hello everyone sorry if i post this on a wrong place but i dont know where to post it. Ok my problem is that my 06 g35 6mt wont start it cranks but wont start i tried jump start it and then it started but then it wont turn off even with the key out please HELP!!!!!!!!

 

most likely crankshaft position sensor. I would try to use a OBD-II reader to see if there are any codes.

 

Thaks for your advice but I got it fixed it was something in the ipdm I gave a little hit on the relays and it started fine and now I can turn it off fine

 

I have a similar problem. How did you figure out it was the IPDM?

 

First I thought it was the battery but I saw in a lot of posts with the same problem as mine and almost all said it was the ipdm and also when I connected the battery I heard like a clicking noise coming from the back of the battery (where the ipdm is located) I just shake it and hit it a few times and it worked
