Sudden no start

Yes, air can cause that.

Now that you can start, make sure engine is running.
Open the t-valve and see if you can keep it running.

You can test the PMD somewhat with the info in this thread. After the above I would replace both the OPS and relay for the lift pump. Both mechanical and both have limited life.

T-valve? Is that the air bleed valve screwed into the top of the filter housing?

Thanks for the link. I'll go through that this weekend and see what it turns up.


BTW, I think I'll replace the fuel filters and the O-ring on the shaft of the air bleed valve - along with the OPS and relay - just for good measure.

The new fuel filter will come with a new valve and o-ring. The top of the housing you see is actually part of the filter replacement. Make sure like said you use a A/C delco OPS replacement.

The t valve is the brass one near the oil filler cap.

Valve on top of the filter is the air bleed. The brass t-valve by the thermostat is the water drain.
