hello im new to this site, i have a 07 punto 1.3 diesel, it started and drove but on driving the glow plug light flashed. go to where i needed to go but when i got back to the car i turned the ignition on but no glow plug light came on and didn't start also noticed the fuel pump wasn't humming, i briefly googled a way to get it started so i did that it said to disconnect battery then turn ignition on the connect battery and then i got it running. once got it home i used a friends scanner there was no codes what so everso if any one could help me it would be great.
