heres the deal
i was driving down the road at low rev and the timing belt broke!
yeah!
well nothing sounded horrible and it didnt seem like anything bent, hopefully
so i got started changing the timing belt and did all the other belts

now heres the problem
the car wont start. It turns over and over but does not fire.

I changed all the belts even the balance shaft belt, I aligned all of the timing marks on the crank the cams and the oil pump
originally it slipped out of time and backfired as i turned it over and still did not fire, i realligned everything and now the car sounds smooth when it turns over but it still does not fire.

i am almost 100percent positive it is in time, but if theres a better way to ckeck...

there is also a clicking noise near the battery when i turn the key on and off

i checked and i am getting spark across all cylinders through the wires, i have a full tank of gas, and i charged the battery even.

so what else could it be, starter, fuel, something worse?

please respond and feel free to PM me or IM me or whatever you do.
thanks
 
ted, you were driving down the road, and youre timing belt SNAPPED?
me thinks you just spent alot of time and money for nothing.
time for some engine shopping, do a compression test first i suppose, but 99% chances are the engine is gone.
 
Dude, if you were driving you can automatically assume that you bent valves. There is no way those valves sealed themselves before atleast one set of pistons hit a set(2) of valves. my.02 cents.
 
Compression test will confirm what everyone is telling you. Your valves are bent. If the DSM gods have smiled down upon you, you might be able to get away with just replacing the head.
 
im bored at school so it happens

so basically no matter what something internal is f'd up if the belt breaks,
theres not any ticking or pinging anything like that when it turns over, and there wasnt any noise when the belt broke

wouldnt i hear something if the piston demolished everything?

would there be something malfunctioning internally that would allow it to turn over and not fire?
 
First off, do the compression test. That will tell you for sure whether or not you bent a valve or not. If compression is good, then check for spark and fuel for each cylinder. If you BROKE valves, then yeah, you definitely would've heard something.
 
Do the compression test, I guarantee you will start dialing up zeros ... remember the motor is turning relatively quickly even at idle, there is basically no chance you can shut the motor off fast enough to prevent bent valves ... at this point I would just hope that there is no damage to the pistons so you can get away with just a head rebuild.
 
yeah i was just wondering if maybe i lucked out but i was thinking the worst too
i dont have the tools to do a compression test. is that something that can be picked up at a local parts store?

im really not too worried about the parts replacement bc i get all wholesale parts anyway but i am more worried about the time its going to take. I would like to diagnose the problem and fix it not fix a couple things to get to the problem

thanks for the help
i will do the comp test this weekend when i get home from school and keep you all updated
 
i bought a compression gauge and did the test and dialed in zeros on the first 3 cylinders but gave up and didnt try 4 since i know i am just goin to get a new head so it will all be replaced anyway. So heres the deal
i want to double check myself that i did the test right.
i unhooked all of the plug wires and undid the intake pipe and held the throttle body at WOT and then had someone turn the ignition over and try to start it
so the gauge never moved and i got zeros. i just want to make sure that i did the test right and im not missing anything before i got ahead and tear down the head
please reply as soon as possible bc i am starting in the morning.
thanks everyone,
anyone with a good quality complete head let me know
 
OK, dude, you remove all the spark plugs. Then you put the compression tester in the spark plug hole for #1 spark plug and crank the motor over with the throttle wide open until the compression stroke comes three times. Record the pressure, reset the guage, go to the next plug hole and do it again. Is that what you did?

Sounds to me like you missed the whole "diagnosis" phase before you took the time to replace the timing belt.

yeah the diagnosis phase is what i am doing now and by the way itd be kind of hard to turn the engine over and do a compression test with no timing belt wouldn't it.

I did do the process as you said and as the directions would indicate. I dialed in zeros on the test so i guess i'll break down the head and see whats going on.

I'll keep you all updated. Any advice would be appreciated. Thanks

Please keep in mind that these engines have what is known as an inteference design, meaning that the same space that a valve would occupy when it's open is the same space that a piston occupies at top dead center. Doing this compression test with no timing belt on only puts your engine at risk of being damaged even further because the pistons may still be slamming into open valves, even if they are already bent.

It's a surefire bet that your head is done for. Pull the head, repair it or find a replacement, and while the head is off, make sure the pistons weren't heavily damaged by this catastrophic engine failure.
 
thats the plan
i found a member on here who has a ported and polished head so i am going to pick that up and do the swap

thinking while everything is pulled i will go ahead and upgrade the turbo too. Anyone with a 14b they want to get rid of let me know
thanks
 
I took everything off the engine and got the head removed only to find nearly every valve bent to heck

my pistons also are scored where the valves hit and made nice dents
so i guess i will be taking the engine out and redoing the bottom end as well
wish me luck
thanks

I feel you man and good luck. I bough a 95 gsx from a guy with a blown engine had no idea why it wouldnt start. I got it home and found out that the timing belt broke on it. It complety runing the head, and pistons. Actually put holes in the pistions, cracked the valve guides and the whole 9 yards. I decide to do the 6 bolt swap. If you want to just keep your motor i recomend the top line rebuild kit. Its 500 dollars and it includes new pistons, rings, bearings, oil pump and housing and all the gasekets and seals you need. I put that in my 6 bolt and its seems to be doing good.

This is one of the many places to buy the kit from (this is where i got mine from)
