I've had my F V8R about 6 weeks now.
Soon after I got it, it didn't turn over every time I tried to start it. Just seemed to switch on ignition and do some checks. Then it started on a second attempt.
Until last weekend. Tried to start it, it did its usual thing, but then I got a message saying battery low start engine. So I tried again and after a few attempts it started.
I got a new battery as I had noticed that my CTEK never got it to full charge.
Still had the problem, and it started getting worse so that it started maybe 1 attempt in 10.
Been through all the earths and other big connections from the back through to the front and on to starter motor.
Used a jump lead to bridge engine to body earth. No luck.
Plugged in my Foxwell diagnostic and it Diagnosed starter relay fault. Got a new one from the Jag dealer, who told me the relay was on the box to left of engine bay. Found the only 40A 5 pin relay in there and replaced it. Still didn't sort the problem, which was getting worse. Starting 1 in 20 attempts maybe, now it doesn't start at all.
I did notice on 1 attempt that it started just as I was giving up and taking my foot off the brake pedal. I thought there might be a problem with the brake light switch and jiggling the wires I did get a brake light switch fault on the dash briefly. Tried the brake light switch from my Disco 4, didn't help.
Has anyone come across this problem?
I know I need to run the diagnostic again, but I'm on holiday - which was supposed to be with the F Type.
Also planning to order a brake light switch in case it is different to the Disco one. FoMoCo part, seemed to be the same.
Any other suggestions?
Does anyone have a map of the fuses and relays for a 2015 V8 R?
Thanks for reading!
