[QUOTE="jjk23, post: 15794195, member: 163506"] OP, You are doing the right thing by checking the easy things first. You mentioned observing zero fuel pressure using your OBD app + tablet. Did you check fuel pressure before and after key-up? [I assume your OBD app can read live data.] If you have not checked fuel pressure in both cases, I would do so. [If you can hear the pumps priming following key-up, the pumps are getting power.] If your tool cannot read live data and you are still on the stock fuel rails, you could pick up a simple fuel pressure test kit. The Schrader valve is located on the passenger-side fuel rail. The last items to check before dropping the tank would be your FPDM and connections at the voltage booster. If you have a spare FPDM or have a friend that has one, try it out. The absolute last thing before dropping the tank: Your previous comment regarding the "cloud of fuel" makes me curious about your new FRPS. Go back to the parts store and exchange the FRPS for another one. Install the new FRPS and make sure your battery is completely charged before attempting to start the car. It would not hurt to pull all the spark plugs and let the car sit for an hour or two [just make sure all the fuel is out of the cylinders]. If this lands you in the same position as before, be prepared to drop the tank. Luckily, it sounds like you have had the tank down before. I would just get one or two friends and some Pig Mat. Did the PPRV delete kit from LFP use worm-gear clamps or Oetiker clamps? I recommend installing some Oetiker clamps if you are given the chance. They are easy to install and are very resilient against vibration. You will get this sorted out, just may take a day or two. Good luck! [/QUOTE]
