Running Rough, Starting & Power Loss
Hi I was driving along the other day and stopped at trafic lights, the car stalled and wouldn't start. There is a spark at the plugs but no power at injectors. Ive changed Injector relay and air sensor, and have looked for signs of a blown fuse.
I unplugged the two terminals on fuel pump and have no power there either although when I turn ignition on there is a clicking sound that comes from pump but no other sounds and no fuel from pipe? I have replaced the Cam sensor too. It's getting pricey now can someone help?

Woops!blank page,sorry 'bout that.
So,no power to the injectors?should be 12V as soon as the keys on.
Start working your way back along the wiring harness from the injector plug until you find the lost V.
I don't use a multimeter for these tests,not enough draw,use a test lamp,you can cobble one together from an old indicator bulb/holder.
earth one lead and use the other to probe back along the injection wiring until it lights. straight forward,no code reading,old school.
