Question about 1997 Dodge Neon
I have a 97' dodge neon, DOHC, with a new junk yard engine in it with about 65,000 miles on it.
Old engine had 145,000 miles on it but water pump froze up and broke timing belt. you know the rest of the story with that engine.
new engine is in and everything. junk yard said it's out of a 98' neon. when i try to start it, it gluggs like it wants to start but just wont. if i give it a little bit of gas while trying to start it it will start up but runs really rough and will idle but still very rough and it sounds like the lifters and knocking or something.
I turned the engine over by hand and it doesn't feel like the valves are hitting the piston. WTF should i do?
Only guesses are that the gas is bad from sitting there for almost a year at least now but it smells fine. i have the fuel rail off of my old engine and i'm going to swap that tomorrow. i'm guessing it's a timing issue but if that were the case it being a 0 tolerance engine it would have blown itself by now, wouldn't it have?
How old was the gas in your car? How long have you had it running for? Also have you checked the codes on it? Once I have more information I can give you a better solution. Make sure the oil is at the right level, but I assume you have checked that.

Check it for codes. Probably multiple cylider misfire. That's caused by not using Champion plugs,like from the factory or a bad coil pack. Also, you can try changing the cam sensor from your old engine. Also,make sure the throttle bodies are the same & all vaccuum lines are connected. There's a hidden one under the throttle body. Also make sure the cat converter didn't melt solid from overheating due to the bad water pump on the old engine. You can do that by punching a small hole in the exhaust before the cat & check for anything over 1lb of back pressure. Check the fuel pressure as well. Remember all junkyards say it only has x miles. Don't believe it unless you're related. You can do a compression check to see if it has bent valves. If it's smoking black,make sure the map sensor is connected properly. Lastly,& hopefully not, make sure you're not even off a half tooth on that timing belt!!
