Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 M3W fuel pump issue?

Hi All,

My M3W engine died while idling in the drive. Several attempts to start yielded nothing. Checked for spark and it was there. A bit of starting fluid in the intake and it kicked over but would not continue. Checked the Schrader on the fuel rail and had no residual pressure.

Let it set overnight. Turned key and finally heard fuel pump spin up. It started, but only once. No more fuel pump sound.

Seems like a fuel pump or relay (if there is a fuel relay). Is there a diagram or schematic available that could show me how the fuel pump is wired and what each relay is for?

I'd love to take her our for a casual Sunday spin.

The fuel pumps have been known to go bad. I'm on my 2nd one.

This helped, thank you!

I isolated it to the actual pump. Pulled pump assy from tank (took me a bit of time to figure out how to detach fuel lines. Easy but not obvious).

I removed tested the pump assembly with a 13V power supply. Nothing. I pulled the pump motor and gave it 15vdc direct to the leads and it spun right up.

Re-assembled and ran the Morgan all day. Great day for a drive!

I'll order a backup pump rebuild kit this week. Looks to be ~$170USD.

Thank you!
