Check any wire running near your transmission. Especially running behind or within the lever, on the transmission that shifts to drive. It's a long shot but something is shorting out somewhere to do with your shifting movement. Good Luck Darrell S

That means that there is a short to ground that occurrs when you put in gear. Check dipstick tube, wiring to TCM and wiring from TCM to transmission shift solenoid.

Problems of this kind may be difficult to spot.
The repairer must patiently work with tester on connectors and wiring harness to spot the problem.

When the problem is a short, like in your case, reading Ohms between two points with engine off may reveal a short to ground more easily than reading volts with ignition on.

The fuel pump fuse keeps blowing in my 92 grand am

So it is the injector fuse, not the pump fuse? The injector circuit must have a short in it, or an injector may have a short and be bad. Have your injectors tested with a "resistance test"-they do not have to be removed for this.If injectors test out good, you need to inspect the injector harness for bad wiring. Maybe you missed some of the melted wires?

Auto shut off relay keeps blowing

I would suggest after what you have replaced yourself, so far, that you
seek professional help.
At least ,you would need wiring diagrams & some experience testing
those type of possible electrical issues

When i try to reverse in 4wd, my fuel injector fuse blows, but i can reverse in 2wd just fine

After looking over a few dozen schematics, it looks like fuse 26 is a 15 amp fuse that goes to the PCM among other things. One of the things in the drivetrain that might be powered by that fuse is the transfer case position sensor. The sensor is not shown having its own fuse but gets power from the PCM.
If that is the same fuse you are talking about, you might try unplugging that sensor and see if the fuse still blows.
Otherwise you may have to buy or download a service manual with the wiring diagrams and search them for what is powered by that fuse.

Fuel injector fuse is blown, keeps blowing. Engine turns but won't catch and start.

if the injector fuse is blown then the car won`t start as its not getting fuel into the motor to fire.if the fuse keeps blowing then you could have an injector/s that is drawing too much or the injector driver in the ecm may not be any good and needs replacing or a used could be a short some where in the wiring for the injector system that is going to ground.

The fuel injector fuses keeps blowing as soon as i open the ignition switch, it dosent even give me time to turn on the car before it blows again. the car has a new fuel pump installed by jiffy lube about...

There is a short circuit to ground on one of the circuits that the fuse protects. I need more information about your car and exactly which fuse is blowing. (Year, Make, Model, Engine size) All of the circuits powered by that fuse must be traced to find exactly what is causing it to blow. Most of the components can be eliminated as the cause by unplugging them one at a time and checking the fuse connector with a test light. (Otherwise, you could go through a lot of fuses trying to figure it out.)

EEC fuse: 1992 ford explorer

sounds like you have a bad relay that is shorted out or you might have a bad fuel injector shorting out fossible fuel pump wireing short do some probing aroun with the multi meter try to find direct short , use the process of elimination .
now let me see does your truck start up and run then fuse blows? is the fuse the correct amperage check your owners manual to see how long does it run before blowing fuse ? when its running is it running smooth while is running?

EFI fuse blows

You have a short in one of your fuel injector wires. Check the wires from your fuel injectors for burns or cuts, look for bare wires grounding out on medal
