Thank you for your reply, so great then I really screwed up then. So I'll have to remove the IP and have the CSS reinstalled and calibrated.
Calibration is only if you've messed with the stem of the CSD.

Yes there is fuel in the IP caseMaybe I don’t know what I am talking about - but I don’t see how cold start can cause no start.
Do you have fuel in the case of that IP?
Any pressure? Maybe overflow valve is stuck open. On those Isuzus they put them on the fuel filter return fittings sometimes.Yes there is fuel in the IP case
It wasn't the CSD. That was removed simply from a lack of knowledge.Maybe I don’t know what I am talking about - but I don’t see how cold start can cause no start.

Okay thank you for your help and the information. I will have to do some research on what shops close to me that knows anything about these pump.I'm not so sure the IP has to be removed. The tilt cab gives good access to any IP repair work needed, and I can't see where complete IP removal is needed. But you need to talk to an IP shop that deals with Zexel IP's and find out the exact process and cost required to re-install the CSD, and to retime the pump advance correctly.
Busby Truck Parts seems to be pretty knowledgable on the 4HE1 engine, they have YooToob videos showing the 4HE1 IP removal/replacement and timing the pump to the engine - but nothing as regards that CSS.
Can you send a photo or diagram of what cover needs to be removed? Is it towards the rear of the injection pump?Hello.. all ya gotta do is get access to the front cover.. remove it and put the solenoid back in..
It’s already set.. all ya gotta do is scoop the rack on top of the solenoid “leg”..
