I changed the fuel pump, we can hear the pump working when we cycle the key, which was something we didn't hear before. We also changed the fuel filter. When we removed the old filter there was a lot of dark, almost black, watery gas that poured out of the filter. We did not check the pressure of the pump once we replaced the pump, so I'm not sure if the pump is putting out enough pressure.
Once we had everything back together we started the truck and it fired right up. I drove it out of the shop and parked it and turned it off, everything was fine. After about 3 min (I cleaned up the shop) I took it out on the road to test it out. I ran fine but as I slowed down to turn a corner, it would drop RPM's down to about 400. My truck struggled to hold the idle. I drove out a little further and again making a turn I loss RPM's and it died mid turn.
I'm going to check the PSI to make sure its sending out 55-62 PSI. My question is, what should I look for next if we have the right amount of pressure? It has a full tank of gas. We are also going put a siphon down to the bottom of the tank to see if we have clean gas.
Any suggestions are greatly appreciated.
