Answer

Assuming you do have fuel pressure to the fuel rails on the intake, it seems as though your injectors are not firing. Likely loss signal from possible failed crank sensor and less likely, cam sensor. good way to check if recieving signal would be to get a screwdriver,

put it to your ear and on the injector, and see if you can hear clicking while a friend cranks the car.

If not, your computer is not driving the injectors, and most likely a crank sensor fault.

Now to test the crank sensor (by the harmonic balancer) it must be removed, and a digital ohm (measures resistance) meter needs to be used to check for an open, if you get anything higher that 10M OHM or even OL, the sensor has failed.

Thanks

Nick.

how do you get the crank senser out

Accepted Answer

it is a two wire sensor located on the front cover, should be a black connector sticking out, may have to get underneath to locate it. Only one bolt holds it in place, it is either a eight (5/16 socket will work) or ten mm. bolt.
