2007 159 1.9 JTDM Poor HOT (now cold) Starting problem
My 2007 159 1.9 JTDm has a problem starting, to tell the story in full the car broke down and failed to start a week ago, AA diagnosed starter motor failure as it clicks to engage but did not crank. I had no signs that it was failing, it just left me in a car park one evening.
Anyway I've now fitted a new starter and it cranks it but it's really bad at starting, I have to press the accelerator and hold the start button until it picks up over 1krpm. If I don't do these things it just cranks over, splutters and fires a bit but then stalls. This is why I have to hold the start button longer to keep it turning past the initial firing and pressing the throttle helps once it's turning to pick up the revs so it'll actually idle.
There are no fault codes, and the issue is the same on cold start or re-starting with a hot engine.
I changed the starter myself and that was a pig of a job, I've tried to check if I may have dislodged something or failed to connect something back up.
I'm checking with the supplier of the starter to ensure I got the correct one. EGR is blanked off and no DPF. The engine runs fine when it's going and idles as it should it's just a pig to start at the moment.
I don't think it's glow plug related as the issue is the same regardless of engine temp. I'm really stumped as to what it can be and it's getting quite embarrassing having to attempt to start the car 3 or 4 times in some instances, for example it did it 3 times over the weekend, at the tip and at the fuel station, only stopped for minutes but unless it catches the first time and I hold the starter engaged to keep it turning and then a bit of throttle to get it to idle.
Any help advice appreciated, the battery was new less than a year ago and is a Bosch S4 so not a cheap one, it also proceeds to crank the engine 4-5 times repeatedly with no sign of slowing, but i'll consider anything at this point.
