Hey folks, after searching around previous threads i've come to the conclusion that it could be the PTU, however I just want to see what others think, as it's very possible I'm completely wrong :wack:

 

Here's the story, about 3 weeks ago I gave the car a good clean polish etc and when I went to move it afterwards it wouldn't start, it was turning over but wouldn't fire up, seeing as it was late, I said f**k it! and went to bed, next day I came out and it started no prob but spat out some black water out of the right exhaust. No problems since then, until Tuesday, I left my light on all day :smash: :smash: needless to say the battery was dead, got a jump and away i went no bother. Yesterday morning off to work again no bother. Then last night leaving work and it wont start, same as the last time, it's turning over but wont fire up :( and still no joy this morning, also the check engine light is on.

 

Any ideas folks? much appreciated.

Its possible it could be the PTU, is the car a series1? The PTU's on series 1 cars are prone to playing up, a series2 PTU is more reliable if you can get hold of one all the better. First of all do an ECU check, see if any codes come up. If that shows no faults take the connectors off both sides of the PTU and give them a good clean of any of the green shite that plays havoc with the connectors, see if that helps. If still no joy try the CAS take it out and give it a spin, there is plenty of posts about this, if you hear clicking then you know the injectors are working, so more than likely fault on ignition side. Good luck

Thanks for that, it's a series 1 alright, so you've confirmed pretty much what I thought, I'll have a look at the CAS too just to make sure it is on the ignition side, cheers.

try taking off the connectors to the ptu, cas, maf and cleaning them all

 

old crispy wiring is a proper headache
