They do follow OBD standards... it's just that OBD is only standardized for codes below P1000I keep saying this over and over - It is a waste of time trying to do most diagnostics on Alfa Romeos unless you are using Alfa Romeo specific diagnostic software, as Alfa Romeo does not always use the standard OBD II codes for faults. For example code P-XXYZ on the standard OBD list will describe the fault as something to do with Part A, Alfa Romeo will give the description to do with something completely different.
yes but you dismissed my advice:I went ahead and replaced the High pressure Fuel pump with a new one this afternoon. I am not sure how to proceed now. Is there a mechanic here that can tell me how to proceed.
when the car stalls, can you get an rpm reading during cranking? I'm suspecting your tdc sensor... they tend to fail when hot and work again when cold.
Hello all, when I drive my car for half an hour or so and turn it off, and try to start it up after 10 minutes it would crank but would not start. Also, if I let the car idle in the garage for about 40 minutes it would start to misfire and stall. I scanned it for codes and got P2292-21 which is for the Fuel injection pressure sensor part number: 55253502 ( Bosch) located on the fuel injectors rail. I went ahead and replaced it. Unfortunately, the issue persists. A few months back I discovered when I disconnect the Air mass flow sensor the car would start right away so I went ahead a replaced it too but no luck. Lately, I've been disconnecting the engine coolant temperature sensor part number: 55203964 every time it happens just so I can start it back up. I don't wanna go ahead and replace and find out that it's functioning properly. I would really appreciate it if someone can direct me towards the solution to my issue.
