Re: Fuel rail pressure still too low AFTER replacing sensor, fuel pump, PEM and filter

Hi everyone- I wanted to let everyone know I finally got it all the way fixed! I finally decided one last try....I swapped out the brand new PEM that I had bought and installed (previous to the videos above) for one from an identical car at the junkyard, and it works. Flawlessly. Turns out the brand...

Need some hose and clamps to rig it but it will show where the problem is.
Do you mean at the Schrader valve just before the fuel filter? Or a different location?

Re: Fuel rail pressure still too low AFTER replacing sensor, fuel pump, PEM and filter

Hello all- Seeing as how either way the first replacement fuel pump was crappy/broken and either way the problem was not solved, I acquired and installed yet another new fuel pump. With everything I have learned so far the process went much smoother this time and I came up with a good way to do the ...

Re: Fuel rail pressure still too low AFTER replacing sensor, fuel pump, PEM and filter

We have indeed seen in-tank fuel hose kink, however you appear to say that direct power to the pump seems to solve the problem. Would suggest a fuel pressure gauge at the schrader valve to read the pressure live. The replacement PEM was used unit ? Always possible someone sold an already faulty one...

Re: Fuel rail pressure still too low AFTER replacing sensor, fuel pump, PEM and filter

Hey all- I wanted to provide an update and thank you all for your replies. As of today we have pulled and re-re-installed the new pump. I had drained the tank almost entirely, I added back in one gallon cause it would not start at all. After adding the one gallon of gas, it now starts but won't hold...

Re: Fuel rail pressure still too low AFTER replacing sensor, fuel pump, PEM and filter

Hi abscate, thank you for replying. What I don't get about that is...I did use a messenger line to pull the hoses back through from the passenger side to the driver's side to reconnect to the sender side. I followed the techinique that we've probably all seen in several videos of tying it to the old...

Fuel rail pressure still too low AFTER replacing sensor, fuel pump, PEM and filter

Hello all- I'm at my wit's end. The vehicle is a 2005 XC70 Turbo AWD with approximately 150K miles. Original problem (from a few weeks ago): wife drives home one night with everything seeming fine and shuts the car off. Next day, it will crank readily but no start, no run. Weeks of analysis and repa...
