redtop nova help!!!

[kane]

i have just finished building my nova and when i go to start it it takes 3 goes to start. doesn't matter if the engine is hot or cold. and when i accelerate it goes then hesetates and then goes agen. sorry foe the poor discription but does anyone have any ideas what it could be please.

[let_nova]

poor fuel pump?
did you service the engine?
plugs
leads etc?

[Southie]

Bad earths maybe are they all attached okay?
Have you wired up the eml light?
Was the engine running okay before you installed it?

[Adam]

What shell is it? Did it used to be a SPI? Have you fitted a proper fuel pump

[kane]

its had new plugs and the leads off my other redtop.

the shell was a 1.2 spin so i think it was a spi and all earths are on ok.

[kane]

what fuel pump would you recomend

[Adam]

Have you changed the fuel pump or is it still running the standard one?

If so, theres your problem.

You need a mpi pump off a mpi mk3 astra

[kane]

fuel pump is located underneath the rear seat bench isn't it

[Adam]

Yep, in top of the fuel tank

[kane]

ok sound. looks like a trip to the scrap yard then.

[kane]

would a vectra 1.8 one work.

[Adam]

Unbolt the complete housing out the fuel tank on a mk3 astra(make sure its a mpi car/engine model), and bolt it straight into your nova tank

[let_nova]

to answer yes a vectra intank pump would do.

[kane]

i have tried plugs, leeds, new fuel pump and its still the same. could it be a sensor and if so any ideas what one??

[Nobby]

afm?

[Jon_nova1]

it would start fine with the afm disconnected

throttle position sensor? does it smell of fuel? does it not rev at all?

[Graeme]

I say the spi pump is still in there

[Adam]

Have you fitted a mpi metal pump?

[kane]

i have put a mk3 astra mpi fuel pump in. its not the airflow meter because i have used the airpipe with the afm off my other car which was running fine.

it does rev but when you go to start in 1st gear it kills all power and tries to cut out and mis fires when accelerated hard.
