Fuel flow question Universal diesel
I got my 1981 Tartan 33 a few months ago, just motored (a little sailing) 110 miles down the ICW with no issues. After sitting for a month (has sat for a month at a time before, no problem) and adding about 10 gals of highway diesel to the tanks, the engine now won't run.
It initially started and ran for a few seconds, then won't run. Here are a few things that make me think it's fuel flow:
- If I pump/prime with the throttle several times (10-15), the engine will run for a few seconds, then stall out.
- Typically when starting my engine, I have the throttle just slightly up and it starts. Now, it doesn't get close to sounding like starting, but with throttle on max, it sounds closer to getting up to starting speed.
- Doesn't seem like it would be a glow plug issue since it will start and run for a bit.
So, I have replaced the fuel filter. Let me say again, diesel engines are new to me (or I'm new to them). I'm guessing either fuel pump, or perhaps a short in the wiring that powers the pump?
- are there any other tests I can perform to isolate the problem?
- priming? I called a diesel marine shop and they said it may just need primed after sitting (I should add that temps here in NC have been in the 90's with higher humidity, whereas when I've let it set before, much cooler and less humid - don't know how that would influence the system). But, if I can get it to run briefly, doesn't seem to me like it would be a priming issue, more of a flow issue.
- Is there a pump/lift inside the fuel tank, or just on the outside? (attached pic)
- Are there any other factors I should be considering?
If you've made it through, thanks for your time! And, thanks in advance for your expertise.
