I've been having problems starting my car after it has been parked for the winter. I've narrowed the it down to the main injectors not firing.

I'm looking at an engine wiring diagram for my car, It shows:

ECM IGN FUSE 10A
INJ 1 FUSE 5A
INJ2 FUSE 5A

Where are these 3 fuses located on the car?

It's the 5 amp fuses. One is for the 2,4,6 bank and the other is for the 1,3,5 bank.

There are in the fuse block under the dash

Phil, Under the drivers side dash with the rest of the fuses??

Here are some threads of interest:

And something I posted in a thread not too long ago:

The injector circuit supplies power straight to the injectors via the INJ fuses, and the circuit is closed and the injectors activated by the ECM providing ground. Check for power on both sides of the injector fuses with a voltmeter and the key in RUN. If no power, then the fusible link back at the terminal block by the battery and C500 connector may be bad. If power there, unplug the injector harness over by the thermostat and check for power there. If no power, then there's a problem with the wiring. If power is ok, then the ECM is either not providing a ground path or the wiring to the ECM is bad. Also, have you checked for actual fuel pressure? You can rent a fuel pressure guage to check that.

Oh well HELL I thought he at least knew where the fuses were. Sorry I misunderstood the question.

This brings nack a memory of I beleive my first post of PFF back in 99. After my Fiero rebuild, the first time I tried to start it it only ran on the far bank. I checked and checked the injectors and circuitry but finally found a blew fuse under the dash. I replaced ALL the fuses since the car was sitting up for awhile, and then it ran and drove fine. I still to this day, however do not know where the blue dingy thingy plugs in. When I got the car it was on the floorboard and I never found out where to plug it in at. I always thought it would be cute to wire it in as a reverse backup dingy in my V8. Just imagine the rumble of the V8 bumping in gear to back out of the drive in and to hear that elf banging on the xylophone LOL........

The blue ding thingy plugs into the "convenience center" - it's under the dash on the far passenger side, bolted to the heater housing. Your horn relay and the emergency flasher also live there...

HA !! Wish I'd seen that 2 years ago. LOL..................
