If your truck is the 300 check the ignition control module. That went out on me and my truck wouldnt fire up. If it is that when you turn the key the fuel pump should turn on. If you cant hear the fuel pump check it. If thats all good check your distributor cap and your spark plugs. Hope this helped
Spark plugs are new an disturber is new what else can be wrong
I'm having the same issues with my 91' F-150 !!! Replaced everything that has to do with the fuel line... Even replaced the computer!! Will run every time when I spray gas into the throttle body.... But, won't run on its own....
1989 F150 i6 4x4 5 speed. Fuel Tank Full. Spark checks out. Prime pump pressure checks out. Starts on brake cleaner. No codes or system ok. Havent replaced the ECM yet. Shut off while doing 65 on highway after running for a few hours.
Having same problem with my truck but when I put a score drive to the ignition coil it dosnt spark to the screw drive it sparks down towards the coil could that be the problem
