Check for power on the red and yellow wires.

Get it on a high level, pro grade scan tool and check long term and short term fuel trim.

Make sure all the tires are correctly inflated, no brakes binding and drive light footed.

car i know a website that has every info on all vehicles and vehicle problems,
with their solution In detail.. it's www.reliable-store.com

you have to vent the air in the injection pump crack the injector pipes and crank the engine till fuel come out then re secure the pipes it will start then

check the wiring to the retarder and retarder controls ( accelerator sensor --brake sensor etc ) finally have the unit inspected by a service centre dealer.

may be you should make a diagnostic and you can do it in a garage or you can do it by yourself if you want to do it by yourself you need some tools and you can find some good ones here:http://www.xcardiag.com/
