1998 156 2.5 V6 Fails to start

Hi there, I'm new to the forum.

I'm helping a mate fix his Alfa which refuses to start.

It's a fuel issue.

So far I have fitted a new fuel pump and fuel pump relay. All fuses are fine (engine bay and glovebox).

When cranking the engine the fuel guage jumps from full to empty back and forth rapidly - I'm assuming this is a wiring issue somewhere? (The fuel tank is full of fuel).

I got it to run for about 15mins the other day by tapping the relays in the engine bay, but it now will not restart.

Does anyone have any suggestions?

Many thanks

have you checked to make sure that there is definately power to the fuel pump and that there is fuel pressure reaching the rails okay?

also have you checked the ECU to see if there are any fault codes logged? could well be a dicky sensor that won't allow engine to fire.

sounds like a possible poor earth somewhere. also be aware that low or dead/dying batteries cause all sorts of issues in alfas, so dont be amazed if its a flat battery making the fuel gauge go bonkers, give that a charge and see what happens.

there is also a fuel cut of switch underneath the front passenger seat which is supposed to be triggered in crash / emergancy situations. its a rather unassuming black plastic box slap bang in the middle with a rubber round bit on top, can always try giving that a press to reset it.

a friend of mine couldn't get his TS started a couple of months ago and couldn't for the life of it work out why, think his wife had kicked the fuel cut off by accident and triggered that.

I doubt its the case here but could be worth a press.
