***Warning*** - Evo X Fuel Pump Relay

Hi,

I know alot of people are aware of the issue of faulty Evo X Fuel pump relay's but the last 3 cars I have had on the dyno all have had a faulty original one fitted.

The cars come in and they are generally driving fine but when we a power run there is nowhere near enough fuel going in.

The AFR should be under approx. 12 AFR when on full throttle, but with a faulty relay they barely get under 14 AFR which causes massive temperatures in the engine.

The relays are cheap enough and they can be changed in less than a minute, they are available from your local dealer.

I know this sounds like scaremongering but there is no way you will see the issue without either having a fueling check or an engine failure.

The part number is MR122409

And here is a picture of where it is located

Good thread and posting Ant, highlighting this again as not everybody knows.

Thankfully I have changed mine and I also did my Brother's X too as he wouldn't have known since he is not on here.

Fitted the blue Omron relays.

As a temporary fix you can swap your headlight (green) relay with the fuel pump (black relay) as they are a lot more robust and last longer.

Hi Ant,
I've ordered some Depo lights from you, any chance I could get one of these relays at the same time please? I can just forward via PayPal or give you a call?
Cheers
