Hi guys. My zed hasnt been regoed for 8 years but i did used to take it around the block every couple of months. It has sat for about 10 months and when i last started it it sounded like it was running in 5, went to go have a play with it tonight and no fire on any coils but i have injector pulse. Have no codes when i do diagnostic comes in at 55. Coukd this be ptu as is a 1990 model and looks to be original. Does cas control spark?
If it is a ptu i have ptu's available, units come with 6 months free warranty/guarantee, so you know your money's good and she's backed up to keep rollin : )
"Coukd this be ptu as is a 1990 model and looks to be original." Yes, it is possible, however could be something else as well. "Does cas control spark?" The CAS monitors engine speed & piston position & sends signals to the ECU to control fuel injection, ignition timing & other functions. Fault code #11 would indicate something amiss with the CAS circuitry & you reckon you have injector pulse which is controlled by the CAS.
