Firstly do not hot wire the injector it will either fry it or the injector circuits in the ECU.
There are two transistors that control the injector circuits on the board.
But the most common fail are the 3 can shaped capacitors
Check out www.suzukiforums.com or better yet http://www.kick-fix.com/index.html for full detail on how to repair the ECU.
I have recently completed this repair and it worked like a charm.

possible problems are: The fuse is blown, or the injector is bad, or the wiring to the injector is bad, or the computer is bad
I had to replace the injector itself the other day as it was not allowing the fuel to go into the TBI unit. I used the injector test light on the harness and it show the computer as being good.
The most common problem, when a 1990 Geo tracker floods out with gas, is a bad fuel injector. The injector might be leaking or injecting a steady stream of fuel
No !

Usually the problem with this computer is that the capacitors leak inside the computer causing the traces around them to erode causing no signal to the fuel injector. To test, dump a small amount of fuel down the carburetor. If it fires, then you will need a new computer or you can have it repaired.
Probably a sticking injector. If it's throttle body injected, that might just be the lowest port in the intake manifold, and the fuel runs into #2. If it's port injected and there is an injector for each port, check the #2 injector. It's probably sticking open.
Try checking fuel injector that is what the problem was with mine after checking everything else i replaced injector an fixes the problem
you replace it
Under the dash left of steering column. If you take out the left speaker by the door you will find the bolts to remove the bracket. The capacitors in the 1990-1995 are junk but easy to repair. Never try to hot-wire the throttle-body injector to get it running as this will blow out the two transistors in the injector circuit as well or the injector. I have an easy inexpensive fix for no start no fuel problem with these. On_mitch Hi, I'm interested in the "fix" 1badbaby
the plugs are going through the rocker cover under the fuel injector
AnswerComputer controlled and not adjustablethere is a way by tightening throttle cable or screw by throttle body ( but i would check o2 sensors first)
