Hey guys! Well I scanned a customers car and I retrieved a code don't remember if it was P0600 or P0300. Random cylinder misfire. The car is a 2000 3.8. I didn't notice anything wrong besides the fuel pump buzzing on and off. I was getting like 45 psi of fuel at idle and 50 wot. I was constantly looking at the gauge but there was no fuel pressure drop. The car only has about 50k miles. I told the guy we should try and replace the pump first. Is there any common problems related to this code?
