Have you ever seen or heard it run?

If so, what noise did it make when it died?

Actually the link is www.poweralfa.com. Pretty good site. A pity they do not have any bodykits for the 155 there. But the wheels are nice. Maybe I travel to England this summer... :D

Hi Pete
Here's a hint.
On thet bracket(behind battery) there are some relays.
Check them out with an ohm meter or simply chenge them. One of them is responsabil for ignition(?) the othere is for fuel pump.I just fix this second one (WRINX helped me to find it)
Simpli it was a bed contact.

some fuel pumps only prime when engine is turning over.

Assuming it WAS working when it was parked, I'd check the obvious.

Bung some fresh petrol in the tank, dry out all the electrical connectors (especially coil and ignition) and check that the injectors and coil have a live feed to them.

Then try starting it using the biggest battery you can connect to the ***** and see if the injectors and sparks are doing their thing. As my bro' would say, "you can ignite anything if the spark is big enough".

A duff TDC sensor could disable both the ignition and injection, even if the coil and injector live feeds are okay but this is a longer shot - it WAS running after all.

More likely to be cobwebs in the system...

My 8v fuel pump primes with the ignition on. You can actually hear it from the front seats but if you put your head in the boot and ask someone to switch on the ignition then you should easily hear it.

Pete, forget relays!!!
If you don’t hear the pump as working so probably he isn’t .
So take out he’s connector (you’ll find it below a “black” plastic cover in “luggage” compartment near back seet)
Then look for two wires long enough from battery till back .Connect them first on battery then (take care for short circuit) just try to put on pump free connectors He should work, and you should hear. If not you have to take out the pump and probably look for replacement.
Take care!!! don’t put the wires on fuel level meter. This is also there
