    aaaaaaggggghhhhhhhh just a guess–your out of time???gotta go to mechanics 101 and get timing mark/#1 tdc and dist rotor on one all at the same time/covers off and make sure your on the fire stroke

    the timing will need to be set with a timing light,you’ll need to get someone (mechanic) to do this for you.

    yep what ken said. but you’ll be lucky if you havent already severely damaged your engine. if you cranked it over with the timing out, there is a good chance you wouldve smashed your pistons into the valves, bending them :(

    here is the big question did you time the cam to crank correctly or is it 180 out. and then is the distributor the same, 180 out. either one will give you no response out of the cranking. adjust lugs 180 and see if that rectifies the problem. if it does great, if not you get to go way back in and double check the timing belt. if you are lucky it is an air cooled block with so much less to disturb.

    You need to check that the valve timing and the ignition timing were done properly. It would be easy to check the ignition timing first. Back track what you did and check that you were using the correct timing marks.

    Here’s a BB discussion on a similar problem with an 88 944. I hope you can find an answer here.

    Make sure your timing marks line up first before you crank the motor anymore. There is one on the flywheel and one on the cam pulley. If you’re using any marks other than those two for the timing, that would be your issue. If that checks out, use an inductive timing light to make sure your plugs are firing when they should be. If not, check the cap to make sure the wires go to the right plug. I can’t remember if there is a flat on the rotor but make sure you put the screw back in the rotor. Did you replace the balance shaft belt too? becuase you should have. If not you’re asking for trouble and you need to cough up the $100 for a new belt now before you get any further. Back to your spark issue, it could also be the alarm module. If you’ve disconnected the battery the alarm module sometimes wont let the car start. Check clarks-garage.com for info on bypassing the alarm. Another note, on the flywheel, there will be a wide groove and a line. The line is the timing mark not the wide groove. If it ran before you changed the belt, and didn’t sit for very long, it should run now. If it sat for awhile your issue may be one of the many other sensors on that motor.

    The Porsche 944 is a very delicate procedure in replacing the timing belt.

    For one, before you do anything, crank the engine over by hand once you’re finished and make sure that NONE OF the valves interfere with each other. You should not EVER try and crank the engine on these cars during a timing belt procedure until you are 100% done, have cranked the engine by hand and verified there is no interference to the valves.

    Second… recheck your work and double check your marks. Don’t worry about a timing light as it’s useless on these cars to replace the timing belt.

    Aside from that there is no ignition timing to set on these cars as it is all done by the DME and physically by the timing setup. So the only factors in the ignition if you replaced them is making sure it was all attached correctly or broke something.

    Here is a link to the full procedure on clarks-garage.com – follow it to the T on replacing your timing belt. You can’t go wrong with it. If you don’t have a proper belt tension tool to check the tension I highly recommend it so you don’t end up having any issues with harming the water pump and stretching a belt or skipping a tooth and replacing valves.

    If the engine will not turn over you have likely disconnected or bumped a ground somewhere that has caused it to lose power somewhere in the ignition system.

    Again – double check the timing marks using the clarks garage manual. Make sure the flywheel is locked when doing this, and make sure all the marks line up, check all your grounds in case you accidentally bumped or disconnected something and turn the engine over by hand. Do NOT attempt to start it without doing this first. The last thing you want to do is replace valves. Again, I cannot caution this enough.

    Once you have verified all these things and if it does not still start then check the no start conditions page on clarks-garage, it has all the potentials of what can cause a no start condition as well as what kind of condition it is… here is that link as well.

    Between me and my husband we’ve owned more MP3 players over the years than I can count, including Sansas, iRivers, iPods (classic & touch), the Ibiza Rhapsody, etc. But, the last few years I’ve settled down to one line of players. Why? Because I was happy to discover how well-designed and fun to use the underappreciated (and widely mocked) Zunes are.

    Hands down, Apple’s app store wins by a mile. It’s a huge selection of all sorts of apps vs a rather sad selection of a handful for Zune. Microsoft has plans, especially in the realm of games, but I’m not sure I’d want to bet on the future if this aspect is important to you. The iPod is a much better choice in that case.

    The new Zune browser is surprisingly good, but not as good as the iPod’s. It works well, but isn’t as fast as Safari, and has a clunkier interface. If you occasionally plan on using the web browser that’s not an issue, but if you’re planning to browse the web alot from your PMP then the iPod’s larger screen and better browser may be important.

    The Zune concentrates on being a Portable Media Player. Not a web browser. Not a game machine. Maybe in the future it’ll do even better in those areas, but for now it’s a fantastic way to organize and listen to your music and videos, and is without peer in that regard. The iPod’s strengths are its web browsing and apps. If those sound more compelling, perhaps it is your best choice.

    Hello there I’m getting a technical obstacle browsing your site, I’m receiving 500 pages very often, I’m not much too clear about why however when I refresh the webpage it comes alright.

    Can I have a word of advice? I believe youve got sth great here. Yet imagine if you also added a couple links to a site which supports what youre you said? Or possibly you can provide us with something to check out, something that would certainly link up what exactly you’re saying, something concrete?
