The injectors are not pulsing. but when i put fuel in the plenum chamber she fires for a bit. And yeh i have got the same ratio in the rear as in the front.

I would say it has been sitting for a fair while, I thought that the Ecu may not be firing the pulses to the injectors but I hadn't thought that the injectors and rail may be blocked with yellow gunk. what's the best way to approach cleaning the gunk out? can you get the injectors etc out without taking off the manifold?

Cheers for your help guys , Clive
