Flatbed24v

It was driving just fine, parked it, two hours later went to go home and won't start. The tank is full, but it just cranks with no fire. I do get a 1693 but haven't found the other code yet. It has 198,000 miles and that's on the original factory vp as well. I know the vp has gotten weak but never acted up like this but I guess it's time for one. After I cleared the code with key I would try starting it and one cylinder would fire then nothing with the check engine light coming back on. Is there any other problems that could cause this besides a vp problem? I will try to get the codes to confirm but I am hoping there is an other (cheaper) problem. Any help or advice will help, thanks

Good lift pump fuel pressure?

When my VP let go, it didn't show any codes and wouldn't start without a shot of ether.

Scan it. If no codes search on CKP. You really need more info before throwing a VP.
