Which model car do you have?

See the Zone Wiki troubleshooting guide:

From your other thread, you say you ran it low on fuel, so maybe you've picked up sone gunge in the bottom of the tank which is blocking the fuel hoses...

I'd check those, and maybe replace that fuel filter if it hasn't been done in ages.

its a 325i sport any tread on how to check the fuel tank and how easy is it to replace the fuel filter gona top it up with 20quid with the can any step by steps will be a big help

[Speedtouch]

Remove the fuel hose from the fuel pressure regulator (little black canister on top of the injector rail at the front of the engine), crank the engine over and see if any fuel spurts out.

Replacing fuel filter is fairly easy - it's located aft of the nearside rear wheel, but be careful not to spurt fuel in your face as you undo it; depressurise the system first by removing the fuel pump relay or Fuse 11 and running the engine until it runs out of fuel.

Check all fuel hoses for splits while you're there.

cheers speedtouch but gutted seems no luck

[Speedtouch]

What do you mean - no fuel being delivered?

In that case, check the CPS and its wiring carefully - they often get chafed through by the fanbelt pulleys.

Also try bridging the fuel pump relay contacts:

Identify and remove the Fuel Pump Relay.
With the relay removed, bridge pins 30 (red wire) and 87 (green/violet) to directly power the fuel pump. Turn on ignition, and check for fuel.

No need to turn on the ignition. Fuel pump should run as soon as the pins of the socket are bridged.

I stand corrected, however, in my defence, that was a quote from the Zone Wiki!

fuel is all good replaced the crank sensor checked and plugged all sensors in still no luck

[Speedtouch]

Have you checked for a spark at the plugs? Whip one out, lay it on the rocker cover (still connected to HT lead) and crank the engine over, and observe for a decent spark.

[danny314]

checked all good seems il have 2 drop it in to my local mech will keep you posted could it be the crankshaft it self?

[Speedtouch]

Highly unlikely to be a broken crankshaft - you'd hear horrible noises coming from the bottom end!

Have you tried spraying some brake/carb cleaner down the throttle body while cranking the engine over?

[danny314]

yep it comes a live for a second then dies out

[Speedtouch]

Sounds like you have an electrical fault of some kind. Try cleaning out and adjusting the TPS, and swapping the DME and fuel pump relays. Also check all fuses are OK.

a pal had a look and it seems someone did abit of dodge wiring before hand well 4 years back and it over crossed he did a bit of tamping and shes running thanks agein speedtouch for all the help

[Speedtouch]

Glad to hear you got it sorted in the end.

thanks agein
