2000 volvo c70 79000 miles crancks dies right after dying, fuel pressure in the rail is good, the injectors pulsate only 1-2 times then stops, i checked the electricity coming to injectors with a noid light and i noticed that it starts with strong light then the light gets dimmer and dies i would say at the 3rd cycle of the same injector. any idea what may be the cause?
thank you guys in advance

 

possible immobilizer problem try another key

 

i have only one key, I changed the antenna and no change, car didn't run, all the injectors wiring have positive in them, but the fact that the noid is giving light then dying i'm assuming the ecm is working and a possibly a sensor is not doing it's function, it has a brand new crankshaft sensor,when i unplugged it there no lighton thenoids at all, do you think the camshaft sensor has anything to do with it?or what other possibilities, like ecm fault,...
than you very much.
