Thread: Non start D2 V8

Does the cranking [normally] register on the dash tacho?
and will that be from your sensor SF?

You'd think I'd have noticed before asking wouldnt you,,,

Don't recall it showing on tacho Pete.

Cheers

dodgy battery leads and car now won't start ...

Dould it be immobilised?

icar thing says alarm problem?
is the small red led lower/middle of the dash flashing(I think it flashes rapidly)?

Although in saying that, I think that if it gets immobilised, it doesn't crank at all.
Can't remember now, it was a while back when brothers TD5 had the problem which turned out to be a battery that was on the way out(low voltage).

Do you have the EKA code?

Does the nanocom access the BCU info area?

Another thing to check for(coz it's come up a few times) is the battery earth strap.
It should of the type that goes from battery neg terminal, to the body via a metal bracket a short length from the terminal .. and then continues on to the engine(on a bracket at the drivers side front corner).
make sure this is all in good nik too.

I am wondering if the fuel system may need to have the air bled out of it, As I haven't had to change my fuel pump on my D2a V8 I don't know if this needs to be done on "lardy's" V8 as he said that he has replaced the fuel pump there may still be air in the system.
Does the fuel system need to be bled on the 4l V8's Just wondering if this may be the problem?

Thor injection is one pipe only to the injectors but the injectors themselves do an adequate job of bleeding air from the rail. It would just run roughly for a while before smoothing out. You can in any case find the Schrader valve on the fuel rail (somewhere down the back of the manifold) and check for fuel pressure. It can be reached with your fingers, close to the rear most inlet runners.

Thanks for that

Indeed I always believed that when you turn the ignition on you see the rev counter 'flick up' prior to starting .....it don't.

I have replaced the fuel pump on a d2 v8 and no bleed was required. I know others who did it and no bleed.
