Distributor cap and sparkplug wiring diagram - F-150 Ford Cars & Trucks

are plug wires--- disrt cap & rotor on correctly -fuel pump running ---jump timing -failing coil

There you go

Gasoline:1Common:Bad sparkplugs/sparkplugs wiring integrity/loose 2 Ignition platinum if apply.(ceck /under distributor cap/ also for dirt,humidity,rust,central carbon brush worn,loose,missplaced spring,eventually replace distributor cap ,if cracked,it looses spark power).3Too much gasoline.(ceck carburetor /tune) 4Very rare:ignition coil..Cheers

Had same problem with my 98 c2500 350cu in. Found distributor cap shorted. Take number three sparkplug wire off of sparkplug, let hang and try starting. Mine started, which let to bad cap discovery.

See diagram below.

Sparkplugs go down into the engine. You have as many as cylinders you have. Four cylinder, four plugs, six cylinder, six plugs. The plugs carry spark through the wires that hook to your distributor cap. Most caps are located on the right of the engine. That cap hooks to your distributor. So, if you have a four cylinder engine, you have four wires. You should see them crossing the engine block. The plugs are down in the engine block. The wires go into the engine block. Unless you have coils, which look like a small square, it has plugs.

Okay, lets start with the wires they are connected to the coilpack theres no distributor on the year ford, heres the sparkplug wire location, hope this helps, heres a diagram,

First you need to determin witch one is #1 on cap Witch usely is the one directly behind carb. or throutle body. than its perty strate forward from there rotor runs clockwise. Cap only goes on one way. Food for thought when you chg. cap or wires one at a time is the rule even for a seasoned mechanic.

follow sparkplug wires back to distributor cap. all wires will lead either to a distributor cap or a coil pack in the case of a coil pack its a closed system which is non servicable. hope this helps.

It should say on the intake if noti think the right side is 1 3 5 7 left is 2 4 6 8 if it back fires or dont start switch it around .
