I'm working a crank-no start issue on a Hyster H60FT with serial P177V02769N with the Kubota V2403-CR-TI-EU3 type engine. I think it's a tier 4 engine from what I can gather online and it's throwing a code or multiple codes because the the engine fault code light is lit up on the instrument cluster. The problem is I can't read any codes on the instrument cluster screen as LCD screen is shot so I'm looking for another way to read the codes. I sat in the seat and connected the seatbelt in case it was a lockout issue but I doubt it because it cranks. I think Hyster uses a proprietary code reader that hooks to a 3-pin deutsch connector on the steering column so hopefully someone here has another solution for troubleshooting. Thoughts?
I'd check fuel rail pressure. These engines will crank all day but won't fire if rail pressure is low. Could be a lift pump issue. I'd also double check the FNR switch and parking brake interlock. Sometimes those act up even when it seems like it cranks fine.
Thanks, DustAndRay. As far the forward/reserve switch, the dash is saying it's in neutral with the green "N" lit up but it doesn't change when I go to F or R which is what I expect if it's not running. The parking brake icon goes on/off when I apply/disengage so I figured both the shift and parking brakes interlocks were working...let me know if that's not a good assumption. When I first started messing with it, I cracked an injection line but had zero fuel coming out during cranking so figured the problem was more upstream like a bad fuel cutoff solenoid. After digging into the only manual I have on this engine, I learned this engine doesn't have an actual cutoff solenoid like the older ones. Instead this one should have the suction control valve (SCR) that uses a pulsed signal to regulate fuel. I only had time to powerwash the engine before I had to leave but my next step is to verify fuel delivery is not an issue. I didn't see an external lift pump and I assume the 'fuel feed pump' is the only lift pump to the injection pump. I'll get back to the machine later this week.
