I lol'd when I saw that you have flashed this car 43 times. I have nothing to add to your issue though  Yeah, but I'm not even close to finishing my tune (only VVT experimenting took 10 flashes), so there will be at least 20 more flashes...  |

And your a 100% its a tune related issue i mean can you confirm a rpm signal on crank and fuel press. I am not a tune guy the ppl that help me are already here but I am a mechanical guy.

Well, I never was 100% sure it was a tune problem, I was just suspecting I could have done something wrong and now I see no logic to say it's a tune problem. As to the hardware side, I already had the RPM sensor error code (and EPC lit) appear some times and the car was hard to start on these (rare) occasions. So I surely need to change that sensor. When I tried to start the car today I saw the rpm needle jumping from 0 to approx. 300rpm while cranking - I'm not sure if this means my RPM sensor is OK - I'm going to change it anyways. As to the fuel pump I can hear it building pressure when I put the ignition to ON. In a few words, I need to change the RPM sensor and if the car won't start then I'll look at the fuel pump. Correct me if I'm doing it the wrong way. |

Well rpm signal means your crank sensor is good. I would take a old spark plug and pull a coil out plug it in and see if you have spark. If you do then if you have carb cleen spray it in a vacuum hose on your intake while cranking after you plug your coil back in that is |

Dumb thought, but might be worth checking you still have a cambelt.

Thanks for the advice, I'll do that next. Actually, that was the first thing I was about to do, but I thought what is the chance more than one coil or spark plug to fail while the car was parked... Anyway, I'll try it on all coils. |

It would really be a surprise if I hadn't I would never have though about that, I'll check that too. |

I need to mention I hear a repeating clicking sound when cranking (just like a relay constantly switching On-Off) from the are that fuses are located (to the left of steering wheel).
I was also wondering - would I have these symptoms with a faulty MAF?

it is in the e2p Yes, but if I'm right nefmoto flasher changes eeprom content... I'm not sure other flashers change it too. |

It definitely writes a tuner tag and increments the flash counter, I've seen other tools add their own tag too. I was under the impression that the flash counter was built into the ECU, not a number that nef actively incremented. $ python eepromtool.py 95040_nostart.bin

Should I have any concerns about that part? P.S. RPM sensor is on its way. |

Only if you have P1681. |

I changed the RPM sensor today and car started. Problem solved.
Thanks to everyone for the help.
