On Friday afternoon i washed my car and that night i got ready to go out and it wouldn't start. The light "Floor Temperature" lights up and it makes a buzzing kinda sound help please?

Did you wash the engine bay when you washed your car? What exactly does it do when you try to start it? Does it turn over, or just not make any noise at all?

If you washed the engine, then more than likely you got water in the Throttle Position Sensor connection. It would be a good exercise to remove the plug, and blow it out with compressed air. Clean the connections and follow up with some dielectric grease before plugging the harness back in. My .02 !!

Pomorza-i didnt washed the engine but the water may have gone through the vents...it doesnt turn over it jus wont statr and makes a funny noise

Zcurves- where is the Throttle Position Sensor? sorry I love my z to death its just im barely learning about it...

Zcurves i found it thanks i did what you said and it worked thank you so much!

hey guys today i tried firing it up and it wouldnt start again...i got the same buzzing sound i thought it would best to continue here than to start up another post....i repeated the same thing you said to do and clean the TPS but it still wouldnt work...any suggestions? thank you in advance!

It's got to be a loose conection somewhere.

I browsed the FSM (slow Saturday night :disappoin) and it looks like the Floor Temperature Sensor relay is powered up when you hit Start. The light is supposed to go on at Start and go off when On, unless the floor is hot.

It's in the Emission section.

It's possible that you just have a low battery or bad battery connections. The relay buzzes because you don't have enough juice to activate it completely, therefore not enough juice to Start the engine. Like Ford starter relays. Buzzz, buzzz, buzzz, crap, battery's low...

Hope I didn't kill your thread Datsunlover. Any luck?

hey ZedHead i had more of my friends look at it and they said it was the starter...we hit the starter with a hard piece of metal and it started? so they said to get my starter rebuilt and it should be that thanks for your input though when i get my starter rebuilt and if the problem continues i will take your advice into consideration

sorry it was a slow saturday night you should have

I had a Suburban with a starter that would refuse to stop unless I hit it with a stick.. fond memories.

When you have the starter out, it's a good idea to clean the ends of the heavy cables. You can even try putting some grease on them to keep moisture from corroding them. Thinking back to the old Sub, I swapped the start twice because it wouldn't turn over... looked at the cable after a weekend long endeavor and found that the corrosion was resulting in only a couple of the wires carrying current.
