Thanks for this need to remove the lower inlet gasket for change and was worried about moving fuel rail

[@azwinndinimaumela3158]

please help, i changed the spark plug from cheap spares part shop, and the car did not start, i though maybe it was becasue the car has been parked for too long I tried to jump start it, still it did not start, I then went to the agent and bought what I asumed is the original as I bought the spark plug from the agent but the car wouldn't start, when i check on the cluster i see the is massge saying in water fuel.I have opened the fuel pressure sensor and water came out on the fuel rail by the injectoer and bit of petroll still the car does not start,, please i also changed the oil and all the service kits. the das board does come on but not cranking, the car does ot show any sign .i also checked the runner and fuse to see if are not faulty but all was good. i replaced the cranking runner fuse thinking it was faulty,, any idea why?

If the injectors go bad what symptoms would you get.trying to eliminate some judder I've got.

[@lukethomas1364]

A judder isn’t just injector related bare that in mind mate could be spark could could be a sensor not allowing correct pressure of fuel in and injector like u say or an ecu fault

Nice Video Mate!, Which Intake Pipe is this, its very behind the valve cover

[@gregoryelgood]

It's a ram Air alloy pipe, nor sure they do them any more.

Anyone here running dreamscience mod x rs on 550cc injectors. Dreamscience recommended 440cc on that map but I got the car with 550cc in and I'm not paying to downgrade lol

[@gregoryelgood]

I'm not 100% sure but can you not select the injector size on the dreamscience?
