Ignition timing is done through the ECU from the cam and crank sensor. How full is your tank?

[pete l]

It has 10 litres in it. all brand new too.

[Steve220]

I know this is going to sound daft, but try putting more in. Not sure why, but they seem to want loads of fuel before first start!

Send your Injectors off to be ultrasonically cleaned, well worth it.

plug leads on right , fuel pump knackered mate had same thing , same problems ..

spark plugs dead.

earth strap on engine

Have you got a picture of the engine from the front?
Are the fuel pipes the right way round? (can't remember if you can put them the wrong way round or not)
As above, more fuel should help with fuel presure build up.
On that last one, have you changed the petrol cap?

[pete l]

Ok, for me it is definitely a pressure problem. I have powered the pump direct and can hear nothing up front by the fuel rail and the return to tank pipe is dry, with the pump powered !.

[pete l]

I really don't have the money for a new pump, anyone selling one cheap ?

[pete l]

So, I've been playing around under the bonnet as they say, I powered up the petrol pump and left it running for a few minutes, cleaned a couple of sensors on the inlet manifold, removed and cleaned the crankshaft sensor and bugger me, it fired up.

 

It is running rough though, I only let it run for a couple of seconds, i'm in the basement and the exhaust fumes stink the house out.

 

I'll have to find some sort of tube to push the exhaust fumes out the door.

Thats a positive start! What I would do is get the tank filled up a bit more and put some injector cleaner in with it. Not sure what your fuel pump is doing though as it sounds like the pressure is a bit weak!

Backfire in the inlet is a lean condition, HOWEVER, check your other post regarding MPi ignition leads and coil pack, I have responded there.

 

 

hazard an educated guess that it's likely the fuel pump to me.

 

Take the tank out of the car. In a well ventilated area (outside and away from the garage, house or the car) securely fit a length of fuel hose onto the fuel supply line connection on the tank and then place the other open end into a clean bucket. Power the pump and watch the fuel flow from the hose. Slowly kink or pinch the hose  and listen to the fuel pump, its tone should notably change, and a loud hissing should be heard where you have kinked or pinched the hose, you should feel a resistance in the hose and fuel should still be flowing. If you get to the point that you have kinked or pinched the hose completely, fuel has stopped flowing and you have not experienced any of the things mentioned above, the pump is faulty. Ideally you should have a pressure gauge fitted so you can see the pressure rise as you kink or pinch the hose.

Obviously you are working with raw fuel in an open bucket and electricity on the tank, take great care and if you are unsure about anything, leave it for someone else.

Here's the video of it starting. I shut it down straight away because of fumes etc.

Once it cleared, it sounded like it was almost there!

[pete l]

Can't wait to get the exhaust pointing outside so I can really start her up. 

 

Kind of exciting !

[Steve220]

C'mon Pete, sort it out!! lol
