Ford E450 6.0 Powerstroke - No Crank, No Start
Hi all,
I'm having a bit of an issue with my rig regarding starting. Here's what happened that I know of:
Over the summer I drove to PEI from my hometown (about 350 km) as the first medium distance test trip for my conversion. Right before I got there I experienced some weirdness with the transmission and the speedometer acting wonky. The ABS light had been on before this trip but I attributed it to something minor initially so I didn't bother troubleshooting
The bus has started, ran, and drove plenty of times in between then and now but yesterday I drove it and the speed sensor (which I figured was already semi-faulty) must have finally failed as the speedometer dropped to 0 and the transmission remained in first gear. This problem was confirmed by a code reader.
When I returned home, I parked the bus and thought nothing of it besides the fact that I'd have to replace the sensor and that would be the end of it. Now when I go to start it, all I hear is a "click" (normal sound). The engine does NOT turn over at all.
My dad hooked up some device I'm not familiar to the starter underneath which acts as a ignition and bypasses the starter relay. Using this method starts the engine successfully so the starter is fine as far as we know.
Does anyone know why this might be happening? Is it possible that the ABS light / speed sensor failure would cause the starter "circuit" to be interrupted?
Thank you in advance.

The bus not cranking over is a different issue not related to your initial problem. Start with the basics like batteries, battery connections, starter connections, etc

Yeah, well it technically starts when you bypass the starter relay which is obviously a huge hack. To me this means the batteries are not an issue and the starter is not an issue (as far as I'm aware). I'm just wondering if anyone has experience with this particular situation regarding the no crank.
I also just checked the starter connection and it's fine as well (I bypassed the yellow-blue stripe wire that feeds into the starter relay straight to the positive terminal on the battery).

Yo can put a meter on the solenoid's trigger side and see if its being energized, that would tell you if the solenoid is the cause of the issue or just a symptom. If it's not the solenoid, it'll surely be one of the safety lockouts, ie the sensors on windows, doors, and the neutral/park sensor on the transmission.

If you can jump the solenoid and start it. Something is wrong with the control side of the starter circuit. Check any safety interlocks to make sure that none of them are open or faulty. Make sure it's in park, and if it is, try shifting it to neutral and see if it will start. If it still doesn't start, you'll then need to pull up some wiring diagrams and see where you lose power at be it the switch, relay, etc.

I’m having the same issues
Hello Jessi,
Did you guys ever figure out what was happening with your rig? I’m having the exact issues you were having when you wrote this post.
My batteries are good and charged, I have a brand new starter as well. I’ve double and triple checked that all my wires are connected/ no copper is exposed, but still can’t get the rig to turn over.
I also noticed that the last time I drove it, my speedometer didn’t work. I bought it from the Sonoma County school district and know it to be in really good shape. Why can’t I get this thing started?
Please help.!!!!!

Hey, yeah it turns out the wiring to the fan clutch got chewed out by the fan at some point. Once this happens the computer will prevent the vehicle from turning on since the fan won't be able to cool down the engine/radiator. Once I replaced the fan clutch it worked again.
