I have recently replaced the fuel pump and the vehicle was running fine and then the cpi went bad and so I replaced it as well and put new plugs in and went to start the jimmy and it wouldn't start, there is no spark from the ignition coil, I know I need to check the coil, but I was cleaning the intake with spray intake cleaner while it was apart and some spattered on the distributor and I wonder if that would cause it, even though its a closed component, any ideas, it sat for 2 months with out running and had spark when parked, so something went wrong while it was just sitting there.

No spark at the coil indicates a bad ignition module. You probably sprayed cleaner on the module without knowing it. The module has white heat dissapating grease on it which helps keep it from frying up. You probably cleaned all of the grease off. Have the ignition module tested (as these are a little pricey). Autozone or a place like that can do this for free -- on or off the Jimmy.
