My 94 nissan pathfinder se v6 won't start, I recently replaced the power steering pump and it started and ran for about a week but it was a little hesitant. Now it won't start, it just cranks but does not start. Its gettting fuel but I do not think it is getting fire. Any help?

Have you had a tune-up recently?

If you have spare plug that is good then just connect it to one of the plug wires and see if you have spark.

If you test a few of the wires and none of them have spark then it may be the distributor.

How many miles on the vehicle?

If not, then replace the plugs and maybe the wires if they are the original ones.
