The engine starts and then stops after 2 to 3 seconds and has fault codes of high temp exhaust sensors 1 and 2 but I cannot locate these sensors the dealer worked on this car before when it shorted the wiring on the ECM and they change the but not the wiring harness and said they cannot supply the harness any more...but maybe the harness is still ok as it is because the engine starts but it just stops after 2 to 3 seconds every time but could not keep it running

I have 2007 chevrolet captiva ltz diesel car was decated but the exhaust was never replaced with a straight pipe car has a hard start and takes too much juice we diagnostic it and the code mentioned Maf range performance we changed it its still doing the same thing

I have a 2013 capiva 2.4lt ecotec. 65litre tank and i only get 350km on a full tank. Ive removed the cat with a straight pipe, cleaned off the 2 O2 oxygen sensors, the maf sensor cleaned, added injector cleaner to fuel, and replaced both intake and exhaust solenoids and still blowing black smoke, black soot spots on my tail gate, a little rough idle but not much, its still burning up too much fuel, leads me to think its the injectors over fueling?
