Check for a bad engine control module or ECM fuse. If it is good, take out the ECM and take the cover off and look for a burned resistor. It is located behind the speaker on the drivers side lower dash.
Try checking fuel injector that is what the problem was with mine after checking everything else i replaced injector an fixes the problem
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
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
If the problem followed the fuel injector then it is a bad injector. If the problem stayed at the same hole with a different injector then it could be bad wiring.
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.
It can be either the IPR (Injector Pressure regulator) or STC Bracket.
If it is just one injector, it is a bad injector or a problem in the wiring harness or connector for that injector. If it is all of the injectors, it could be a fuse, the entire injector harness, a broken loose or unplugged connector on the injector harness, or the fuel pump or fuel pressure regulator.
Fuel injector
Running rich bad fuel injector?
Are you sure you are changing injector #7? Should be the injector closest to the firewall on the drivers side. If you are changing the correct injector, and the code remains, the problem is with the wiring from the injector to the pcm (computer) or the computer itself. You can check for correct battery voltage at the injector with a volt/ohm meter (how does the connector look at the injector?). This year of Durango/Dakota had trouble with computers too, although I have not heard of specific injector trouble being caused by the computer. Most likely a wiring problem. It may even be the TPS
No it is not a fuel pump problem. It either has a grounded are open circurt. Check wiring to injector. May just be a bad INJECTOR.
Typically that's when an injector "leaks" fuel after the engine is turned off, the fuel pools in the cylinder then the fuel slowly leaks past the pistons and builds up in the crankcase. It would be a good idea to find out which injector is causing the problem, or at the very least, run some injector cleaner through to see if you can stop the condition.
