No glow plug ready indicator, no start

[orbyone]

Hi, I'm in a bit of a jam. I'm getting my 95 7.3L powered RV ready to go to the lake and all the sudden I don't have the usual indicator on the dash telling me the glow plugs are being energized, and it won't start.

Prior to that I checked all the fuses in the box where the 50 and 60 amp fuses are at trying to find why my A/C blower in the dash won't work. I also checked all the fuses in the smaller fuse box under the dash. I just checked them all again, nothing blown, no blank spots.

The only thing I can find in the Chilton manual is how to change the glow plugs and test the relay. I doubt it's the relay, I was no where near it.

Anyone have any ideas? I've got 10 grand kids salivating at the thought of going to the lake to learn how to water ski and go fishing so I gotta fix this.

Thanks. : )

See if you can find the fuse for the fuel heater in the underhood box (30A). Check it with a meter and not by eyeball. If it is blown, disconnect the fuel heater (drivers side of the fuel bowl about halfway down the side with a funky-looking spade connector) replace the fuse and try again. Cheers!

Thanks Patrick, I'll try that. My Chilton manual doesn't say which fuse is for the fuel heater so I'm going to pull the driver's side battery so I can get to all the fuses in that lower box and ohms test them all.

On the trucks it is fuse #22 (30A Maxi). Cheers!

if the fuse is blown, chances are the fuel bowl heater element has shorted out. if thats the case you can just drain the fuel bowl and remove it completely. mine has been out for 2 years now and ive never had a problem - even in winter.
