Well, another trip that didn't make it out of the driveway. Engine died, STOP SAFELY NOW, yadda, yadda, yadda. So I pop the hood expecting that F9 is blown again. Pull it and it is fine. Check ALL the fuses and relays and everything is kosher. Get back in and pull up the DTC xgauge and it is blank! Hmm, remember that if there is more than one DTC then the FEH will send them in a multi-frame message so the xgauge coding has to be changed. Have 3 PCM DTCs and EIGHT TCM DTCs! Yow. Check them out and most are "informational." So, remembering what the dealer did I check the fuel pressure.... ZERO. I code up an xgauge for Desired Fuel Pressure (0x1670 mode 0x22 PID) and it reads 39.8 psi. Turn the key to start and fuel pressure blips up to 5 or so psi before dropping back to 0. So fuel pump or fuel pump driver module not working. Lift up the left rear seat, open the panel, pull the connector to the fuel pump. Use OSC to turn the fuel pump on and read 11V at the fuel pump. So, FPDM is probably OK. Re-connect harness, command pump on again and nada. No noise, no fuel pressure. Gotta be a bad fuel pump. Woulda thought that the short on the FPDM input would have taken it out instead of the fuel pump, but so it goes. Order fuel pump online, lists for $165 but discounted price is $109. Place order, get call the next day saying the part has been superceded and the new list price is $465, $300 my price. Asks if I still want it, reply can you find one of the old $109 pumps? Guy laughs but says he'll try. Next day calls and says he found one, $115 delivered. Grab it and UPS shows up at the door 3 days later. Pull the old pump out, clean up O-ring area with q-tip and alcohol and install new pump. Tank cut out is razor sharp and get several cuts while putting in the new pump. Luckily had alcohol and q-tips handy. Button it up, turn the key to on and look at the SG. Desired FP 39.8, measured FP 52.1. Woo-hoo! Start the FEH and drive away happy. Did the short that blew F9 kill the fuel pump, or just a big coincidence? Parts guy said that the old fuel pumps on the first gen FEH did go out on occasion so I guess 94k miles and a short on the input of the FPDM might have combined to take it out. Next time I doubt any of the $109 pumps will still be around and the new, and I assume improved, $300 dollar pumps will be the only choice. Figure with a $465 list on the new pump and some labor it would be a $600 or more fix from the dealer. SO, if anybody gets a blank DTC xgauge, PM me and I'll walk you through the details. Blank DTC means a problem, no DTCs would show 0000.
