Car stop suddenly whilst driving
Hi !
I have a odd problem. My car has been tuned by a professional tuner (with very good reputation). This was done with HP Tuners. However, after this was done the car stops (not possible to start) suddenly whilst driving. This has happen several times.
The only thing that tells me that something is wrong is that after the car has stopped the priming time for the fuel pump when cranking is very short. Normally the fuel pump should prime the fuel pump for 2-3 seconds, now it is only doing it for less than 0.5 sek. The fuel pump does not run when cranking and therefore not starting.
If I read and down load the file from the PCM, switch off the ignition for 15 seconds as you should according to the instruction, the engine runs again .....
What I understand, the only thing that happens when reading a tune file from the PCM is some kind of reset of the PCM when disconnecting the computer/interface.
What could be wrong ? Any clue were to start to search ?
