My 99 navi started to mess up a few months ago. got gas and went to start it up. It tried then died. after 5 mins. it started with no probs. It did the no start thing a few more times since. I filled the tank a week ago and it did it again. After I got home it hs not restarted at all. checked fuses and relays all seem OK. replaced fuel filter left one line off and tunded the key afew times , Seems that no fuel is going thru filter . check fuel shut off on pass side kick board and it looked OK has not poped out the reset yet. What should I check next? or do I need to drain a FULL tank to replace a pump or strainer. Thank you for all your help.
