[Fault codes 26, 46, 49]

Thanks for the tip, I'll have a crack at it tomorrow

[Fault codes 26, 46, 49]

I cleared the fault codes today. The engine still won't start. I haven't seen any more fault codes, so I assume it was just from when I disconnected the loom plugs.

I don't understand why it won't start, haven't had this problem before I unplugged the loom plugs??

Okay, thanks for the guidance!

Hi,

I have the G4 Link ECU with map sensor and no maf in my '92 model Nissan Sunny GTi-R.

The other day I had to change some vacuum hoses, and to get to them I disconnected the loom plugs. I put everything back together, and the engine would not start.

I checked that the plugs were properly plugged in, and that the vacuum hose to the map sensor was connected. All appearing to be fine.

Then I connected the ecu to PCLink, and got these fault codes:
26
46
49

 What do these mean?

What can I do about it?

Best regards,
Ole from Norway
