spark and fuel but no start
i have a 1996 c220 gasoline powered that recently failed.
i have spark and fuel pressure but no pulse in the injectors.
Cam and crank sensors were tested and are in good condition, overload tension relay is good too.
The scanner says " IFZ COMMUNICATION " so i bought a replacement with matching numbers but still no start.
This is an ifrared alarm equiped car, the key has no chip on it, in fact, electrinics inside the key fob are no longer there since they stopped working.a couple of years ago, so i dont use the alarm. i have an after market kit to open and lock the doors.
tha car is my daily driver and it suddenly failed-
here is a picture of the module. i hope you can help me. Regards from mexico.
