Nissan Repair: Engine Starting, nissan maxima, nissan car

Question
1991 Nissan Maxima - start sequence is intermittent, engine does not turn, relays can be heard closing but no start.Continue a few more turns of the ignition key and then it starts. The battery has been checked, the negative cable from the battery has been changed, and  the starter has been changed. There are a few relays in the staritng system but unable to determine if any if failing.

Answer
you may have to replace your ignition switch.  check up the local junkyards or some Nissan car forums for a replacement part. shouldn't run you more than 20, 30 bux and it should fix your problem. i would also recheck your starter at a shop to be 100% positive this isn't the problem as well. good luck.
