03 350z with viper aftermarket alarm cranks just fine but sometimes i have to try a couple of times for it to start. I did some research and I really dont know how to check if its "throwing a nats code". I only have one key and one alarm. I previously had a problem with the battery but when this happened no lights would turn on just the battery light so i cleaned the battery and tightened the loose cable. Could it still be the battery? Today it happened to me after i turned off the car which was hot at a gas station it took me like 8 tries for the car to turn on I popped the hood to mess with the battery cable and it did but could it be my fuel pump?

Sorry for the long text just clueless here
Thanks in advance.

 

Check what codes your throwing. but this sounds like a cam sensor failing. it happens on the regular. hard starts ,stalls , and sluggish.. check it out easy fix big change...

could be wrong but this just happens to me and i took it to Nissan but they wanted to charge out the *** so i just bought the part for 50$ and installed it myself.
