its jumped off another fuse in the box on the back of the fuse board. Its a shite set up.
The relays are beside the fuses are they not. |

well today we have checked the pump by bridging 3+5 terminal on the relay and its fine, relay is ok as Ive swapped it with another 16v.
the light on the right of the dash is surely significant ^^^ -that kinda design like a heart monitor, which is the ECU isnt it, could it be the ECU? |

yes ECU. Make sure the diagnostic socket in the glovebox has the lid puched on properly as this has a jumper which allows the light to function.
is it sparking?
what immobilisers do you have? |

jumper, woolen item of clothing to keep you warm/metal contact inside a diagnostic socket lid that allows the light to function! lol
replace the ECU and say theres a wiring problem and you blow that one, what use is that?
So we can assume its not firing for sure then? |

all of them, especially the main body to engine strap, if they fail/go high resistance then the ECU is the next best earth path adnt hey don;t like it! |

could it be the crank sensor because there's nothing coming from the ECU to the fuel pump relay? |
