To anyone out there, can you please help me. I have 1986 Ford F150 and the left side is not firing. (The passenger side of the motor.) Can someone please help me in troubleshooting this problem. Also please e-mail me at this address: cajun_rue@yahoo.com




Thanks

Need more info.
Is it fuel injected?
How do you know it's not firing?

 

I saw something similar to this a LONG time ago. I don't remember all the details but it was on an injected 302. I believe that the right and left banks had seperate grounds for the injectors and the ground on one side was bad. I might be leading you down the wrong road this was quite a while ago.

 

It's fuel injected and we tested it by taken the spark-plug wires off one by one and touched it to the dis. cap. The right is firing just fine. But when you check plugs 1-4 it's not firing like the right side.

Thanks for the info so Far!!!!

 

I have limited knowledge of this engine but i believe it would be throttle body injection? Does it have a coil for each bank or one runs all? If it has one for each bank then i would suspect the coil for that bank.
Also not being rude but for future referance the passenger side is normally refered to as the right side.
