hi, i have an 03 vectra 20dti, changed fuel filter and car wouldnt start,give it a tow and it started within 1/2 mile. took it for a good run, switched it off when i came back and it wont start again. will only start with a tow and runs fine.
got it plugged in and the following codes showed;
p0115 coolantant temperature sensor
p0149 injection timing control circuit
p0606 control unit
dont know if any of these codes have anything to do with the non start issue. any ideas welcome
