Hello everyone seeking advice, ive been building a 350z for some time now it, it cranks but wont turn on. Sometimes when I crank it itll turn on and idle and run just fine but once I take the key out itll just crank and crank no start, ive changed my MAF sensor,Cam and crank sensor, checked all my relays and fuses, Ive read that it could be my immobilizer but I dont think so as it turns on occasionally, any advice would be nice thanks.
