i have a problem i recently swapped out engines from a automatic 97 eclipse rs to my manual 96 eclipse rs , all the sensors matched but 3 of them, one to the coil pack,the one by the thermostat and the crank positioning sensor on the bottom of the block in the back, now we rewired a new plug for the crank positioning sensor and the color didnt even match just 2 wires had lines going thru them and one solid so i just layed the sensor flat from left to right and wired them in becuz the wire on the harness and the new plug in the was black, and i put the coil pack from the other engine on there so it can plug in , now i aint gettin no spark or no fuel , the engine is trying to turn over and the intake is like suckin my hand thats how strong it is , so we tested the wired going to the coil pack while im cranking and the test light is not lighting , could this be a pcm problem? becuz the last engine that was in there the timing belt snapped and u know what happens after that, but at the time i didnt look under the hood when i was on the side of the road i just tryed to start it again , could somethin have shorted becuz the engine was already seized? please someone help i been at this for weeks , its not the timing , its set at TDC

Any time you swap engines it's best to keep the original sensors and coil.
The ECU isn't reading something right because of a wrong sensor or hacked wires that you're trying to match up.

Exactly. You should have used the sensors from the old engine. If you have them still I would reconnect your wiring back to the way it was stock and just hook up the old sensors and I bet your car will start.
