Antwoord op "02 Nissan altima won't start"Hello all, I also had a crank no start problem 06 qr25de. Replaced coils, plugs, injectors, fuel pump, head gasket/other gaskets. and checked all sensors with oscilloscope. Car still didnt want to start. We said f**k it and called wrench.com and won the lottery. A 35+ year nissan mechanic came out and figured out the problem. The coil packs are wired in behind the intake plenum and tend to wear out causing 2 of the coil packs to have a higher resistance which tricks the computer into thinking the cars being stolen and activates anti-theft mode. If anyone is having a no start problem have someone qualified check your coil packs to make sure they are the same resistance. The guy said hes seen this issue no more than 3 times in his entire career so its pretty rare but I also do see a lot of crank no start posts with no solutions being posted.
