2005 dodge neon cranks but wont start - 1997 Dodge Neon

Hello, If it just cranks and not starting at all can be several things to look at. A engine to run needs fuel, spark, compression, air. BUT here is what I would first do, if you check to see if you have spark, and fuel, most likely it could be the crank sensor. If no codes come up on dash. There is so many things it could be. Just take one step at a time. See if your getting fuel, if you smell fuel, like flooded, then its getting fuel, otherwise could be fuel pump not working, If pulling a plug and keep it in plug sleeve and set next to medal screw on block, and have someone turn key, to see if you see spark. If spark then getting spark, Then were back to a couple things.... Crank sensor went out, that will cause to crank and not start, if cam sensor went out, it would still run, but just like ****. Next if still cranks and wont start, could be the timing chain missed a slot, which means could of bent a valve or stuck valve. Dont panic yet, just like I said start with first and always fuel, and also dont forget fuse panel for fuel relay fuse or fuel pump fuse to see if good. Keep me posted as i will try and help you along the way, Mike
