Hello, replaced my fuel injectors all new valve cover gaskets. Cleaned everything up. When doing all of the stuff timing belt popped off and it wasn't marked and when putting it back on the cam wheel (sprocket wear the belt sits on)turned over so turned over the engine to find TDC lined up the markers on the cams and crank and it sounds like it's really close to starting but it won't. When I have my foot on the gas I can keep it running for like 5 sec then it dies. Don't really know what to do from here any ideas or tips tricks would be great
Thanks Craig

 

Its on the timing belt. Its time to replace it and set the engine back up on top dead center. One of the cams is out of place when you realigned the old belt back.

 

Or, the crank is not at TDC. The painted lines are "aides" and it's possible to install a timing belt correctly without the painted lines being visible.

 

Or the belt or worn that needs to be replaced anyway. No "aides" on certain aftermarket belts, that do the same job as the overpriced stealership

 

I doubt it's the timing belt. Replacing them every 60,000 miles (the Severe Service spec) is a good idea, but the regular service spec is "don't bother replacing it." They don't degrade and make the cam timing off "a little"; they're good until they break.

The marks on the belt are just a convenience for installation, and not only do you not need them, you shouldn't rely on them anyway. As long the crank pulley and both cams are pointing straight up with tension on the belt, you're golden.

But if you seriously think you got the belt on wrong, you'll need to check it. And by the time you check it you might as well spend the $20 and put on a brand new belt.

So if it's not the timing belt, what is it? I'll bet one of your injectors is not opening, because you've got a loose connector. Many of us find that the years take their toll on the plastic part of the electrical connector to the injector. (Some of mine are held on with zip ties.) The easiest way to check is to pull the plugs; the wet ones are getting fuel. If you can get it running, pull the plug wires one at a time to find the cylinder not contributing. Last, you can use a mechanics stethoscope (or paper towel tube) to listen for the injector opening.
