Hi, I have a 87 ford 350 with carb mini cab over camper. Went out to move it yesterday to get ready for next weekend campout and it would not start. It turned over fine but would not start. I suspected it was not getting fuel so I removed the air filter cover and could not see any gas squirting into the carb. I sprayed a little starting fluid in the carb and it cranked ,then went dead. I suspect either a cloged filter or bad fuel pump. I need some help on how to find the problem. It has a screw on fuel filter back along the frame and I think one at the carb. Does the 12v power that runs the pump go through the fuse panel, anyway any help will be appreciated. worse case I guess would be bad pump in fuel tank. Is this something a shade tree mech like myself could replace. Don't want to spend a lot on a 87 model. Just recently had a exzause manifold replaced and air conditioner work done. Thanks John in hot Mississippi

Start with the basics. If it is carborated then it is fairly easy to check for fuel. IF it is fuel injected, then it is harder. Next check for spark. I suspect no spark, but again back to the basics.

Since it fired on the starting fluid your spark is ok.

Disconnect the fuel line at the carb and run it to a safe area and have someone crank the engine over a few times. Depending on how the fuel pump is connected you might have fuel as soon as the key is on so be very very careful.

Before doing this I just remembered. On some models there is an emergency fuel shut off device to protect you in case of a collision. This could be mounted behind the right passenger side kick panel. These things sometimes trip for no apparent reason. If you have an owners manual check that out.

I would also check for any fuses associated with a fuel pump.

I would just add that if you don't have the manual. I believe it is a reset button that you push...


But that's just with an electric fuel pump right? A carbureted engine would have a mechanical fuel pump...wouldn't it?

My old motorhome was an 87 with a Ford 460 and a carburetor. It had an external electric fuel pump mounted on the frame behind the left rear dual. I replaced it with a new Holley pump. That motor also had an oil pressure sending unit which would shut off the fuel pump if oil pressure was lost.The switch can be jumpered to check if it is at fault. I permanently bypassed my pressure switch because it caused the engine to crank a long time before starting.

Just for fun, check the fuel filter.
