got the engine back in the cossie but having a few problems
no live to fuel pump but the car runs but shit put a live to the fuel pump and it cuts out ?
when it is running its over fueling other thing is ive broke the map sensor does the map sensor have any thing to do with fueling or is it just manifold pressure
thanx in advance

MrC

If you've broke your map sensor that's why it's overfueling, it plays a big part in fuel metering to the engine.

A broken map sensor will give all kinds of problems.

Maybe the pump primes as I'm lead to believe it does this from the relay.

Then after that needs a live (which you don't have) so therefore is running until the pressure in the lines drops and starves of fuel......?

MrC

Sounds like its badly overfueling, when you connect up the pump it's probably flooding the engine, that's why it cuts off, does it stink of fuel when it cuts out??

maybe where you have drilled into it you have damaged the internal circuit of the map sensor causing your voltage problems

the pumps not priming at all but the car will run but badly and yes theres a strong smell of petrol
will try and get a map sensor tomorow and see if i can find the problem with the pump live carnt see the live been down to the map sensor tho
i dont get how it runs with the fuel pump not working

could it maybe gravity feed ?
