Nissan Repair: 03 nissan no spark, nissan frontier, wiring harness

Question
i have a 03 Nissan frontier that i just replaced the engine in with a used one and now it turns over fine but has no spark i tested the wires at the distributor and one has power any ideas?

Answer
Justin,

If the engine has no spark I would check the distributor.  If you have the distributor from the old engine switch it out with the new engine.  Also, be careful and check the wiring harness with what the old engine had and make sure all connections are the same.  If this fails email me back and we'll go from there.
