Welcome to the Nation.I'm trying to find if it possible to swap engines.ive got a07 Chevy Colorado 3.7 that shit the bed.i have a04 3.5 and a 08 2.9 how difficult would it be to drop one of these into my 07
I replaced the valve springs for to let lose and broke I replaced all and put new head gasket put engine back to gather and in to find I have power to the coils but nothing coming.out for spark only cranks.Welcome to the Nation.
I don't think the mechanics of a swap will be that problematic. The issues, that will have you pulling your hair out, will be the electronics. The wire harnesses for all three of the engines mentioned, are different. When I say different, I mean that they each have different connectors for the PCM. If you chose the 2.9, you would have to try to use a 2008 PCM. Whether or not that would work in your 2007 is an open question. The PCM will need to be programmed. It's doubtful that the 2004 3.5/PCM would even work in your 2007. Before getting in too deep I would suggest that you find someone with automotive programming experience and get their opinion. You are going to need a programmer, anyway you go with a swap.
Just curious, what caused the 3.7 engine to be beyond repair?

I'm not sure I understand what you are saying. It appears that you replaced valve springs and now the truck won't start. Now the engine cranks, but there is no spark plug firing? If the engine sounds normal when cranking and the problem, at this time, just appears to be electrical, why are you planning on replacing it?I replaced the valve springs for to let lose and broke I replaced all and put new head gasket put engine back to gather and in to find I have power to the coils but nothing coming.out for spark only cranks.
