johnpbransfield Posted October 31, 2019 Share Posted October 31, 2019 car running fine. Put it on trailer to bring it home, 30 minutes later it will not start. It has a strong spark and the fuel pump is working fine. Any ideas what to do next. I have not detached the fuel line yet in the engine to make sure fuel is coming through. How do I do this? Any advice much appreciated as always. Thanks in advance. Link to comment Share on other sites More sharing options...
SM25T Posted October 31, 2019 Share Posted October 31, 2019 Status of immobiliser LED ? Try pressing down hard on the top of the inertia switch. Link to comment Share on other sites More sharing options...
johnpbransfield Posted October 31, 2019 Author Share Posted October 31, 2019 SM25T, thanks, have pressed numerous times but not hard!! But fuel pump is whirring away. Will try pressing hard tomorrow.Warmed it up for 30 mins prior to putting it on the trailer.....30 mins later, it turns over fine but wont fire. I presume something has dislodged in transit.

SM25T Posted October 31, 2019 Share Posted October 31, 2019 If fuel pump is running, it won't be inertia switch or immobiliser. Good idea to check fuel from open hose (carefully !!!) Link to comment Share on other sites More sharing options...
SM25T Posted October 31, 2019 Share Posted October 31, 2019 Check all fuses ... especially the one for the ecu Link to comment Share on other sites More sharing options...
johnpbransfield Posted October 31, 2019 Author Share Posted October 31, 2019 Yes, was wondering about that, do you know which one it is or called on the fuse list? Thanks Link to comment Share on other sites More sharing options...

SM25T Posted October 31, 2019 Share Posted October 31, 2019 On my k-series it is the bottom one at 30A. Just check every fuse on the rail. Link to comment Share on other sites More sharing options...

garybee Posted November 1, 2019 Share Posted November 1, 2019 Blast of easystart down the intake. If it starts you've ruled out ECU/spark etc. and know you're looking at a fuelling issue. Link to comment Share on other sites More sharing options...
johnpbransfield Posted November 1, 2019 Author Share Posted November 1, 2019 No joy yet!Going to take the scuttle back off and see if any wires got trapped when putting it back on which may have rubbed whilst on the trailer.thanks for all the comments!

Member Jonathan Kay Posted November 1, 2019 Member Share Posted November 1, 2019 30 minutes later it will not start. It has a strong spark and the fuel pump is working fine.What happens when you turn the key... does it turn over, click or nothing?What's the battery voltage at rest, and when you try to start?Going to take the scuttle back off and see if any wires got trapped when putting it back on which may have rubbed whilst on the trailer.Yes, check all the relevant wires and connections, including earths....do you know which one it is or called on the fuse list?Most common layout on Sigma engined cars is probably:but there are others, including one undocumented. If that doesn't match please tell us what values or colours you have where and I'll try and work out which it is.Jonathan Link to comment Share on other sites More sharing options...
johnpbransfield Posted November 1, 2019 Author Share Posted November 1, 2019 It lives........and the winner is Gary B!Tried the easy start and it fired checked the injector bits and they were working. Unplugged the fuel lead to the engine..but no fuel coming through. Boot floor our and fuel pump out ( only 11 months old) and the pipe that goes to the outlet of the pump had come off....so easy fix with a cable tie. I am hoping it was not pushed home properly during manufacture! All back together and it fired up. So many thanks to you all for all your suggestions....I have learnt a lot today.After the club track day at Croft it has not being starting as well as it used to....I suppose it could be related if the pipe was getting looser and not sending enough fuel through for tick over.

John Vine Posted November 1, 2019 Share Posted November 1, 2019 Glad to hear you've fixed it....and the pipe that goes to the outlet of the pump had come off.Do you mean at the plastic union on top of the pump?or some internal connection within the pump itself?JV Link to comment Share on other sites More sharing options...
johnpbransfield Posted November 1, 2019 Author Share Posted November 1, 2019 hi John ....no it was inside the pump...so just pumping the fuel around instead of out! Link to comment Share on other sites More sharing options...
