Tvrtastic911 Posted March 3 Share Posted March 3 Went to take my new k-series supersport out for its first blat in the sun today and it won’t start. 😭 Only had it a couple of weeks and it’s started/ran fine in the garage. But today it turns over, fires and dies. Seems flooded maybe as it will not restart (fire) unless left for a few mins. I have plenty of fuel. Bit in the dark with k-series as being a VW guy for last 30 years! any quick pointers? Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted March 3 Member Share Posted March 3 (edited) Good morning That's an unusual variation. How long does it run for after firing? Does it die suddenly or gradually? Try removing the fuel filler cap and seeing if that makes a difference. Jonathan PS: Do you have a multimeter?

Tvrtastic911 Posted March 3 Author Share Posted March 3 Jonathan. It runs for 2-3 seconds. If I pump throttle it dies and does not catch. I got it on charge now. Battery by no means flat, but needs a boost. It’s a new battery and starter btw (previous owner) Link to comment Share on other sites More sharing options...
simon_h Posted March 3 Share Posted March 3 Just to rule out something. You say it’s a supersport so I doubt it is but it’s not an eu3 car is it? In other words has it got a distributor or plug top coils? Link to comment Share on other sites More sharing options...
Tvrtastic911 Posted March 3 Author Share Posted March 3 (edited) No Dizzy (I’m familiar with that age tech 🤪) I have a multimeter but no clue how to use. Only bought it to test kids toy’s batteries. Edited March 3 by Tvrtastic911 Spelling Link to comment Share on other sites More sharing options...

Roadsport06 Posted March 3 Share Posted March 3 Has the immobilizer disabled? If not you'll get fuel on first start to run for a few seconds before there is no fuel 1 Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted March 3 Member Share Posted March 3 Your current (!) problem sounds more like fuel than electrics, but many Sevens run into starting problems and I recommend routinely checking battery oomph in the same way as checking fluid levels: * Turn the multimeter on and set the range to 20 V DC or similar * Put one probe on each battery terminal * Measure the voltage across the battery at rest * And the minimum voltage as it cranks (so that the starter is acting as a big load) * And then at 3,000 rpm (which checks the alternator and charging system). And report those back here for interpretation. : - ) Jonathan 1 Link to comment Share on other sites More sharing options...

I’ll try it again with spare fob now Link to comment Share on other sites More sharing options...

I’ll try it again with spare fob now In general you need to check the immobiliser, the fuel cut-off inertia switch, and whether you can hear the fuel pump joining in. ... Do you already have the wiring diagrams and layouts of fuses and relays? If you need these please send me a Private Message with your email address.

Orange Posted March 3 Share Posted March 3 I have a k series also, it sounds like the idle air control valve is not working correctly, usually coincides with a battery that is not fully charged. You could try resetting this. (Ignition on, press throttle 5 times (fully open each time) ignition off) Then try and restart. I am going into the garage in a few mins - happy to speak on the phone if you PM me your tel no if helpful. Link to comment Share on other sites More sharing options...

Wear hearing aids so hard for me to tell / locate sound of fuel pump. But there is a solenoid type sound when i switch on ignition that is not there when i remove the fuel pump fuse. i fear this may have been caused by me as in the week i reatched disconnected wire going to the live of battery, in order to make the 12v cig sockets that were not working from previous owner. Did not know why this was not attached. I presumed was missed when battery replaced. Link to comment Share on other sites More sharing options...

Orange Posted March 3 Share Posted March 3 Offer of a call still there - mine does something very similar sometimes, usually caused by a low battery but I can always get it going. Link to comment Share on other sites More sharing options...

Did not know why this was not attached. I presumed was missed when battery replaced. Very interesting. I suggest doing those three battery voltage tests. And inspecting and wiggling all of the relevant wiring and connections, including the battery and engine earths. And if you have a battery that can be topped up checking the fluid level in the cells. Jonathan PS: If you have a non-factory accessory / cigar lighter socket check that it is appropriately fused. Link to comment Share on other sites More sharing options...

Ok. Im going to hope to hell that this is the case. im going to leave it for a few hours charging as I’ve certainly turned it over about 30 tomes now and its only worse. when i ‘fixed’ the cig lighter it was monday and ive not had it in charge since then. Perhaps its drained…. never had a car that drains in a week though, especially after turning over so strongly 😒 is there a way of checking the fuel cut off switch, other that jist pressing it to reset?

Orange Posted March 3 Share Posted March 3 Have you reset the immobiliser after you disconnected the battery? By setting it (rapid flashing) and then unsettling it? It sometimes takes several presses of the setting button. Link to comment Share on other sites More sharing options...
OldAndrewE Posted March 3 Share Posted March 3 Just a thought, perhaps there is a reason the cig lighter was not connected, i.e. something wrong with the installation that causes problems Link to comment Share on other sites More sharing options...

By setting it (rapid flashing) and then unsettling it? It sometimes takes several presses of the setting button. Tbh didn’t really disconnect the battery. Once I identified the disconnected wire I just reattached it to live terminal. But I probably disconnected it when checking all the fuses to see if 12v was wired into them. On/offed the immobiliser several times now and it seems to be setting correctly. I've got a family lunch booked now, so I’ll be moping into a pint for a few hours, pondering all your replies. Thanks for the support all. Really appreciate. Link to comment Share on other sites More sharing options...

But I’ve already taken the 12c socket off the battery again with no joy. Link to comment Share on other sites More sharing options...
jody391 Posted March 3 Share Posted March 3 Have you tried pressing the inertia switch? Mine triggered when dropping it down from the jack quite fast once. Link to comment Share on other sites More sharing options...

Inertia switch? This the fuel cutoff? Yes i pressed this diaphragm. Its not had a drop or jolt though. Link to comment Share on other sites More sharing options...
