Ole Håkon Tokvam Posted February 12, 2013 Report Share Posted February 12, 2013 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:264649  What do these mean? What can I do about it? Best regards,Ole from Norway Quote Link to comment Share on other sites More sharing options...
Levon Luther Posted February 13, 2013 Report Share Posted February 13, 2013 Â I dont know what they would be for your motor / computer, but I do know how to find out To read them, turn the key to 'ON' Look at the top bar where it tells you your error codes in Red text. Click the text The event log should describe what the code is; For example, I had just soldered two wires together for my iat sensor. I wanted to make sure that the sensor read correctly before I hid the wires. At the turn of the key, I got AN5 Voltage low. I was pissed. Turns out that the wires were touching, so it was going to ground. Once you figure out what is wrong, fix it and clear the codes to see if it is fixed.

Levon Luther Posted February 14, 2013 Report Share Posted February 14, 2013 Also - before you disable them, try just widening the range. Perhaps they are throwing fits because of that.... Example: I have a 0-100psi AEM gauge. On start up I see 105+ PSI. I was getting an error because it was outside the limits, so I just bumped the limits, and it actually reads like 104ish PSI even though the gauge wont read that high. Link FTW.

Ole HÃ¥kon Tokvam Posted February 14, 2013 Author Report Share Posted February 14, 2013 Okay, thanks for the guidance! Quote Link to comment Share on other sites More sharing options...
Ole HÃ¥kon Tokvam Posted February 23, 2013 Author Report Share Posted February 23, 2013 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?? Quote Link to comment Share on other sites More sharing options...
Simon Posted February 24, 2013 Report Share Posted February 24, 2013 Will need to start with the basics. Check for fuel and ignition at the correct time. You can do ignition and injection test through the software. Quote Link to comment Share on other sites More sharing options...
Ole HÃ¥kon Tokvam Posted February 25, 2013 Author Report Share Posted February 25, 2013 Thanks for the tip, I'll have a crack at it tomorrow Quote Link to comment Share on other sites More sharing options...
Simon Posted February 27, 2013 Report Share Posted February 27, 2013 As your applications is a distributor based engine you will only have one ignition drive and one coil, so depending on where the rotor in the dissy is pointing will depend on which cylinder you get spark. Â Given you get spark this indicates the coil and ignition drive are good. You will need to check the timing when cranking to make sure its firing at the right time.

Simon Posted February 27, 2013 Report Share Posted February 27, 2013 It will be a two person job with a timing light. Light on #1 lead and check when cranking if there is spark and if it is at the right time. If there is then move on to fuel. Quote Link to comment Share on other sites More sharing options...
