it cranks over and everything. its just wont start no fire at all. just turns over. i am replacing the alternator right now. and what do you mean that the ignition has a pulse? i do not have any spark at all. yes my headlights are working. and i rebuilt the injectors and that whole set up about 5 months ago. i have not installed an ignition box. can that be the problem why it doesnt want to start. i have also looked at the fsm and that doesnt seem to help at all. any suggestions on stuff i can just replace to get spark. i know that is the problem. i get fuel and everything i have sprayed starting fluid in the carb and i can also smell gas. i just have no spark. i have replaced the plugs, wires, cap and rotor, pick up coil and now the alternator. i know the alternator probably has nothing to do with it but it need one anyways.
