Fiat Grande Punto 1.3MJD6F3.PI/HW04P/3641-PI90 75hp no start after crash
Hi there, I have a 2009 Fiat Grande Punto which was involved in an accident, resetted the airbag computer, rearmed the FIS, no errors on the ECU neither on the BSI, but the car won't start, the fuel pump does not work, checked the fuses and wirings, all ok. Could you send me a clean dump of the eeprom? the ecu is a MJD6F3.PI/HW04P/3641-PI90
G PUNTO 75hp UEGO SM2 7gcsdpa9j. Dump of the eeprom ST95320 in attach. Thanks a million!

Actually this model didn't have fuel inertia switch fitted, to re-arm the FIS I followed the "ignition on, indicator right, left, right, left, ignition off" procedure. The problem was in the ecu eeprom dump, which blocks the fuel pump relay and does not command the injectors.Thanks and credits to 3in1san , who sent me a virgin dump of the st95320, the car started, after I only had to re-write the injector codes. Thanks again, mate, and thank you for your replies!

Fellow friends on DK, all posts with st95320_virgin, including mine, are rubbish, because the mjd6f3 ecu keeps the keys in the eeprom and, if you will try to write a "virgin eeprom solution" exists a great risk that your ecu flash corrupts and the car won't be able to communicate with the engine control unit anymore. Back then I fell in the same trap, my car started, but only once, so I thought it was an ecu hardware problem. I bought a brand new second hand ecu, wrote the "virgin eeprom solution"+the original flash, and guess what, the same situation, not even communication with the engine control unit.
So, I kept the original eeprom, search a Flash file from a car that wasn't involved in an accident, wrote it, and voila, problem solved. Believe me, it is 100% tested, my customer still uses his Fiat. I know I am a junior member and my words are not so, let's say, so reliable
, but if you will search through posts with people who actually wrote "the virgin eeprom solution", you will see that are a few that weren't able to communicate anymore with the engine control unit. So, original eeprom+a flash from a car that wasn't involved in an accident it is the real solution.
