Other problem causing factors are a bit more complex but can be easily fixed or avoided. If the click is missing, the likely problem is the solenoid. Excess carbon around glow plugs or spark plugs.

Once you get it running everything is fine. It has an electric pump and that appears to be working as it runs fine after starting but it. The problem goes something like this (on a 1969 to 1985 diesel).

You should ensure you understand all of the causes, educate yourself on the symptoms, and take action before more damage develops. The ecu computer is the brain of the operation and it determines how much fuel the engine needs by receiving readings from various sensors like oxygen (o2), coolant. There are cases where this is related to the starter, the battery, or even certain parts of the engine.

Lots of vacum hoses replaced on. But after sitting overnight, you find you have to crank and crank until the engine fires. This is a warning sign that if these filters remain dirty or clogged, things will begin to get worse or break down.
