1994 F150 Turns over won't fire, intermittent problem. First thing that happened was coil pack condenser sparked blew 25 amp fuse, replaced both, ran great couple days then started this cranks won't fire thing that is intermittent. Garage replaced relay, ignition replaced, plugs and wires replaced. HELP left me stranded(Miles away from home) after 4 days in the garage where these thing were done. The fuel pump comes on and pressurizes but it will not fire. Tried jumping the fuse still won't start. I need HELP!
