HELP!: I locked up my engine
HELP!: I locked up my engine
Okay long story short, i was going to work today and left my neighborhood and as i accelerated (about 1/2 throttle) about to shift into second(automatic) my car goes bang (metal clank) and shut off and i put it in neutral and coasted to a stop. The motor is locked up, i think i might have bent a valve because everything from the exterior seemed to be intact. What is the best way of seeing what the problem is. My parents think i have no idea what happened but i told them that because there was no fluids leaking out(like if i shot a rod) then it would have to be something like a valve. What should i do???
Thats very un-common with a VQ motor....unless you were really very the pis* out of it... Have you tried cranking the motor after you stopped to see. It may have possibly been your trasmission taking a shi* on you.
Im not saying it "cant be the motor"....just unlikely.

if the crank won't turn when started either the engine's shot or the starter is. What if you try to roll start it: push it down the road in neutral, jump in, put it in 2nd and drop the clutch. Do the wheels screech into lock?
Gotta find some way to turn the engine over to see if it's seized.
You got oil right?!?

first its automatic, and yes i had oil, i will check it again in the morning but in theory if i had low oil the light would come on. I think its the motor but i maybe wrong. Whats the best way to check?

I agree with matty.. My money's on the transmission or starter. Give the starter a good wack and then try and start it.

ok well if it is the starter why would the motor go clunk and die??

Maybe he ment the tranny was about to shift itself. I would just assume he had it in D

ok..nevermind what i said then..but it still sounds like ure tranny sh*t the bed...take it to a tranny shop...they usually do free diagnosis....ide think a bent valve would still allow the engine to run, just not very effectivly.
and listen to nupe500...he had some good advice
oh and when my tranny went, my car started fine, but when i shifted into gear it just died(except i had to be in reverse, 2nd or higher gear cause i still had 1st). but basically if that happens to you its a good chance its ure tranny...are they any codes?

thats ntohign my starter went out in the middle of the races and iw as liek WTF DO I DO !!!!!!!!!!!!!!HEllla tripped out and my friend comes up and says pop ur hood...im liek huh? so i did anyway ad he hits somthign w a metal stick, iM LIKE WHAT TEH **** U DOIN! and he hits it again! and im like im bout to kcik your *** ...and he goes try to start it, and it STARTED!!!!!!!!!!!!!!!!!!!!!!! and ever since i never had any problems with it... =]

Got the page number?
I'm looking... Has to be related to the shift relay, and the same circuit controls the button which must be pressed before you get to "R" or out of "D" or "P".
For me it makes a horrendous grinding sound for ~ .0325 ms, then shuts off... and coasts.

and pull the front valve cover first to see if u see any damage from there

Have you tried cranking the motor over since the incident?

This seems to be a very expensive problem as I and and freind have both had inccidents very similar to this. First it can be your drive Timming chain,this happend to me in my Honda accord.I think it might be doubtful because our maximas chains are made to outlast the life of the car....and then theres your oil pressure, My friend and I were cruzing in his camry when his oil light came on and I told him to put oil in it and he said he would do it later, so he kept on driving 15 min. later we were on the freeway and all of a sudden the engine shut OFF IN THE CARPOOL LANE!!!! we were lucky enough to pull to the side...He got it towed to his mechanic and he said stright up your engine is seized due to low pressure and no oil so 2-3 of the pistons were metal to metal and and when it seized it broke some other stuff in there, I forgot what it was, but basically he had to get a new engine $1800. BOTH inccidents, the car just shut off like nothing while driving on the freeway...Maybe it could be something else Im not sure, but it sounds like one of these...
P.S DON'T KEEP TRYING TO START IT, THAT'LL ONLY MAKE THINGS WORSE

no i have only tried to start it once so hopefully i won't do more damage than is already done

When my Jeeps tranny went out the motor shut down, I coasted off the road and then started it up and thought I was saved! Nope, put it in gear and went nowhere..........
