July 11, 201114 yr OK...any sugguestions would be gratefully recieved... Please bear in mind I am not a mechanic or a technical expert. As I look at the engine, the middle cylinder on the left hand bank is not firing. So far I have... Swapped coil packs around and the same cylinder still doesn't fire. Swapped spark plugs around and the fault remains on the same cylinder Tested the resistance on the injector..it's 12.7 Ohms Tested the resistance on the coil pack..it's 0.7 Ohms Tested the voltage on the injector feed...it's 13.34 Volts Tested the voltage on the coil pack feed...it's 14.06 Volts (The coil pack connectors are brand new) The engine was replaced a couple of weeks ago and has been running like a dream until today. Any ideas would be very welcome... Thanks in anticipation...
July 11, 201114 yr seems a little low that ohming. anyways tcheck taht you definatly have a spark at the plug by grounding it to the plenum, dont touch the engine when you do this or use a spark detector only costa few quid. then check the injector is pulsing with the aid if a long screw driver, you should hear the same rhmum on each injector. i would likly say that its either a faulty connection or a faulty injector.
July 11, 201114 yr Author You're right on the coil pack resistance...checked it again and it's reading 0.9 Ohms (my mistake). Will check the injectors pulsing and post again. Thanks.
July 11, 201114 yr Author Just did the screwdriver test and the injector appears to be pulsing the same as the others...
July 11, 201114 yr Check the connections on your PTU. A corroded connection was the cause of a missfire I had.
July 11, 201114 yr Author Steams you are the best!...thanks...the PTU connector had popped off at one end...all sorted. Thanks so much.
