Standard management use both Crank position and Cam position and plots a graph to ensure they're in the correct position relative to one another... We call this "synchronisation".
The engine management then can see what "advance" the Dephaser pulley is pulling and adjust the timing accordingly...
Thanks for the heads up Mike I will deffo give that a look. I was going to do an in line pressure test at the rail to on Monday but I think I'll check the tank to.
Yeah its very true and becoming more common. Even I've had a guy from Liverpool call regarding a car I've worked on before asking for duplicates because he didn't believe the clutch had been done... He was right, I'd never seen the car before.
This was a car that sold on eBay of all places!
I've got a 1.4 16v Meg II come in today with zero throttle response, just splutter splutter cough cough. Ignition and injection functioning fine on the Scope, compression is balanced and everything looks fine in CLIP but it just will not rev freely. A previous garage has thrown coils, plugs...
You've seen on screen fuel pressure drop.
You've also done a leak off test which shows conclusively that Inj 2 is returning more fuel that it should
What more proof are you looking for? Injector is ballsed and needs replacing/refurbishing... the end
Sounds like the pump itself and the control circuit needs testing to me.
Start by giving the pump a direct +12v and earth with a power probe and see if it runs. Then test the cars circuit as I bet it's a wiring issue.
Not an obvious one I don't think, did you run the Trophy James? Probably something electrical like an H02 or CTS playing up here as it's not far off the low to mid 160's they normally achieve.
It's so proper that it's churning out generic "P" codes with little explanation.
You're in Derby which is stupidly close to us. It could be wiring, could be the sensor... have you actually checked the wheel speed parameters?
Sounds right on the tooth count but I'd say your next call should be to confirm the fault on a proper code reader. P codes don't mean diddly to me I'm afraid so cannot offer any help with them.
