Engine will not start after replaced - 2010 Dodge Challenger

First off ,no start how ? crank - no - start - when you turn the key to the start position the engine cranks -starter engages an spins engine but won't start an run or you have a no - crank - no - start . engine does not spin . which of these is your engine doing ?

its possible that you froze the engine replace it

change the starter or replace the starter solenoid,and make sure when you replace the engine you didnt pinch a wire between the engine block and the transmission

replace coolant temp. sensor , disconnect coolant sensor plug after engine is at running temp. ,shut engine off then restart ,if engine starts fine, replace coolant sensor

Does the engine have a distributor on it ??? if so see if thats wet, you will need to clean and dry that out.

if its fuel injected take a hair dryer and aim it at the injector rail where the injectors stick into the engine and dry that a bit..

have you had the glow plugs checked or replaced? the engine light'wait to start is not a joke. it means the engine glow plugs need time to heat the cylinders to max. heat to fire the engine to start. if you use either or strting fluid to start the engine in cold weather,be careful,the motor will get addicted to the starting fluid. sounds like you've not waited on the wait to start light goes off before cranking the engine.replace the glow plugs 1st and then wait before the wait to start light goes off! it's a common mistake.however the cost of glow plug replacement will be a constant reminder to wait to start. glow plugs cost about $100.00 plus labor.been there myself!! you can start engine easily in a/m with either or regular starting fluid, but please take this to heart,it's easier to replace glow plugs,than engine you can use starting fluid by spraying into the air intake of motor once,twice, but from there on,you're on your own! thank you for choosing fixya.com

Engine is difficult to start when cold

1. Check the battery condition, battery state of charge and starter motor current draw. Replace the battery if marginal and the starter motor if the current draw is beyond specification.
2. Check the battery cable condition. Clean the battery terminals and replace corroded or damaged cables.
3. Check the fuel system for proper operation. A fuel pump with insufficient fuel pressure or clogged injectors should be replaced.
4. Check the engine's tune-up status. Note the tune-up specifications and check for items such as severely worn spark plugs; adjust or replace as needed. On vehicles with manually adjusted valve clearances, check for tight valves and adjust to specification.
5. Check for a failed coolant temperature sensor, and replace if out of specification.
6. heck the operation of the engine management systems for fuel and ignition; repair or replace failed components as necessary.

Engine is difficult to start when hot

1. Check the air filter and air intake system. Replace the air filter if it is dirty or contaminated. Check the fresh air intake system for restrictions or blockage.
2. Check for loose or deteriorated engine grounds and clean, tighten or replace as needed.
3. Check for needed maintenance. Inspect tune-up and service related items such as spark plugs and engine oil condition, and check the operation of the engine fuel and ignition management system.

Have you checked the fuel pressure? It sounds like a bad fuel pump.

take dist cap off and remove rotor look for carbon tracking on it. have a lot of problems with no start cuz rotor is worn and fire shoots straight thru
