Hi. Thanks for using JA. I will try and help you out.


Does the engie smoke when you are trying to start it?





Also, when you say it is getting fuel, how can you tell? Does the engine have a hand primer pump?

no smoke, no primer pump

 

it is getting fuel from the main filter, and it has fuel coming from the return line going back to the tank ..pulled lines loose to see this

Technician: Cat Man, Caterpillar Engine Expert replied 7 years ago
Thanks for the information.


The reason I asked about the hand primer pump is because it takes at least 35 psi to make the engine run. If you had a hand primer pump, you may be able to operate it and the engine may crank. But since you do not have a hand primer, the only way to verify this is to install a psi gauge in the fuel filter manifold and measure the pressure. If it is low, you either have a failed fuel pressure regulator or transfer pump. Since you seen fuel returning, I would lean more towards the regulator.

where is the fuel pressure regulator located? I have a "pick up" fuel pump that is gear driven, bolted to the front of the engine.
Technician: Cat Man, Caterpillar Engine Expert replied 7 years ago
The regulator is located in the secondary fuel filter housing. It underneath the bottom beside the filter. It looks like a 1 inch plug.

Is there a way to check the regulator, without replacing it?

 

 

Technician: Cat Man, Caterpillar Engine Expert replied 7 years ago
The only way would be to cap off or restrict the return line. If the engine starts. You'll know the regulator is bad.
