Howdy from Carolina. I tried to start my Maxima 2 weeks ago it was completely dead. I switched out the battery and the fusible link. The lights came on in the car after I changed the fusible link. I had a tough time with the fusible link because it was welded on! I used the wire cutters to cut off the lug nut and about an inch of the positive battery cable. I went to the junkyard and cut off part of a battery cable from another Maxima. I spliced the junkyard battery cable and the original positive cable and voila I had lights inside the car.I tried to crank it nothing!So I changed the starter I tried to start it I heard one click and a loud buzzing sound. The car never cranked. I plugged in the OBD2 and I got a body throttle code. I was thinking it may be the ignition switch but I may just need new battery cables..a little help please I'm stressing out here!!!!

Today I turned the key to the on position for about ten minutes. The whirring sound happened as soon as I turned the key to ON. I turned the key back to off again after 10 minutes. Then I turned the car to start! Then I was able to start the car!!! However the idle sounds off and the check engine light is on again! I read the codes with my OBD2 scanner and I got
P0102
PO444
PO223
P2135

I can kiss those new boots from Aldo's goodbye.Sigh! I have to buy an EVAP canister and mass air flow sensor. Just changed the thermostat a few weeks ago and I just saw a leak under the car. I felt around the thermostat housing though and I didn't feel anything wet. I read that the o rings can wear out on the water pump and cause leaking. Hopefully this is the case.
I already ordered a new throttle body because the whole body costs less than the sensor. I ordered an ignition switch too I'm not sure if I need it yet though. I have to check Ebay's return policy on the switch. I'm going to hold onto it just in case.

Recap car started after doing a reset thing I read online. I have new codes to deal with and I am pissed about that! And I have to figure out what the heck that whirring noise is!

If you spliced the main battery cable you will likely have more trouble with starting as any splice needs to be soldered or it won't carry enough amp to start properly.

And, you lost all computer memory when the battery lost power to car, meaning the computer lost all settings and why the codes and crummy running. I'd drive the car to let the computer relearn some stuff as it may well put out some of the codes you don't need parts for as they are fake codes. NEVER buy parts indicated when you first run up a car after a dead battery.
