I've replaced a timing belt on a 1995 Honda Civic w/ a 1.5 liter engine also replaced water pump. Can I get specs on how to line up the timing marks please? Car won't turn over

timing belt book, public library, or use their database. if you repair engines and are asking this, thats a good place to verify your info. (and the belt must have broken).a technician would notice the position before disassembly. be aware,the valves may have bent. you may want the haynes manual. they can get you one.
where i live i can get their chilton manual at home by typing in my library card number. engine repair has alot to it when you are replacing that belt on that kind of car. i suggest reading the book. you will want seals and a water pump too. i hope the 4 exhaust valves did not get bent

On the Cam gear are three marks. On the face of the gear it should say "up", then you have three marks one at 3 o'clock one at 7 o'clock one at 9 o'clock. the one at 7 should align up with a mark on the block. Some have a raised semicircle and you line up the 7 o'clock mark on the cam with the far left hand end of that semicircle. Now on the crack end you have a mark at the 2 o'clock position and it lines up with a mark on the block. Do not turn the crank or the cam independent of one another, as the valves can be bent. Remove the spark plugs to ease turning the engine when needed. The engine will turn counterclockwise. Remove all necessary left hand front wheel, inner fender splash guard, covers, top engine mount. turn the engine until number 1 cyl. is at TDC compression stroke, and all timing marks align as noted. Remove the lower crankshaft bolt and pulley, and lower belt cover. Loosen tensioner bolt and push it out of your way and remove the belt. Put on the new timing belt in this order, crank sprocket, cam sprocket, water pump sprocket, tensioner. Belt must be tight on no tensioner side. Push the tensioner against the belt. Turn the engine 4 turns counterclockwise, until the timing marks realign, loosen the tensioner and turn the engine again 3 teeth, torque the tensioner to 30 flbs. reinstall all the mounts and covers. all should be good.

its located in front of engine , remove alternator and steering belts,
remove front engine cover , look for timing belt and fuel pump

Yes and 80,000 miles and change the water pump the same time too

this is a very hard procudure since you would need to disasemble the entire front of the engine, timing belt and all to remove the water pump. and if the belt is not put back together properly you can actually cause terminal engine failure

check your oil make sure the crank seal is ok that u didnt spill ur oil and blow it up. then check the timing belt - you may not have had the tension tight enough on the timing belt and it may have skipped a bit causing it to not fire. i think thats the most likely.

P1361 TDC Sensor Intermittent Interruption (I got this from Engine-Light-Help.com)
TDC should mean Top Dead Center.
It is the sensor that tells the computer the #1 cylinder piston is at the very top. And therefore, fires the spark plug.

Since the maintenance done above, I believe the the timing marks for the timing belt is not lined up properly. Being off by one tooth will cause this problem.

Not at all unusual for the timing belt to break and cause major mechanical problems inside of your engine. A failed timing belt can totally destroy your engine due to the extremely close clearences. That's why the strongly recommend a preventative replacement of the timing belts in all Hondas and Toyotas at specified mileage frequencies between 70,000 and 120,000 miles. Change the timing belt before it destroys the engine. You may now be at a point where only the Honda Dealer or authorized garage may be able to help diagnose the problem.

The only other thing could the the timing belt tensioner if there is any doubt. Here's the timing marks.

I know of no adjustment for the timing belt, they have a spring loaded tensioner that keeps the belt tight. Honda wants you to change the belt every 90,000 mile. I would always change the tensioner and the water pump, which is driven by the timing belt, at the same time. If there is any question about how long the belt has been on the engine, replace it, you do not want the belt to fail at highway speed.
