Hi everyone,

I'm experiencing some issues with my 2005 G35 Coupe (A/T) 115,000 miles. I've already searched and dug through the forums for as many possible causes to my issue and have begun trouble shooting, I'm writing this post in hopes that I don't miss a simple symptom or cause.

My car does not start easily, I turn the ignition and it takes several seconds, sometimes ten for it to finally turn over and spring to life.

Things I've already done:
-Fuel pump is fairly new, only been in the car for ~7,000 miles, secondary fuel level sensor replaced at the same time.
-Brand new battery just swapped in, had it checked to make sure it's not defective
-New Spark plugs put in at 100,000 miles
-Removed the MAF and cleaned it properly using MAF cleaner

Things I have yet to check/try:
-Fuel Pump Relay
-Crank Position Sensor
-Camshaft Sensors
-Clean the Throttle Body

Is there any other likely culprit that I may be missing?

-No error codes, not even pending
-Idle RPMS are perfectly normal and within spec
-Engine temp sits right at the halfway mark once warmed up and never fluctuates

Other issues I've been experiencing include a radiator which is clearly at the end of its life, already ordered a replacement and will have that installed as soon as it arrives; and an ongoing issue with my fuel gauge not always being accurate (was worse before I replaced the fuel pump).

Thanks for any help!

 

Starter or starter relay?

 

Bingo

 

I got mine fixed by shipping the cluster to rapid electronics on ebay. I think they soldered the circuit board.

 

Same issue with the car I bought. Starter solenoid craps out and then it won’t engage. Eventually it will skip and sound like crap.
