nurkvinny Posted June 14, 2006 Report Share Posted June 14, 2006 I have a friend who is trying to figure out a no-start situation. 4.3 Auto. 167k miles Checked spark. Replaced Crank Position Sensor. Replaced regulator and fuel filter. Getting 40-50lbs fuel pressure. Any common issues with this year 4.3? Quote Link to comment Share on other sites More sharing options...

nurkvinny Posted June 14, 2006 Author Report Share Posted June 14, 2006 Thanks Rob, that is his guess. He's picking up a pump today (already swapped relays). Quote Link to comment Share on other sites More sharing options...
