ello everyone! After a long time of looking I finally bought a 94 f350 dually powerstroke and I couldn't be more excited. The big catch is that it has been sitting for 2.5 years and is not running. I've taken on quote a few projects before but this is my first diesel. So far ive:
-Replaced fuel pump along with all the hoses
-Changed fuel filter
-Drained the tanks and refilled with some seafoam added
-Checked hpop reservoir
-Changed oil of course
So the tach bounces around 100 when trying to start but doesn't move past that(is that too low for this?) It looks to have blow by when trying to start
The fuel bowl is getting filling/refilling
I tried unplugging the ICP sensor and that's where I'm at now, running out of ideas. Oh and the number 22 fuse is not blown even replaced it to be safe. The wait to start light comes on and goes off, I'm not sure if this matters but it doesn't have a clutch slave cylinder or master cylinder installed at the moment so I've been jumping it from the starter relay to attempt to start. It can crank all day but doesn't turn over at all.
The clutch switch goes on the pushrod for the master cylinder. Not sure what's so odd about that.
Re the RPMs, it depends on whether it's _really_ going that slow or not. You should kinda be able to tell that by ear. IOW, if by ear it seems to be cranking "normal" cranking speed, but the RPMs are showing low, then yes, the CPS is suspect (is it Ford/Motorcraft or IH, BTW?). If it's actually sounding like it's only going 100 RPM, then it's starter, battery, main starter wiring, etc.
