Question about Cars & Trucks
May have clogged injectors. small particles clog injectors and sears has a method of blowing out the injectors and adding some heavy duty cleaners to the fuel system that loosen these obstructions up and allows them to greatly improve performance. After they did mine my mitsubishi ran sloppy and misfired. I took her on the highway and kicked her so to speak a few times. a few pops later it broke loose and ran awesome again.

The crank sensor is what pulses the ijectors,and makes the spark,so I would start at the crank sensor.Let me know how you come out.Check for any blown fuses also.Ecm fuse would cause this,but it may be called anything ,so check all fuses.

I know you say that you have checked pressures but incase you didn't know, there are 3 pumps on the car.
In tank = 1 bar upto an inline pump by the battery which increases to 3 bar then to the one on the engine that tops 2000 bar
The one by the battery + the intank one are VERY common to fail.
Other thing to check is that the pressure sensor on the rail is reading correctly.
Does it have any stored data? If no codes the it would be best to get it on some decent equipment that reads live data like Bosch KTS etc
Are you in the UK?

SOURCE: fuel injectors wont open, fuel
Hello! I just read your second post...I sent a solution from information in the first post not knowing there was a second...
The culprit is the Manifold Absolute Pressure (MAP) sensor...
It is called the "fuel boss"...Loss of signal will not allow injectors to fire...Crank the engine...With the connector in place you should read greater than 1 volt...No voltage out of MAP...It is defective...Cost is around $60...
