Hi all, some will know I've just had my engine rebuilt also change turbo and manifold spec.

My problem is since the car has been on the road it won't start once warm?

It just cranks over and over but won't fire, the strange thing is it will bump start. I've changed crank sensor and cam sensor, I've tried running the car with the coolant temp sensor unplugged but still no joy. Now I can't remember before but now my fuel rail is pretty hot and I'm wondering if the fuel is evaporating but why would it bump start.

I want to get the car back to mad for a new mapping session but would rather try get this issue sorted first.

So any ideas please

 

how's the fuel system hooked up? could it be vapour locking the fuel rail?

 

Is the starter motor winding over quick enough once warmed up?
I know some cars wont fire if there not cranking over quick enough.
If not maybe some wiring braking down once warm?

 

That's what someone said mate, but it's the same setup I had with last engine and turbo etc. Just can't understand why it's doing it now

 

Have you sorted your 0volts on cranking as this will be it.

Mark

 

I've changed them fuse holders mark, going to pop back to Justins and plug laptop in again.

 

have you got a healthy fuel supply.

when my car is below 1/4 tank it will struggle to start from cold (but not from warm)

 

Just get the fucking thing to sheedy let m sort it for you once and for all

I'd have burt the thing out by now

 

Told you to swap me it when it needed the engine sorted

 

Pretty sure you said that about the cossie as well lol

 

Haha, well you should have listened to me then, and you should listen to me now! lol
