Guest Worried Posted April 4, 2020 Share Posted April 4, 2020 So I was driving normally and suddenly my MB6 (b18c4) just died. It cranks but it won't start. Checked the fuses and main relay. Fuses were just fine but main relay isn't clicking. I replaced the main relay but still it isn't clicking. Any ideas? Quote Link to comment Share on other sites More sharing options...
0 dr_broon Posted April 4, 2020 Share Posted April 4, 2020 Could it be the distributor? Sounds a bit like what mine did when it died. 1 Quote Link to comment Share on other sites More sharing options...
0 Guest MB6 Problem Posted April 5, 2020 Share Posted April 5, 2020 Fault code 0 so ECU is not getting power. Could it still be distributor? Quote Link to comment Share on other sites More sharing options...
0 KiNK43 Posted April 5, 2020 Share Posted April 5, 2020 Have you checked fuses? Engine bay aswell? 1 Quote Link to comment Share on other sites More sharing options...
0 Gel Posted April 6, 2020 Share Posted April 6, 2020 No 12v feed to the main relay means you should be suspecting a faulty ignition switch . 1 Quote Link to comment Share on other sites More sharing options...
0 Dave Posted April 6, 2020 Share Posted April 6, 2020 As above, no feed to ECU deffo sounds like either fuses/possibly another relay or ignition switch. Quote Link to comment Share on other sites More sharing options...
0 Guest Send help... Posted May 6, 2020 Share Posted May 6, 2020 I have now checked all fuses, grounds, main relay, ecu and ignition switch. Everything is okay but it still doesn't start. It cranks but it won't start. Main relay isn't clicking and ecu gives 0 code. I am out of ideas. Quote Link to comment Share on other sites More sharing options...
0 Guest Send help... Posted May 6, 2020 Share Posted May 6, 2020 Also main relay is getting power from ignition switch and I have changed the main relay so this is a huge mystery. Quote Link to comment Share on other sites More sharing options...
