Hello. I thought I would make this post and tell my story because I had not been able to find any good advice on the net.
The P0190 code became persistent, then the P0191 and 193. One day the car stalled at a critical intersection. It just suddenly started coughing and would crank but no start. Sometimes it would fire a little but not accelerate. Firemen pushed me off to the side so the car was at about a 15 degree angle to the left for an hour before the wrecker came. As soon as they got there, the car started up fine.
I put some more fresh fuel in and drove it home. The P0190 code led me to do a "full monte" and replace the three main things . . the fuel pressure sensor (on fuel rail) the fuel filter, and the in tank fuel pump. Got it all done yesterday and thought I would share the experience.
So, I am an old aviator and my philosophy is to "do it all" and eliminate any possible failure points. This is why I did all three things. Oddly, on my 21 yo car with 87,000 miles, the fuel filter had never been replaced! Should you choose to do the fuel pump, be prepared and get the entire pump assembly and lines. It is not difficult to run the two scavenge lines into the drivers side scavenge tank. They plug onto the footing of the sender unit. I used a tie wrap to hold both the lines together and a metal coat hanger as a fish to get them over. The new pump went in easily into the right side of the tank. There is no specifically designated position for placement BUT there are tabs on both the main filter and the scavenge unit. Make sure those tabs go into the tabs on the housing. This is CRITICAL. I bought the non oem pump at ORiley, cheaper & same warranty as Delphi. Second pic is of scavange assembly (drivers side of tank). You can see where the lines mount. I did scavenge side before doing main pump BUT you can do main pump first as long as you make sure those scavenge lines are in the left side of tank.
I have posted a few pictures. Hope this helps.
