I sold my beloved 1998 infiniti i30T 2 days ago that I’ve had for almost 20 years!!! The same day I bought a 2002 i35 with 158k miles but it won’t start. I turn the key it’s almost like it doesn’t have compression but I got it started for like 10 seconds and it died. Im worried it’s the timing chain but I thought Infiniti’s timing chains were rock solid? I don’t hear any chain slap or anything like that. The car is overall in great condition. The guy I bought it from said about 6 months ago he drove it home no issues and went to get in it and it wouldn’t start. He gave me the brand new alternator to go with it I only paid $800 for this car. It has no check engine codes. The oil looks good.The transmission fluid looks good and the coolant looks good. The key and the fob are kinda busted up as well. Maybe a security issue? I need your help guys

 

It doesn’t want to start with a jump. You have to really keep holding it. Im leaning towards a weak starter?

 

I have a 2003 I35 with 185,000 miles. I bought it from a family in 2006. The car only had 15,000 miles on it because it was driven by a grandmother. My dream find.

After so many years of faithful service, I have learned that a common cause for no starts is a faulty Crankshaft sensor and or Camshaft sensor. I would look there first. Just buy cheap ones off Amazon because they are easy to replace. If you can change a light bulb, you can change these sensors.

Do a search on YouTube for sensors on a Nissan Maxima. Maximas and I35 share the same engine parts but there are way more maximas sold. Therefore, more information on line. Good luck!

Pay attention to the red security light when you are starting the car, if the light remains on while cranking the NATS system might be malfunctioning and preventing the car from starting.

 

i agree with this assessment, if you don't know the history of this car , the CPS sesnors (3 total) are worth replacing for a number of reasons, and possibly could be the culprit.... and yes they do not always throw codes, Mine did not throw one code and dealt with them for over a year (used crappy aftermarket and problem came back, used OEM / hitachi, and all problems went away) and no codes during the entire process.

i will add, it would eventually start, though and then got really bad at the end and i got one nice start to drive straight to the mechanic to replace with OEM
