My Mazda 2 2019 skyactive 1.5 g started cutting out randomly when hot , now does not start even cold. Due to no error codes, the problem was hard to find. at engine off ignition on, I found pressure of 29900 kpa on the fuel rail. the fuel pump would not prime. I took the fuel injection relay and fuel pump relay out, then I took the sensor out of the rail. left it connected and tested it again, no pressure in rail and reading at 29900 still. reconnected everything, but this time I plugged the sensor out. then fuel pump primes and car starts, but obviously over fueling . reconnect sensor and back to same symptoms. so the fuel rail sensor is faulty without a doubt. Now I am struggling to find a replacement Bosch 0 261 545 155. the dealer wants to sell the complete rail . anywhere I can find suitable replacement for this sensor?
Fuel rail pressure sensor stuck at high with now error codes.
