Still can't believe our cars sound so different when starting

[Captain Jack]

Well mine's f#$&ed, so that explains it.

.....at least yours starts.

[dave406]

Have any trouble this evening

[steve_earwig]

That's better, thanks

Whuh? It's dead?

[Captain Jack]

Whuh? It's dead?

No, still alive - though took a good few turns this morning at +7C to get it going. Obviously, it will be fine for the rest of the day.

PP2000 is out for delivery now, but I won't be home till late tonight so won't play with it till tomorrow morning.

Ah. I thought for a moment there that the problem had manifested itself in a more apparent manner (as my dad would say) so you'd be looking for a definite fault, rather than suspecting everything.

Good luck with PP!

so won't play with it till tomorrow morning.

Can you frig it up to give you live data whilst cranking tomorrow morning? as I think this is what you'd need to see.

Yep, that's exactly what I was thinking. Cranking it now won't tell me anything as it will start within a few turns.

Ooooookay - got PP2000 yesterday and got it installed after some helpful YouTube guides. Why can't sellers supply proper instructions?!

Anyway... connected to the car and read the ECU. Result: no faults found Balls. I was really hoping it would tell me something.

So then went to live parameters thing and started cranking the engine from cold. Chug-chug-chug-chug.. not starting. RPM was reading between 160 and 200-something and fuel pressure - zero. Now, as it was the first time with live measurements, I wasn't sure whether it's a communication fault or there really was no fuel pressure at all. After 10 seconds of cranking - it burst into life. Fuel pressure - 298 bars. Hmm...

I made a recording of the live parameters but this after the engine started the first time. So, it's a bit moot but ... I'd like an opinion on injector readings at 1 minute into the video. Injector 1 seems to be correcting up to around 2 mm/stroke whereas others are -0.something. Could it be that a leaky injector is leaking too much fuel back to the tank during cranking and not building up pressure? Hence quite a bit of cranking is required in the morning when the battery is rotating the starter somewhat lazier to build up pressure?

Happily, I have a spare injector lying in the garage somewhere that I bought when I was trying to sort out my rattle issues, so I could replace it just to see. I guess I should do a leak-off test but it's bloody miserable and cold outside and I have no desire to do this today. Monday/Tuesday will be my first opportunity to do this. In the meantime, would sticking some injector cleaner in the tank/fuel filter be worth trying?

Let's hope the injector isn't seized in the head, eh?

I hope it goes well mate my pp2000 is going back

[Captain Jack]

Yes, Chris, not sure why your PP2000 wouldn't read the ECU. Once I installed PP2000 and Lexia software, it had no problems.

I would try reinstalling the drivers/software... maybe something didn't get installed correctly?
