    No Power to Fuel Cutoff Solenoid

    So I lost power on the highway the other day. No warning, had been running great, just shut right off and wouldn't restart. On a whim, used a piece of speaker wire I found on the floor, and jumped the fuel cutoff solenoid to the battery, and it fired right up. Fiddled with the connector with no...

    No Windshield Washer Squirters

    Ever since I got my short bus (94 E350, N/A 7.3 IDI, E4OD), the windshield washer squirters haven't worked. Anyone have thoughts on where to start looking? I assume the pump is mounted in the washer fluid tank? Is it likely dead, or more likely just a wiring issue? I don't hear any pump trying...

    CTO wire

    Does anyone know if a 94 e350 will have a cto tach wire anywhere? Looks like newer trucks had one coming out of a harness by the break booster. I'm building a tach from a microcontroller, and this signal would be easier to process than the raw signal off the ip. It's an automatic, so the sensor...

    Axle gearing options

    I have a 94 short bus conversion (e350 based) with a 7.3 idi and e4OD trans. It feels like it is geared really low to me. No tach to really verify, I need to remidy that... It does 55-60 comfortably, but really struggles much over that, and the engine is screaming in 4th gear. With a diesel, I'm...

    No brake boost at idle

    Well pretty sure my vacuum pump is dying, just looking for some more sure diagnosis. Brake light has flickered since I got the truck, but brakes always felt great. Today, they started getting hard at idle. They are fine coming to a stop from speed, but if I then pump it a couple times, there's...

    Glow Plug relay clicks, but plugs don't cycle

    Just replaced all the glow plugs with Motorcrafts in my 94 7.3 non turbo. They have not been running. I replaced the glow plug relay a while back and I thought they were running for a while, but now, even with fresh plugs they are not. The relay clicks on, stays on for about a minute then clicks...

    Cruise Control?

    My 94 E350 short bus does not have cruise control. I plan on using it for long road trips, and it would certainly be a nice feature to have. Experience tells me driving a truck across Iowa without it blows. Is it possible to add?

    Electical Burning after hard start

    I've been chasing a suspected air intrusion. After sitting overnight, the engine will turn over, stall quickly and be very hard to restart. Runs rough while the air finishes purging, then idles out and drives great.. The other day while cranking too much and not letting it cool , it shot out...

    '94 7.3 tachometer

    Simple question: My Short bus E350 with a 7.3 IDI does not have a tach on the dash cluster. I really would like to have one. Does this engine have a tach sensor built in? I assume it must for the E4OD, right? How can I check, and what is the best method for adding a gauge? If it's got any kind...

    E4OD hard shift, trouble codes

    Finally got around to reading the codes off my '94 E350 Bus conversion. The transmission shifts rough and inconsistently through all gears (It will shift fine for a few shifts, then be real rough, not in any particular gear). The O/D light is flashing, though O/D does work. The button also seems...

    E4OD trouble codes

    1994 E350, trying to track down transmission issues. It is shifting really hard, and OD light is flashing steady constantly. OD still works, and button still turns it on/off. RABS light is also on. Trans shop told previous owner it was almost definitely the VSS, I replaced that, and it seems...

    First Diesel, looking for some advice

    Recently picked up a 19 passenger school bus I'm converting to an RV. I got it dumb cheap, but it definitely has some questionable history, so I'm looking to figure out what I should be doing to get it tuned up and prevent any further damage... It's a 1994 E-350 with the IDI 7.3 (non-turbo)...
