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
