I have decided to take out my 90RR after letting it sit in the garage for two years.
I hooked up a new battery, it would crank, but would not start. I realized that I did not add any fuel stabilizer before storing the vehicle. If the old fuel did turn to varnish and clogged up the injectors, can these be resurrected, or is it necessary to replace them?

I don't know where to start to get my vehicle running. I would appreciate any advice. Thanks, guys!!

You could start off with a quick shot of starting fluid into the breather hose (before cranking). You should reconnect the hose before trying to start it since the breather has a flame arrestor (just in case...) If it starts briefly, the problem is likely the fuel pump or filter. Possibly the fuel pump mounting plate has deteriorated and the electrical connections are shot. I bought a '92 that sat for three years and the plate and connections were corroded beyond salvage. A new pump got it running great.

 

I agree, use some carb spray into the t/body then try to start it, don't pump the gas pedal. Try this a couple of times using a good squirt of spray each time, it should start up.
Let us know.
