Changed the timing belt and had everything lined up. car started...couldn't tell how it really sounded cause i had the header open, exhaust didn't fit. but thats besides the point. but it started accelerating on its own. checked the throttle cable and saw that it was on too tight. so i went back and started it again, and it started but it died on its own after about 5 seconds. i tried to start it again but the cars not cranking. but i hear the starter?

Now heres the part that scares me. i went back to turn the crank manually, and nothing moves. The timing belt does not rotate around. the bolt just turns by itself. the pulleys are off right now. but it should still spin without the pulleys on. and i also noticed the cam gears don't line up any more.

anyone know what would cause this?

are you sure you followed the correct procedure for installing the belt and tensioning it properly?

Chiito4

yes i'm positive. making sure all the marks lined up. and then allow the tensioner to take up the slack at the end. butl nothing is turning right now and i have no idea where to start checking.

superacecardriver

sounds like your off timing or you bent a valve or vavles. Although I know these integras to be forgiving about being off a tooth from long past experience. lol. I would just start over.

Chiito4

the thing is that i'm just wondering what would cause everything to not be spinning. i hear the starter but the crank isn't turning. would the timing being off cause the crank pulley sprocket to not turn? its just weird to see everything at a stand still when i turn the key. the cam gears, timing belt, given they're all connected. just stumped cause i haven't found anything on here like this.

The starter directly turns the flywheel, which turns the crankshaft. If the starter spins, but the crankshaft isn't turning, then it could be the starter solenoid (the part that clicks the gear over to engage the flywheel's ring gear) may have taken a dump.

If the starter is turning the flywheel, but the crankshaft isn't spinning, then boy howdy you've got major problems, like the flywheel bolts have sheared off the crank

Put the key back in the crank when reassembling?

That's another good point, forgot about that one. Although, if the crank pulley bolt was properly tightened, it should still spin even without the woodruff key. Although it may not be/probably wasn't lined up correctly if the key wasn't in there.

Chiito4

Is there a way to check if either the starter or flywheel needs replacing?

Dude, you're going about this problem the wrong way. Put the damn car back together and go from there. Because honestly if you screwed up your flywheel or starter and sheared off all the teeth, you would've heard a loud series of grinds, bangs, and the engine would've violently shook the chassis of the car before it stalled out. With an open exhaust, I would assume you have improper o2 sensor readings which may in turn be causing your car to stall. Not to mention, you're not completely sure your car is timed properly. Just because you have all your marks matching doesn't mean your timing is dead on.

Chiito4

right, i can understand the timing could be off. not doubting that statement at all. but i'm wondering why the crank sprocket isn't spinning around and around when i turn the key. and when i manually crank it, only the bolt spins.

so should i just redo everything and put all the pulleys back on and try again?

On the end of the crankshaft, there is the timing belt sprocket, and then the crankshaft pulley, which goes on with a woodruff key and then the pulley bolt. Please tell us what is on there when you have been trying to crank it. Are all the pulleys and belts installed, and the bolt torqued down properly?

Look for simple solutions first. I would take a look at that key way on the crank pulley first.

The reason that the bolt is spinning is because it is attached to the crankshaft, which is spinning!
The cam sprocket is not attached to the crank in any way because you have forgotten to put that small rectangular Woodruff key into the slot on the crank/camsprocket.
This is not a difficult thing to understand and it has been suggested a number of times already. Stop looking for other possible problems that don't exist and go pull the crank bolt, install the key and be done with it. Hopefully you didn't bend any valves.

To the OP: Patrick is right on the money. The reason why his crank is spinning freely and not with the timing belt and cams is because of the woodruff key not in the slot. The woodruff key links the timing belt sprocket to the crankshaft. Once properly installed and bolted into place, then you will see the timing belt cycle along with the cams and gears.

If the crank has turned but the camshafts have not, you can pretty much bet on having bent valves.

LS stretch

you can put the crank pulley on and tighten it all the way down with the woodruff key missing, and/or the crank pulley not lined up properly with the two halfs of the woodruff key. the inside of the crank pulley has splines on it that that meet up with the splines on the crankshaft. you CAN put the crank pulley on the wrong way if the woodruff key is not installed, and then tighten the crank pulley bolt down all the way, and everything will still spin the same way it would if the woodruff key was installed in the place it is intended to be.. of course the timing would be TOTALLY off and the engine would not start.

Last time I checked my crank pulley did NOT have any splines in it. But it would still spin if the pulley bolt is torqued down.

Before the bolt is torqued down, there is nothing keeping the crank pulley from spinning on the shaft other than the woodruff key.

crxstylin

I do believe they have mini splines on them, so thin it is hard to notice. Either way, I would check for the woodruff key as stated by many people, assemble and try again

Then check the starter
Then the flywheel
Then the bottom end of the motor although I have not seen too many stock cars with a crankshaft broken in two

Shaved Honda B series Crank Pulley.....Just to end debate.

Okay yeah they have "mini-splines", but that does not keep the pulley in place if the woodruff key is gone. It can still spin on the crankshaft if the key is not in there. Before the pulley bolt is torqued down, the woodruff key is the only thing holding the crank pulley in place.

Chiito4

Thanks. Stuck the key in there with the sprocket and everything turned out great. engine started up and running smooth.

the thing is that i thought the key goes on after i put the concaved washer in. i didn't notice a key holding the sprocket and the crank bolt. so now i don't have a key thats holding the crank pulley and that crank bolt together. i'm assuming theres one there too since thats where i found it when i pulled it apart. but all the belts are flowing so i'm hoping everything stays tight.

thanks again for all the great answers!

scary :lol:

Don't bite your nails man... bad habit.

fergs96integra

You deffinately dodged a bullet on that one man. But anyways i am not sure i follow you on what you were saying about the key. The key that you are talking about is what holds the crank pulley on the crank keeps them spinning together as one. http://en.wikipedia.org/wiki/Woodruff_key this is a definition for you if that helps.
