what was the koeo pressure? how many cycles to get there? what is the koer pressure? how much did the pressure drop in 5 minutes after you turned it off?

? koeo koer Pressure I think it drops to 30 or below when you turn key forward and pump kicks on it holds 40 for a few seconds then down to 30 or 32 I would have to recheck it don't remember while driving it is 34 or 36 and if you give it more gas it goes up to about 38 to 40 then levels back out to 36

I am not sure what you just said, but this is what it should be koeo=35-45. koer 25-35, koer with the vacuum line at the fuel pressure regualtor disconected 35-45. after you shut it off it should not drop more than about 8 psi in 5 minute

pull the vacuum line of the FPR and see if there is gas in it. there should not be

Ok Scanned the ecm got code 157 158 witch is for the Mass air did the test on mass air and it has the .02-2.0 truck sets at 1.48 so it proves it's not bad. says the o2's are running rich? How can they be rich any idea on that. I totally forgot about pulling the vac. line I will try that tomorrow if I get time. the koer koeo showed good on the scanner also.

The reason is the 02's are running rich is something upstream is not working correctly, but it sounds like your hopefully getting it figured out.

That is what I was thinking also. The hand held scanner said my timing is at 12 so I'm going to use the hand held to get it down to 10.
