86 F350

460 CARB'D

Walk out in the morning to start it and it will start fine,

Run it for 10 minutes onward to 4 hours and shut it off and there is a 50/50 chance that it will start again.

Crank it over and when I let off the key, it will backfire/sound like it is trying to turn over, when the key gets to the nuetral position.

New Dist. cap, coil, plugs, and wires.

When the truck doesn't start I pull it with the tractor and it starts right away.

Any help?


Thanks

 

Woo Hoo, I bet you have a Holly 4180-C carburetor. Sounds like the electric choke or a fuel vapor problem.

Look online or have your dealer print these Technical Service Bulletins

871913 September 1987
861219 June 1986

 

I will try to find more info on those online but the is open when I try to start it, I will also close it and try to start it but the same thing happens. it is like it isn't getting spark or a sensor is out.

Thanks,


Anyone have an account?

 

Any chance it is an EEC III ignition. ( Large metal box module on the fender instead of the TFI module on the distributor) ?

 

I couldn't tell you right off hand, I will be going back to the farm this weekend and I will look.

Is their something I shoud look for?
