Expert's Assistant chatimg
Customer: Shogun starts first thing. Runs for a minute or so and shudders to a stop. starts again, same issue. Third time starts and is fine for the rest of the day. Valve fitted to fuel line to prevent fuel running back. Is this the beginning of the end of my fuel pump??
JA: When did you last fill the tank? And do you smell gasoline around the engine?
Customer: Yesterday, full of proper diesel and addative and no smell. All fuel lines around pump are bone dry
JA: What is the model/year of your Mitsubishi?
Customer: Shogun V46W 2800 Turbo diesel
JA: What year is your Mitsubishi?
Customer: 91?
JA: Are you fixing your vehicle yourself? What have you tried so far?
Customer: no. Just the valve to see if fuel was running back to the tank
JA: Anything else you want the Mechanic to know before I connect you?
Customer: all filters brand new and originals fitted last month

Hello, my name is***** have been with Just Answer since 2009 and have been working on vehicles since 1992. I will be happy to assist with all of your questions. I am usually online until late evening each day, if we happen to miss each other, I will follow up as quickly as I can, in some cases this may be first thing in the morning depending on the time you respond.

You may see a prompt to receive a call, you can agree or decline. If at some point you feel you need to speak on the phone feel free to request the call on your end.

Have you had the fuel pressure monitored or inspected when this issue occurs to see if your losing fuel pressure or losing fuel volume at all?

Let me know so we can continue.

Thanks, Pete

not had fuel pressure checked but not losing fuel

Thank you for your reply and that information as this does help.

I recommend having the fuel pressure tested to see if your losing fuel pressure with this issue. A loss of fuel pressure will cause the problem that you have described here and this loss of pressure is usually due to a weak, failing fuel pump needing to be replaced.

If you need to continue or if there is anything else I can assist with at all, let me know here and I will be happy to assist further.

Thanks, Pete
