sounds like a computer issue on the burb, but i would check the IAC(idle air control) valve and the TPS(throttle position sensor) first.
I would start with the IAC on the 93'.

change fuel pump if you can I have same exact problem solved after changing fuel pump

The Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type.

honesty no idea without a good look please ask a local mechanic to have a look

Does this vehicle have 4 wheel antilock brakes?

Your ecu is most likely the problem if it is bad it wont send power to the fuel pump. You can check it by turning on the ignition then listen for noise coming from fuel tank. You should be able to hear the fuel pump come on.

A mechanic would check for power at the motor and at the resistor.Also check the motor ground circuit for a loose connection.You can look the resistor up at the online auto parts stores to see what it looks like.

It sounds like its related the the wheel it could be a brake caliper thats sticking sometimes Iwould pull the tire off and check to see what kind of shape the rotor and pads are in look for one of the pads to be likely the inside one to be much thinner then the outter one the ware limit is around 80-100-ths of an inch

If you have no reverse, it has to come out & come apart again
