This problem randomly came up 3 days ago. The car cranks for about 2 seconds before starting, and the VDC OFF and SLIP lights won't turn off. Once it's started though, it runs fine.

Two different places said it might be the crank or tb sensor that's making the car take so long to start, and that they don't think it's the starter or battery. The VDC and SLIP lights were sort of mysteries.

I don't want to take it to the dealership unless I have to, since it's so expensive. Any input is appreciated

 

VDC and SLIP lights on usually indicate a problem with your alignment or wheels. Have you done any work recently: new tires, drop, new wheels etc.?

 

not recently. haven't gotten an alignment in about 7 months, but that was when i changed the wheels last, so nothing new really

 

Do you have a check engine light as well?

 

VCD and slip light on, plus hard trouble starting usually indicates one of the crankshaft position sensors is going. Get a diagnostic run to see which one it is. Pretty common issue on our G's. I had one replaced at a nissan dealership 2 months ago for about $350. Same symptoms as yours, except my CEL was also on, plus I would get sporadic, infrequent hesitation when driving.

 

no CEL, but the crank sensor was a possible explanation that Autozone and another shop gave me. that's prob it. for those who had the wheel speed sensor repaired, how much was it?

 

just to let you guys know, i've contributed my ranting to another forum post out there. Long story short, I have the VDC, Slip & Check Engine Light all on ('04 G35 Sedan). The dealer replaced the camshaft sensor (bank 2) and that didn't fix a thing. [The code was P0345]. The dealer said that my timing was advanced and stuck in a forward position and that the only way to fix it would be to get behind my engine to R&R that part....dealer cost ($2,800 - $3,200). I then went to PrecisionZ in the Valley and they did an engine flush for me and thought that might alleviate the issue....needless to say, back to square one. My vehicle stalls as it idles low, and it hesitates accelerating beyond 65mph. I really would be indebted to anyone with a FINITE answer for this problem....

 

get behind your engine?????

I dont understand, please clarify.

 

a crank or camshaft sensor would throw a CEL.

I bet money it's the crank position sensor which seats on the side of your tranny. The sensor is pretty much a magnet that receives a signal every time your flywheel does a full rotation (which contributes to the motors timing). This is a very common problem in the 350z world, so much that Nissan put out a TBS for MY 03-04. It is a very easy sensor to change and the sensor its self will run you between $80-100. I suggest you visit my350z.com and search crank position sensor.

Good luck

 

mine did this it was cam position sensor. i replaced bank 2 but bank 1 was the problem. so i replaced them both cost me about 2 hours and 250 bux i had an service engine light as well tho. autozone will give you the tool to read the codes and reset them then you look it up and fix it.

 

i had this problem with my 07 g35 coupe check you brake fluid mine was low and the lights would come on once i topped it of no more lights

 

well this is my trouble now.i was driving at about 70mph and the car suddenly started baffleing then shut down.now it wont start.my mechanic change the crank sensor but still the same wont start

 

Check Engine Light code?


If it's gotten this bad, I would really consider stop guessing and let an Infiniti dealership take a look at the problem.
