When it cranks does it sound like its hesitating or off time or does it sound like it usually would when you go to turn it on? If it hesitates or sounds like it misfires or misses try looking if your spark plugs are good! If they are then the next step would be make sure your getting spark from the distributor! If your distributor is fine and it still sounds like hesitation then perhaps you have a fuel problem..what you want to do is unplug the connectors connecting tobyour fuel pump take off intake so all you see is the throttle body! Open that up and spray some starting fluid into the intake manifold (its in a can) this will check if you have a fuel problem! If it busts off with the starting fluid being sprayed into the intake then your problem is either fuel pump or bad/dirty injectors but before you do anything check to make sure the battery has enough charge to start the car!!!
