COMPUTER GOING BAD

CHECK FUEL PUMP FUSE.AND CHECK IGNITION TIMING ALSO SCAN IT TO MAKE PCM IS GOOD.FUEL PUMP WONT TURN ON IF PCM OR ECM FAULTY.

Sounds like a bad ECU module it controls fuel injection and spark.

The ECM has a blown capacitor inside it for opening the injector you will most likly need to get it rebuilt, buy a new ,or used ECM had the same problem with my sidekick.

15 amp fuse in fuse box under the dash...by the drivers left leg.

You may have an issue with the fuel pump crank circuit, check the ignition switch, I think that may be the problem

The fuel pump has 2 sources of power, when you crank the engine power to the pump is supplied through the cranking circuit of the ignition switch, after it starts the power comes from the run circuit, you most likely have an issue with the ignition switch.
