so the other day i was parking my dad's truck in the garage and for no reason it died out on me while i was in reverse so i popped it in nuetrul and started the truck. which started up ok the truck has about 115,000 miles on it or so. before the warranty expired the fuel pump was replaced and so where the cylinder heads but that was when the truck had about 64,200 something miles. it hasn't had a tune up since then. do you guys think i should do a tune up first before suspecting the fuel pump possibley going bad? and another thing i noticed was whenever i use the turn signal/hazards the light will flash for a few seconds and then freeze and the turn signal/hazard light will stay on until i turn them off. i'm thinking maybe the relay is going bad but i could be wrong. any suggestion on how to fix this? thanks.
