I have a 95 Nissan p/u in very good condition. I have done most of my own maintenance. As for the starting problem, it is usually the starter and alternators every 4 years. This time I have detected a new problem. I am almost positive of the source since it is starting sometimes and not others (the starter and alternators are both less than 2 years old).
I believe, though have not confirmed yet, that the problem is probably the relay switch between the clutch pedal and the starter. Since it will start sometimes after a couple of pumps on the clutch, this makes the most sense. It might be worth investigating this on your own truck. It is a cheap and easy fix. I am going to go check it out today since I finally have time to!!!
It seems to me that a lot of you are experiencing the same issues. Intermittant starts. Good luck!!! Not bad for a girl, eh?
