Restoring 2003 M45- help needed

Postby ryoung » Thu Dec 17, 2020 10:36 pm

So I just brought a 2003 M45 that was sitting for about 2 1/2 years from a friend of mine. I having 3 issues

1. It had a bad power steering pump. I changed the pump and found it had a leak in a return line. Replaced the line and then I found it was still leaking. Found out that it was coming out the resovir after the car was turned off. I replaced the resovoir and now a new leak. still searching for the new leak

2. ABS, slip and VDC lights have always been on. I replaced brakes and rotors all the way around and the front drivers hub and wheel bearing. Still getting the light. I hooked it to my reader which pulls ABS lights but it won't read it. I read somewhere that this year ABS module won't read on a code reader. Is that true? any ideas?

3. It doesn't start right up. Not a starter issue though. It literally does nothing and I have to turn the wheel and play with it for a bit to get it started. This happens about 60% of the time.

Thanks for any help

Sounds to me like it has some significant electrical gremlins, possibly accident-related.

Test battery voltage both off and running. Remove and clean ALL grounding points (can also cause the issues you're seeing).

PS reservoir overflowing is an odd one... wondering if the feed line has a blockage or restriction.

I second the cleaning of grounds. You'd be surprised how much stuff relies on a nice clean ground. I do it every 2-3 years as regular maintenance.

I'm experiencing the exact symptoms on my y34 2003 m45 except my ps is fine. Have you figured out the abs/tcs issue and the intermittent starting issue?

Yes, and the ABS will have its own, dedicated ground lug, usually someplace on the frame right near the ABS. Wisely, Nissan keeps that critical ground path fat and short, but it is exposed to the road and rust never sleeps.
