check the plugs, wires, and distributor. if those are good, clean the injectors.

i used to do a lot diagnosing and theory for a shop i worked, and had a couple fox bodys and some sn95s in with no firing problem. what i found was that the ijectors in deed werent firing, but the problem wasnt the injectors it was pcm (computers) were bad. my first one was a fox body, and i replaced the injectors (likr a $600 bill for the customer) that wasnt the problem, needless to say the customer wasnt happy, so i spent 8 more hrs. chasing wires the i found it, the computer had failed. so not to scare you but you check the wire connectors on the injector for solid ground on eiather of the wires its the pcm
