V70R Will not start

Hi ,

This is a strange one, I recently decided to put a new battery on my Saffron V70R. Drove into town then back home with my new purchase. Removed old battery and put new on. Put radio codes in . Tried to start car and the engine spins but will not fire at all.

Have pulled all fuses and checked.

Have tried starting with immobiliser fuse out.

Have locked/unlocked with transponder numerous times.

Have checked fuel pressure on rail

Have checked there is a spark

Will not start!

 

Any ideas?

 

Thanks

Try jumping / closing the main relay. 

The safest way to do it (in my opinion at least), because the current going through it is huge, is to remove it's plastic cover & manually shut the relay. Making a jumper is difficult as the spade connectors you would need would have to be about 15mm. 

If that works, the diode in it has likely fried. As a stop gap measure, until you can get a new relay, the diode can be removed and the relay will work. 

 



I should add that if you need to shut the relay, you can wedge a pin in there to keep it shut, for long enough to drive to get the parts / to test whether it works.
