6BT – abrupt stop; cranks but no start

[DeWayne Enyeart]

While trolling at idle for salmon 5 days ago, the engine abruptly stopped. The engine cranks but no start. Trouble shooting thus far:
1. Both fuel tanks nearly full
2. No water in the Racor bowls
3. Battery voltage before start attempt: 13.2
4. Voltage at the fuel shutoff solenoid: 10.6
5. Removed & inspected the fuel shutoff solenoid: no obvious damage
6. Bench tested fuel shutoff solenoid with a new 9 volt battery: the plunger retracted promptly
Next step suggestions would be appreciated.
Thanks

DeWayne, Thanks for the excellent photos that you included with your posts.

Squeeze Bulb Fuel System Priming

Glad you got it..The CAV/Delphi fuel system is very hard to prime following typical guidelines.. Set up right, a common squeeze bulb is an amazing but simple tool to get up & running if you’ve run out of fuel.

So, you pulled the solenoid and removed the spring & plunger and re-installed.. GOOD..

As to re-priming, this pump can be a challenge without a priming bulb and/or an electric pump..

The fuel flow is so low, just install a high quality 3/8″ squeeze bulb in a convenient spot in-line with no bypass, and prime away .. If you had a clear return line, you should “see” fuel coming out of it..

100% Throttle –You may have to crack 2 easy to get to injection lines to prime and initially start on 2-cylinders–It will clear, eventually .. Not like a Bosch 6BTA system.

If it does not pump fuel to the injectors, the shaft broke (or ??) inside the pump–I have see it..

I installed a squeeze bulb in the fuel line and pumped it until hard. With the throttle at WOT and 2 of the injection line nuts cracked open, the engine started.
Photos of the squeeze bulb installation are attached to this post.
Thanks Tony for your suggestions.

Tony:
Yes; my injection pump fuel solenoid looks like your picture. The fuel injection pump face plate contains the following info:
Brand: Lucas
Type: 1330
Part #: 3369F330X
I removed the piston/spring from the fuel solenoid and replaced the empty solenoid. The engine cranks but does not start after 3 tries with WOT.
My next step is to install a squeeze bulb fuel line primer the “Seaboard Way” and attempt to start the engine again. Pictures are attached.
If my next step is unsuccessful, what should I try next?
Thanks

Does you injection pump fuel solenoid look like this?

Just to make sure….tie – wrap the fuel solenoid in the activated/pull-in position and try cranking.
