I replaced my engine w/identical and no start 2010 3.3l Caravan
2010 Caravan - I replaced my engine on the weekend. 3.3l from an auto recycler and did a complete swap out. Took most of all the sensors, intake manifold, injectors, wiring harnesses off the old engine being replaced and put on the replacement engine. Van is a 2010 with engine now from a 2009 back in it - replacement engine has 162000 km.
Only sensors not swapped was the oil pressure sending unit, and the sensor on rear back exhaust manifold to my knowledge.
Put new injector seals, crank position sensor and new cam position sensor. (I believe the old engine sensors were all fine as no engine codes present on old engine before swapping it out - swapped out due to leaking head gasket)
New replacement engine spins over great lol. We can hear the fuel pump priming up but no start.
Notice though when key is turned over to start and released to run engine will keep cranking though (?????).
When we pull a spark plug they appear dry after cranking - appear to not be getting fuel - but yet fuel pump we can here it prime at initial key turn on (???).
Most experienced people I talk to say its a ground issues. I have cleaned the ground post and strap near the drivers side front on subframe as well as the engine ground strap and connection above the starter. Also have cleaned the strap/connections on the top engine mount as well.
Wiring harness appear fine and connections appear fine as well. We have went through them multiple times checking and double checking wiring cleaning and re-cleaning the ground straps mentioned above.
No codes present at all. (we did have one for cam position but replaced w/new sensor - so no codes now my scanner presently.
Any one have insight or words of wisdom......
