I changed the engine in my truck. Why won't it start?

Question

It came out of a Tahoe.  The other engine.  What do I do?

Answer 1

Start with the basic, you will need to rule out any mechanical problem, and check for spark, fuel pressure, 2008 GMC and a 2008 Tahoe engine specifications are the same, crank position sensor and cam and fuel pressure are the same specification, The only thing left is basic inspection
