Warmed engine won't start back up

[Neejay]

Whenever I drive my car and it warms up, if I shut it off, and immediately try to start it back up, it won't start. It seems like it's not getting the fuel. I have to press the gas pedal for it to start up, then it's fine.

This doesn't happen when the car is cold, only after it's operating temp/been driven around.

MAF!! I went through 3 different mafs. First one worked for quite sometime and then started to fail as your describing. The 2nd one after a few weeks of working would shut the motor off as i would come to a rolling stop at a red light. The 3rd would would start up idle but not allow me to use the accelerator at all.

hope this helps diagonose your situation. Check maf voltages or use your powerfc

Damn, mine is kinda doing like your 2nd one did too. The idle drops a little every now and then, but sets back correctly. And as for my original problem, sometimes it also starts up, but then the rev start to die, but then raises, then gets a little lower, then goes up to normal.

Let me know if you find out anything.

On Skylinesaustralia.com, someone has recommended I check the coolant temp sensor. Another source also stated to check/replace it.

coolant temp sensor is a comomn problem in nissans,but ive checked mine with a scanner and it was cool. Im going to check it again when it gets warmer out.
