I was driving along, come to a stop and the ol' girl is just kind of sputtering like she's running on 2 cylinders. Shut down and didn't restart. will crank and hiccup a little. I disconnected the grid heaters and gave a little shot of ether and she ran on that. Cracked an injector and a trickle of fuel comes out. I'm hoping for a little advise. fuel to the filter & lift pump is running. Thanks

What codes is it throwing?

1693 with the key on/off. I don't have a code scanner. I'm gonna see if I can borrow one tomorrow.

HMX-1

1693 is a companion code, so you'll need to get a code reader to pull the other code(s) and find out what's going on.

P1688 is the code from scanner. Ouch!

Not sure if this will help, but according to the thread below, it sounds like you need a new injection pump.

Tell me about it! A buddy of mine lost his CP3 due to bad fuel, it also took out his injectors. Fortunately though, from what I found, your issue is due to the electronics.

From more research, some folks recommend replacing or upgrading the lift pump as well.
