no go
I have a 1990 E350 with a 7.3 over the past while it has been harder and harder to start (temp was minus 45 for a week or so) as long as I kept it plugged in it would eventualy start. I know the glow plugs are probbably bad and will check them. Now the new problem, last night I went and started the truck up and left it idling while I went in to get my coffee etc for work. It was smoking a little more than it usualy does on start (lots of grey-white smoke with diesel smell). However I came back out about 2 minutes after starting and the truck was no longer running. I went to restart it and it just turns over. The wts light does not come on nore does the relay click. Is there a fuse for this system, also does this system tie into the fuel injection system somehow. I removed the return line from the rear injector while turning it over and fuel comes out there, not squirting just running.
Any help would be apprciated as I need this for work.
Thanks.

On the front of your injector pump is the fuel shut off solenoid,there is a wire on it, remove the wire and install a wire from the pos of the batt and try to start.If it starts then you need to start chasing the power form ti sol back.Or if you have a meter you can unplug the sol and check the plug for 12v(with key on).This now could compound your problems(glo plug sys)BTW im sure there is a fuse for that,but

How cold was it when you started it that night?
If it was really cold you may have gelled fuel plugging the filter or lines.
The white smoke is because it was cold and if you have dead glow plugs the cylinders that have dead plugs are barely burning or not burning the fuel.
The glow plugs should have a fuseable link where they tie into the battery positive cable.
On the F series truck there is a connector with about 10 wires in it, close to the middle of the right valve cover that unplugs the engine electrical harness from the truck harness. The two big wires in that connector are the power to the glow plug relay. That connector is famous for melting and bad connections which will kill the glow plug circuit.
I was just looking at a van engine compartment a week or so ago. So I am gonna say up front, GOOD LUCK tracing those wires out. I only saw one battery, don't know where the other one is. Never saw where you put the oil in. I know there was an engine in there cause I heard it, never saw it, but I did hear it, it was a diesel cause I could smell the fuel.
