Won t start

My 1984 f250 diesel will not start. Just put in new glow plugs, checked fuses, power to selenoid, and it is pumping fuel to the filter. Do I need a new selenoid?

You may have power to the ignition solenoid, but you need to make sure you have power at the plugs. Take a wire off a plug, put a screw driver in the end of the wire touching the metal contact, and hold the screw driver close to a ground source (block, valve cover...). It should arc to the ground... What is the history of the truck? Did it ever run since youve had it? When did it die?

you can only do this on gas engines, diesels do not have spark plugs.

does the truck turn over or do nothing at all when you turn the key?

Yes it was running fine It started hard a few times but I thought it was the glow plugs Checked for fuel at the injectors and there was none. Then checked the pump and it was pumping fuel to the filter. I am thinking the fuel shutoff solenoid is bad

If you have the key in run, and pull the wire off the injector pump, you should hear it click.

Most failures like this are directly related to a recent change. Wrong parts used, not installed
properly, wires not connected properly, stuff like that. IOW chances are good that
something you just did is causing the problem.

You may have air in your injector pump. Open the line and keep cranking,
you will need good charged batteries, till you see some diesel come out.
Put the injector line back and crank again.

You can take a little risk, shoot "a LITTLE" starter fluid in at the air intake (filter removed) when the crank go up to speed, as soon as the engine start
pump the gas paddle.
