Car won't start

From who? I have about 7000 of them at present.

From me, Dmitri. Just sent two seconds ago re: Chip set.

Hehe, you typed "you got PM" before you actually sent PM, alright now

Which exact code do you get for G28, copy & paste please.
MAF has nothing to do with starting the engine, it's not used until the engine is running.

My bet is that the fuel pump has packed in, but might be wrong.

Here is the code that came up.

00513 - Engine Speed Sensor (G28)

Here is the code that came up.
00513 - Engine Speed Sensor (G28)

You will always get that code when the codes are pulled on an engine that is not rotating/running. Usually the G28 code is a false positive and can be ignored. Certainly don't run out and buy a new sensor until all other avenues have been explored, e.g. testing and/or replacing your fuel pump in this case.

Will check fuel pump when iv got time as it seems the most logical having no codes present, iv just gone and bought the hall sender from Tps £159.12 with my discount So that's most of the sensors, pipes and plastic bits bought now just need to fit them all.

I seriously don't understand why people, who are not in a desparate need for a G40 Cam Position Hall Sender, don't buy just the sender for US$10 (plus shipping) from EFI Express. To buy the factory sender on the bracket for significant money and then go , makes me shake my head (sorry).

It's not like this should be a surprise to anyone here. There is a sticky about this and there have been one or two group buys in the past.

Take it back and I'll send you the spare sensor unit that I have.

Or just buy one from Bosch, mounted on the bracket for £58

Here is the code that came up.

00513 - Engine Speed Sensor (G28)

There is a secondary code with it as well, which is important.

The hall sensor is always diagnosed by the ECU, and if there is no fault code for that then it's a waste of time and money replacing it.

Anyway, I'll sit back and watch for a bit.

Well checked the fuel feed this morning nothing coming through to the rail. So i stripped out the tank replaced with a pump that was working when i took it out of a 3b i broke and no joy wondering now if it could be the relay if so where is it situated. And took the advice from some peeps on here and cancelled the order for hall sender.

Its relay 208 in the fuse box. I was able to test the fuel pump when the cover came off the relay itself pulled off. I was able to press the contacts and I hear the pump work.

[bilko0795]

Just replaced the relay with a spare i had still nothing.

[bilko0795]

I have just tested the pumps and they are both working and the car started run for 20 seconds and then died, tried starting it again no joy but it's now trying to start where as before it just turned over with the odd splutter. So it's fuel related seems to be the problem. I have checked for power to the injectors all ok. I have also noticed a hissing sound coming from the back of engine bay like if it's leaking air is this normal.

It still might be the Hall Sender but at least now you won't be spending GBP 158 for one. I am late to the party on the fuel pump relay location but here is some info that might (or might not help, e.g. the 208 FP relay has been replaced by a 372 FP relay when/if you need a new one):

Pumps? What do you mean pumps? Normally there is just one pump. What is your fuel pump situation? Aftermarket set-up?

You need to do the Fuel Pump Test as suggested in this post:
