Coincidence or not, fuel pump and relay issue.

Hi,

Took the griffith out a few days ago, went down one of the canyons in our fabulous roads……. and the car died instantly.

Fuel pump would not prime, turned out the fuel pump seized and the relay also stopped.

Would the fuel pump seizing knock out the relay, or just a coincidence?

New fuel pump fitted and a couple of relays and all is good again.

Our cars have to be road worthy, surely the roads should be car worthy…

Maybe the increased current drawn by the faulty pump caused an issue with the ageing contacts in the relay, not uncommon.
Always a good idea to keep some spare ones around.

My thoughts exactly, the relays looked original 30 years old, as was the pump.

I struggle to remember the last time I replaced a failed relay in any of my cars!
It’s a common issue on the Tvrs possibly as you say because most are original and tired.
Just make sure they are the right ones as the contact configuration can be different but buying from a reputable source this shouldn’t happen.
