    there is no tension adjustment, it is automatic, either the tensioner is defective and has lost its spring tension or the belt is burnt, check both/

There is a tensioner. When facing the car, its on the lower right pulley. There is a bolts that faces down towards the ground. Tighten the bolt the belt tightes and vice versa. The car has two belts, the left side has the same thing. nissan got smart and put a single belt on the 06 and up.

Check the tensioner mount to make sure the bolts are tight.If that doesnt help ya then go to alternator and check the backside or underneath the belts to make sure there is no frays, cracks, wear tear. If all of these plus what the above person stated on Dec22 to ya. Go to your neighborhood auto parts, napa, or autozone and buy belt dressing to spray on the belts. remember to shut off the 350z before applying this unless you really want to loose your eyesight. Then, restart your car and let the belts do the work for you. eventually after a few revolutions(turns) you will hear a more quieter sound. Remember this is only a temporary fix if your low on cash!!

In the am my engine will crank but wont start until i pump the gas peddel 20 times then it starts, and will start everytime all day next morning wont star In the am its like it isnt getting gas??


Pumping the gas pedal on a fuel injected car doesn't really do anything.
However, cranking the engine for an extended period of time could "pump up" the fuel pressure.
You should have about 35psi in the fuel line when you first crank the engine. If the pressure is low, it could take 30-60 seconds to build up that pressure to get the engine to start. Min pressure is around 35-40psi. The pump in the tank could be leaking pressure back into the tank overnight, or the pump relay could be faulty.

Why does my car makes squilling noise when i crank up the car but stops


If the noise happens when the engine is first started, the serpentine belt may be slipping when the alternator is pulling hard.

I have a 2001 IS 300 with 160,000 mi. I was having trouble starting the car in the morning where it would take 2 or 3 tries to get it to turn over. It is in a garage in California, so not in extreme cold....


try if this works\improves your situation;

turn the key to ON but don't crank, let it sit for 2 seconds. Do this 2-3 times, then put it in the ON position, wait 2 seconds then crank. As for what it is, could be spark plugs, fuel pump\line issue, etc..

I have a 2001 saturn sc1 that is having intermittent starting problems. At times after its been driven ill go out to leave again and it won't start. No clicking when I try and start it either. Wait for...


I am having the same problem. did you figure out what was wrong with yours. I have tested all of the wires in the harness under the dash, they r fine. I pulled off the starter and had it tested; O'rilies said it was fine. It is a 5 speed, and I can push start the car just fine any time. Like yours, some days my car starts, some days it doesn't. The days it starts, it runs fine with no problems starting or running. the problem is the days that it wont start.

1999 Chevy S10 cranks but wont start


A very common problem on the 99 S10 is a leaky fuel pressure regulator in the intake plenum.What happens is when the truck sits for a few hours or more the regulator leaks all of the fuel in the fuel injection system into the intake air plenum. This does 2 things, 1 it has no fuel pressure when starting and 2 it floods the air intake with raw fuel. Sometimes if you turn the key on wait 3 seconds then turn key off then turn key back on and just turn key to crank starter for a split second and wait 3 seconds.do this 3 times to repressurize fuel system then crank to start(you will hear fuel pump buzz each time you do this.also you may have leaky fuel injectors. Try to crank engine with the gas pedel to the floor. This will tell the computer to stop spraying fuel trhough the injectors and it will start. Joe ASE Master Tech
