No Start Continuation

[Topless]

Failed fuel pumps are possible but relatively rare. Put 12VDC directly to the new pump to see if it runs. Now put 12VDC to the old pump and see if it runs. If they run, it's not a fuel pump problem and we are still missing something.

perhaps not getting fuel - something jamming up the pump? the fuel lines in the tank get brittle and break with age. perhaps you are drawing air? perhaps bits of plastic up into the pump?

The new pump has fresh lines to connect it to the fittings in the sending unit that connect to the lines to the engine. Also the strainer screen on the new pump was intact (incidentally, the pump is very similar to era Volkswagen pumps, just in a slightly different case).

Air is possible. Going to have it towed back to my dad's house again so he can work on it.

The old pump definitely failed the 12v test, repeatedly. When my car gets off to my dad's garage, we will test the new pump to see if it is still working. I would hope it didn't crap out already. Wonder if I should just go ahead and replace all of the relays for the DME/fuel system as a preventative.
