Fuel pump primes continously

Hi, I upload the calibration and ecu shows that I'm online and datalog sensor readings but map sensor read 4600 kps and fuel pump primes in every 2-3 seconds. Is there someone who have this problem before?

Note: map sensor is stock and it shows 4600kpa but sometime for just a second it shows 100kpa which is correct at half switch

What is the serial number on the s300 inside the ECU?

From Help, About, what is the version of software you are using?

Serial number on the s300 is 32589 and the software that I'm using is the latest version 2.4.4.0. I tuned this car 1 month ago without a problem after that I starts to make this problem and car doesn't start.

I check the car with an other p28+s300 andits working great after that I check the s300(32589) with an other chipped p28 and works great again. So, I think problem is in the p28, do you advise some resistor or transistor to check if its ok or not?

Thanks.

The best thing to do would be to get a working ECU and use that. Trying to repair an ECU is usually more time intensive and costly than just buying a working one.
