So I bought an 05 ram 4.7 slt with a blown engine. I bought another engine with only 65,000 from a wrecked Dakota. I was told it was the same. Anyways after swapping in the engine I tried to start it, and BOOM!!!, the air filter box blew up. I talked to the guy that sold me the engine, he's an old friend, and promises that the engine was running great when it was in the other truck. But now it tries to start but it won't. I know it has fuel and spark.
Any suggestions will be appreciated.
Thanks in advance.
Try checking the timing, make sure the cams are correct and then look at the firing order of the spark plugs, they may be scrambled, or the fuel injector's wiring may be scrambled. If the air box got the big kaboom, a valve may be open when the spark plug fires.
Hope that gives you somewhere helpful to start.
Don't worry, if you can do a swap, you will figure this out.
I checked for codes but none came up. I changed the cam position sensor, and nothing. But now with the new cps, code p0340 (cam sensor) is appearing on my scanner. I reset the computer and the code comes back after cranking.
