any help appriciated:
well here the story, i have a 94 nissan sentra SE. i was taking my nephew to school early morning. i didn't give the car much time to warm up. i drove about 2/4th's a mile down the road. stopped at a stop sign. started driving smoothly shifting at normal Rpm's. the car has been raced alot. not latley though, and just the day before had an oil change. so i started to go and i was in 3rd gear. i down shifted to second floored it. didn't even come close to redline. when the i heard a pop in the engine compartment. it didn't sound loud but it sound like a backfire from the engine. right after that the engine shut off. i tryed to start it back up but the engine just cranked. everytime i tryed cranking it, it sound like a grinding noise comming from somewhere in the engine compartment just as soon as the car was about to fire up. the grinding noise sounded like it was preventing the car from starting. and it still does this. i did a self diagnosis check on the ECU and it showed me that there were no malfuntions. if anyone has some idea's as to what may be wrong. it would be greatly appriciated. thanks mike, palmdale, ca

tryed it...

i took off the cover, check the chain. it's on nice and snug, the rockers seemed to be intact perfectly i might add. i didn't check the plugs but they were recently changed aout 5,000 miles ago. even if the plugs went, do you think they would all go out, on all four cylinders at one time? because a car can run off of three cylinders hell even two, im not sure about one cylinder, i never tried that and i also tryed changing the plug wires, thinking maybe the wires wen't bad and maybe that's what happend. and still nothing.

cranks...

when i try to start the car, the motor cranks about 5 or 6 times and then a grinding noise. and after the grinding noise it cranks again about 5 or 6 times then just as the car is about to start up the grinding noise comes back into play. and it keeps reapeating it no matter how many time a try to start the car over. thank for all your help guys, see the thing is the car is going to be fixed. no matter what, That's my baby!!! (first car). but i wanted to know if anyone else out there has had the same problem and maybe they could give me a solution as to what it may be. to save me some $$$ in my pocket. instead of having to take it to a mechanic. but thanks alot to everyone who has giving me some insite as to what the problem may be.
thanks, mike

did that...

we tryed that already, me and my dad. he though that the spark was faint. he couldn't tell if the spark was good enough or not. now my new question is this. would this be an ignition problem or a problem with my distributer. my dad said i should change the electronic ignition. but i have no clue where it is. thanks sub
