I am needing help figuring out my power issue. I have a 2011 fiesta with the 1.6 gas engine. Head gasket was going so I swapped in a new (907 miles) engine from a 2015 fiesta. Got it in and hooked up but get a no spark issue. Swapped the CKP sensor, cam sensors, throttle body, and coil block from my old engine just in case. When I crank the engine, no rpms show up on the OBDII reader. Throws a random code now and again but nothing to do with cranking. When i try to start, the engine turns for about 2 to 3 seconds and then just stops cranking on its own. Everything worked perfect before swap, and all wires are hooked up so im at a loss. Cleaned up all tje grounds and removed paint under them also just im case it was a grounding issue. Anyone have some input??
