ok i have a 94 nissan altima and i just bought it a couple weeks ago and we have replaced everything that you could think of when i got the car it was running and we replaced the throttle sensor now it won't start so put the old one back in and yet it still doesn't start if you idle it it will stay on but once u let go of the pedal it's done for...i replaced the mass flow sensor ...oil...spark plugs..checked compression...all the vaccums.....what else could i do i can't drive it to go get diagnostic checked cuz it's not moving .....someone help me i need my car to work!! please!

could it be the ecu? what does that do ? would the car even start if the ecu was fried?

e-mail me if not replyed to this [email protected] someone help!

do you have the throttle position sensor in correctly? i know on the z32 they are adjustable. if you have it adjusted down to far, you would be starving the engine of air causing it to die.

explain wont start, is it a hard start, it takes forever to start. Or is it a no crank no start. , does it attempt to fire the engine or does it just crank.

If its a hard start check the MAF, and the TPS, and the IAC (Idle Air Control) If any of those are messed up then it will be a slow start or a hard crank start/ inconsestant start.

If its a no start no crank then it could be the starter, P/N switch(AT), or clutch safty start switch(MT), or battery.


attempter to fire, it could be the ignition system, fuel system, or the air intake system.

you will have to find how to properely adjust that sensor
also sometimes it can through out the ajustments for the aac valve and idle so look in to that
i also endured this problem with my 89 pulsar 1.8L
its a real pain in the @$$
