ok i recently i got my fuel injectors cleaned and reinstalled. When i go to crank the car it turns over but won't start. The fan is working and i just installed new spark plugs. I'm goin to check if I'm actually getting spark tomorrow.
Anything else have any suggestions?
how can i check if the fuel injectors are working?

 

Pull the plugs and crank it over. You should get a bit of fuel out of trailing plugs.

 

I'm also getting this problem. Just got my 86' GXL about a week ago, but it has been sitting for 2 or 3 years. All plugs working and spraying starting fluid directly into the intake didnt do anything. The engine was working before the previous owner stored it.
