morgymoo · 3rd February 2020, 19:15

Hi all.This is my first post so hi to you all.Hope my explanation is clear?. So my son has a Rover 75 1800 petrol on a 2003 plate. Wednesday morning it wouldnt start, so advise by a friend he put new starter and battery on,still no start. He told me about this on saturday afternoon, i then went and had a look. Here is what i found ignition on all dash lights as should be,batery voltage checked at 12.60 v, turn key to start and nothing no cranking. Ithen checked voltage to starter there was none. I then put + wire direct to starter,started up immediately ran for bout 2 seconds cut out. I did this few mor times and same thing run 2 seconds cuts out.still no start from key.Any ideas anybody ?
Thanks in advance

Could be fuel filter separation, common issue. Lift out the rear seat, under the passenger side is a cover for the fuel tank and filter. Remove the cover and check if the filter has separated slightly. Twist back together and try again. I'm on my phone so can't link to all the threads. I'm sure someone will be along 😎

Sounds like a damaged EWS 3 immobiliser to me, does the car have a sunroof?

No, there is no sunroof.what action would i need to take to verify this ?

Check for water ingress in drivers footwell, have you got two keys? if so have you tried them both?

Ok then, perhaps the transponder in the key has a data fault, if you have a spare key, see if that works

To begin with, which wire are you talking about, the large diameter red cable directly from the battery positive terminal or the white/red wire to the starter solenoid?

Hi Simon the wire to the solinoid white red has no power. Big red wire has battery voltage

No voltage with ignition on?

Thanks Graham. The immobiliser is inhibiting starter motor operation. It will also prevent fuelling which explains why, when you by-passed the immobiliser, the engine ran for only 2 seconds.

The next stage is to determine the reason.
