I can not get my Bobcat 873 to start. Fuel flow is good.

Customer Question

Hi. I can not get my Bobcat 873 to start. Fuel flow is good. Glow plugs are good. It will turn over and even fire up with diesel safe starting fluid, but will not run.

Hi my name is***** will be glad to help. Do you have any BICS controller codes? What is your serial number?
Customer: replied 7 months ago.
Hi Dan. The only code is ES-6. Serial ####-##-####Model 873

Check for power at your fuel shutoff solenoid with the key on and cranking. If there is no power there. Click on this link for the shop manual in PDF.Manual

That means no sensor signal. Click below

Yes I read the ES-6 code, but that has occurred before and doesnt keep it from running. Fuel flow is good to all cylinders/injectors. I cannot find the fuel shutoff solenoid, but even if I could, it already seems to have good fuel.

Can you offer any other advice please?

Hello again Dan, the answers you provided did not solve the problem. Can you offer any more advise, please? Again, good fuel flow all the way to injectors, good glow plugs, will start with starting fluid, but will not run.
Expert:  Dan replied 7 months ago.
Are you getting any signs of smoke from the exhaust while cranking over? Please give me the complete engine make/model number from the ID tag so I can be sure to give you the correct information for your fuel system. For starters check for leaks sucking in air and restrictions between the tank and pump. Install a clear hose inline to watch for bubbles present. Also try to run a hose from a separate container and bleed the fuel system to see if it will start. The shutoff solenoid will be mounted to/connected to the injection pump. Let me know
