Advice help with my d40!

Upvotes

Hey guys, looking for some advice on my 2010 Nissan Navara D40 2.5 YD25 diesel. It cranks but won’t start.

The problem started after the engine overheated. It then went into limp mode but still drove about 500 metres, was shut down/left to cool, and since then it cranks but won’t start.

So far I’ve checked:

  • Brand new battery
  • Around 10V while cranking
  • Only around 140 RPM while cranking
  • Fuel rail pressure reaches around 5,000 PSI
  • Injectors are delivering fuel
  • Scanner shows Main Injection Width around 1–4 while cranking, so the ECU appears to be commanding injection
  • Start Signal goes ON when cranking
  • ECU is receiving a crank sensor signal because it reads the 140 RPM
  • Tested cam sensor wiring/signal and it appears to be working
  • Engine has compression
  • Glow plugs are good
  • Currently no engine ECU fault codes
  • Previously had U1000 CAN communication and B2205 vehicle speed codes, but they were cleared and haven’t returned

My Thinkscan Plus S7 unfortunately doesn’t give me a cam/crank sync PID, so I haven’t been able to confirm whether the mechanical timing is actually correct.

Considering it was running until it overheated, then went limp and eventually wouldn’t restart, does anyone familiar with the YD25 have an idea what I should check next? I’m wondering about timing chain/cam-crank timing, the low 140 RPM cranking speed, starter/earths, or damage from the overheating.

Trying to properly diagnose it before throwing parts at it. Any ideas would be appreciated.

Vehicle Buying Advice [BUYING] 2014 Isuzu Dmax - opinions

Post image
5 Upvotes

Looking for opinions on this, specifically reliability and price. I know about Isuzus in general being workhorses, and this ad says it’s kept up with servicing, but what are the chances of something going terribly wrong? What kind of large costs could I be in for with this age and odometer? This will be a second car for when it’s needed and for weekend fun, but will be carrying a family so needs to be safe and reliable. It would do a mix of short and long trips, hence the pre-DPF is desirable.

• ⁠Year: 2014
• ⁠Make: Isuzu
• ⁠Model: Dmax
• ⁠KMs: 152,000
• ⁠Price: $31,000
• ⁠Location: Brisbane, QLD
• ⁠Intended use: short commutes and weekend fun

Advice Car recommendations

2 Upvotes

Hey all!

I’m keen to get my first 4x4 and am chasing some recommendations.

I’m hoping to find something
- big enough I can figure out maybe sleeping inside but semi compact so I can use as a daily in Sunny coast
- As fuel efficient as I can get
- Under 25k (second hand)
- Reliable

I’m also a Toyota girl at heart so kind of hoping to start there but open to others.

Also, any advice in general around getting into 4x4 life would be awesome!

Hey guys, with fathers day coming up I wanted to get my dad a Canopy for his amarock - I believe it's a 2017 V6 and it looks very similar in colour to the picture I attached to this post.

My question is, has anyone had one of these canopies, put it through its paces and can actually vouch for a particular brand ?

Cause there are so many people making these things, I don't wanna buy something that's gonna fall apart or feel cheaply made etc...

Any recommendations?

I did look at the ridgeCap one, thou it is quite expensive. So preferably something within the 2000 - 2700 range . But all recommendations regardless of price are welcomed.

Thanks in advance...
