What's up guys , I'm new to the site, to start my name is George and I own a 2006 350z which I manual swapped last year.

2 month ago I changed the battery and the car decided to mess with me. It cranks over strong and after about 10 cranks it will start. But after driving it it take 5-10 minutes to want to start again.

I started with changing cam and crank sensors, then renewing all the grounding points under the hood. followed by checking for broken or corroded wiring. I check the NATS as well and still having the same issue.

My CEL is showing u1000 but I'm guessing that's cause the car used to be auto and is now missing the TCM.

My IPDM makes a clicking sound from the starter relay which I have also replaced it clicks on and off every 5 secs or so. I have ran into a dead end here as I have no idea what to do next. The car runs amazing once it starts but getting it to start sucks and is embarrassing when out in public lol.

If you guys could help I would seriously appreciate it. I have asked 3 groups on Facebook and no one knows what to do almost like no one works on there own cars anymore.

Any questions you guys have ill be logging in every 1-2 hours. I really want to start driving my Z again so please ANYTHING you can think if will help.
UPDATE-----
Car wont start takes 12-15 cranks to actually start
At this point i have:
Change crank sensor twice
cam sensors twice
check all my ground
changed O2 sensor (sensor 2 bank 2)
resealed the intake manifold
replaced fuel damper/regulators
checked for spark and fuel
MAF sensor is confirmed working
the Z has actually gotten harder to start.....

IDK anyone in the Fort Myers Fl area that might be a guru, honestly I'm willing to pay someone to come here and tell me what has to be fixed.

Did you use oem sensors? Aftermarket tend to have issues

Kanedaz350

Yeah, I used OEM sensors, got some help today, and we are pretty sure its a fuel pump (weak) issue. Car needs starting fluid to start and then dies from no or not enough fuel. I'll post tomorrow after the pump install and let you guys know.

Having the same problem, any luck?

Kanedaz350

no, no luck yet. its going to nissan to get diagnosed next week.

Kanedaz350

Ok so today I made the appointment with Nissan for next week to have it diag. So far i did change plugs and a friend hooked me up with a DW 255 fuel pump fo freeeeee lol car still remains the same hard to start but it does start and once its hot its even harder. while i wait for the appointment with Nissan next week I'm going to get a ohm/voltage meter and i am going to test all the sensors i have changed.



Was told that my issue does sound fuel related, possibly either the main damper from the fuel line to the rail or...... its getting vapor locked because of clogged fuel vent lines... all that is Chinese to me so if anyone can explain what to look at i would really appreciate it.
