Engine will not start, could use advice quickly

[Ron Hill]

PK : The solenoid is for the glow plugs and has nothing to do with the fuel pump. 
The fuel pump will come ON when the glow plugs are activated in the spring position of the key switch, but when the key switch goes back from the spring position the fuel pump will only stay ON if the engine has oil pressure!

A thought

I asked PK what his resolution was on his blog:

In retrospect the solenoid was probably going bad or was spotty at best and the failure of the oil pressure switch brought it to light. We ultimately replaced the oil pressure switch, the glow plug solenoid and the breaker on the solenoid (I don't think the breaker was bad) Now the engine turns over better and quicker then ever before. Thanks again.
