gtiles85 0 Posted September 25, 2008 Hi, got everything complete today on the car went to start it up and the engine was just spinning over and not fireing. undid the feul hose and looked to see anything coming out and nothing. Havent checked to see if there is a spark there yet but i was just wondering if i needed a different fuel pump for the gti6 conversion or not, or if anyone else has had similar trouble ? Cheers, Les.

welshpug 1,657 Posted September 25, 2008 have you bypassed the inertia switch? Share this post Link to post Share on other sites
gtiles85 0 Posted September 25, 2008 have you bypassed the inertia switch? What / where is the inertia switch ? Share this post Link to post Share on other sites
Peetypug 5 Posted September 26, 2008 is your ecu unlocked? Does the fuel pump prime when you turn the ignition on? The inertia switch should have been near to the battery when it was in the 306, its black with a red rubber top, it cuts the fuel pump off in a crash. You will need to but the plug off and connect the wires together Share this post Link to post Share on other sites

You will need to but the plug off and connect the wires together Yes the ECU is unlocked, the engine was previously in a 309 gti before mine, i know the switch your talking about, though mines got a black rubber top, i will give that a go.

gtiles85 0 Posted September 26, 2008 Tried all of the above and still no fuel coming through, and it doesn't prime itself either, also dont know weather this is connected or not but the starter motor ativates on the 2nd turn of the key and not the 3rd like it should do, which means at the moment i can turn the ingnition on and walk away leaving the starter motor turning over that might be something different tho. Does anyone know if an unlocked ecu can lock itself if its been left disconnected for a while ? (2 weeks) Share this post Link to post Share on other sites
welshpug 1,657 Posted September 26, 2008 sounds like you have the switched live and starter motor wires the wrong way round. do you have constant live at the relay as well as switched? Share this post Link to post Share on other sites
gtiles85 0 Posted September 26, 2008 sounds like you have the switched live and starter motor wires the wrong way round. do you have constant live at the relay as well as switched? I was thinking that, i will have a check once i have found out what wire does what and where the relay is. Do you reckon that will solve my fuel problem aswell ?

Peetypug 5 Posted September 26, 2008 was it running when it was in the 309? have you cut and reconnected any of the wires? Share this post Link to post Share on other sites
taylorspug 7 Posted September 26, 2008 Yes the switched live to the relay will solve both fuel and spark problems, as both are livened up from there. The pump will prime once you have the switched connected. Share this post Link to post Share on other sites
gtiles85 0 Posted September 26, 2008 Where abouts is this relay for the switched live & starter motor as the only plugs i disconnected were these ones And the plug that does the ingnition i figured out its this one When the engine and loom were in the 309 it all worked perfectly so im assuming that its something that i have done. has anyone got a wiring diagram that could be emailed or does anyone know what pins (1to9) would be the 2 wires...... thats if they are in this plug ? Any help would be greatly appreciated as this is really starting to do my head in now !!! Share this post Link to post Share on other sites
welshpug 1,657 Posted September 26, 2008 those wires are laid out totally different!! you need to match up the wire numbers either side of those plugs and I reckon you'll be onto a winner. you can pull the terminals out of the plugs quite easily too Share this post Link to post Share on other sites
gtiles85 0 Posted September 26, 2008 Most of the numbers do match apart from 2 which are on the new loom ( the wires going down in the 2nd photo ). My only other guess is the wire layout is different in the 309 than the 205 and that loom was made up for the 309. Share this post Link to post Share on other sites
welshpug 1,657 Posted September 26, 2008 no most 205's and 309's are the same, what differs is the layout of the wires over the years that they were built. most of isnt good enough lol, they all need to match, if not in number at least function! Share this post Link to post Share on other sites
Peetypug 5 Posted September 26, 2008 (edited) comparing your 2 brown plugs to mine they are in the same order the others (on the bottom of pic 2) i cant be sure of till i look at my loom tomorrow but just so you know, these are what they are on mine only 3 wires are needed on the 6 pin plug 9 pin plug 1 - brown 52 = reverse light switch 2 - purple 53 = reverse light switch 3 - white 47 = coolant temp switch 4 - blue 47a = coolant temp gauge 5 - green 7a = alternator 6 - red 30 = oil pressure warning light 7 - white 30a = oil temp sender 8 - yellow 30b =oil pressure gauge 9 - red 2 = switched live 6 pin plug 1 - empty on mine 2 - cream 76 = fuel pump 3 - empty on mine 4 - blue 112 = tacho loom 5 - empty on mine 6 - blue 46 = starter hope they help you in some way Edited September 26, 2008 by sorrentopete Share this post Link to post Share on other sites
gtiles85 0 Posted September 26, 2008 Would the constant live feed come straight of the live battery terminal and go to the relay, because looking at some old photos of the engine when in the 309 there is a red wire going from the live terminal and then through the bulkhead by the strut ( see photo ) would that be going to a relay in the fuse box ?

welshpug 1,657 Posted September 26, 2008 no, constant live would be from the shunt box on the slam panel, that red live is likely to be for an Amp. Share this post Link to post Share on other sites
Peetypug 5 Posted September 27, 2008 the only other thing i can think of is, cut your plugs off your 8v loom then cut each wire one at a time and mate them up. That way you've got the right order from your looms Share this post Link to post Share on other sites
welshpug 1,657 Posted September 27, 2008 noooo!!! there's no need at all to cut them, you can unclip the plug and pull the spade terminals out easy! Share this post Link to post Share on other sites
Peetypug 5 Posted September 27, 2008 or you could do as welshpug says Share this post Link to post Share on other sites
gtiles85 0 Posted September 27, 2008 A BIG BIG Thankyou to you guys for your help, and sorrentopete for the list saying what wire does what as it now starts up fine, all i have to do is put the new calipers on and then take it out for a test drive !! So thanks once again, if theres a meet coming up then looks like im gonna owe a you guys a couple of drinks !!! Share this post Link to post Share on other sites
