the car was parked after i got another one. it ran fine when parked. it's been started since but the last several times it will no longer start. tried starter fluid. some tell me it could be the module. it's getting gas. where would one begin to look for the problem? where can i find what causes spark to what in what order.(exp) ignition to plugs to battery to whatever. it has a very strong crank. it has sat for awhile now. none of the wires look corrordide. any suggestions?
