Hi guys, need some help! Car's been sat for a month whilst i've been working on it, went to start it today and it won't fire up. It turns over and the fuel pump primes, from what i've read on here it sounds like it could be the crank sensor? or could it be the ecu? Also, where is the crank sensor located?Thanks. |

crank sensor is bolted to top of the gearbox right where it meets the engine, black plug with a 10mm bolt holding it on. google images > "gti6 crank sensor"have you physically checked for spark and fuel at the rail? ________________________________________ 306 rallye reproduction decals (full sets/individual decals) | 306 b-pillar textured vinyl weatherstrips306 slam panel esso stickers | 306 yellow / orange / pension fund red side door badges gti6 inlet manifold badges | 306 rear boot badges (p2/p3) winner of Extraction of toys from prams with outstanding vigour award 2009 [source: gti6 owners club] |

Haven't checked that yet, i found this... ... behind the battery box. Could this be the culprit? |

That's the fuel relay from behind the battery box ? What work have you been doing the car ? |

I changed the passenger side wheel bearing, p/s cv boot, replaced front brake lines, calipers, flexi hoses. I had the battery box detached so i could unplug the abs sensor, must have hit the relay whilst the box was detached!  |

If the pump is priming then it's working but worth changing I guess ? It's got fuel in the car I assume ? |

I'm pretty sure the pump is priming, though i remember hearing a clicking sound before... might be imagination though.  |

Try the fuel cut-off switch. It's a big red button by the top suspension mount on the battery box side.Make sure you haven't bumped it and it needs resetting. If it does, just press it to reset it.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone  |

Looking at the crack in the double function relay I would say if the red button is ok that will be your culprit.Carl ________________________________________ C.G.Cars of Leicester, Peugeot/Citroen/Renault specialist Tel: 01162 624498/07799 405184 WWW.CGCARSLEICESTER.CO.UK36 narborough road south, Leicester LE3 2fn MOT station now open, tests £35 with a free retest.

I tried the cut off switch which didn't resolve the issue, if it is the relay would the engine management light not light up on the second ignition turn? |

The relay does two functions, it supplies the fuel circuit and also the ignition circuit, I change a lot of these when they have been damaged like your have the contacts inside corrode, open it up and hold the contacts together, that will give you a definite answer.

pull the casing off it and check it for water damage but that's a common issue as well________________________________________ 306 rallye reproduction decals (full sets/individual decals) | 306 b-pillar textured vinyl weatherstrips306 slam panel esso stickers | 306 yellow / orange / pension fund red side door badges gti6 inlet manifold badges | 306 rear boot badges (p2/p3) winner of Extraction of toys from prams with outstanding vigour award 2009 [source: gti6 owners club] |
