Hello everyone. It’s been a long time since I’ve posted. I’ve had children and business has taken me away from my Buick hobby for a long time. The Buick’s have suffered from neglecf. The gs is running well and I put it in storage last month after an undercarriage detail. Still needs paint again but that will be another day. The Tyype was set outside after the paint job got ruined by an automatic gate crushing quarter panel 5 days after job was done, 7 years ago. I never put the weatherstripping back on I was so disgusted. Anyhow I want to drive it again, and get it back to where it once was. So I bought a tt e85 chip, 80 lbs injectors, new acufab regulator, and a dw?320 pump, new tank, sending unit, etc and got it running again this time on e85. Moved it around the lot and that’s it about a year ago. It ran and ran well, although i didn’t road test it. Started it recently and added fuel again, so now maybe 10 gals. It cranks and runs (have console switch for fuel pump), but will idle/run for exactly 15 mins and then stalls. Fuel pump shuts off. Hotwire relay in trunk licks on when I flip switch, but no pump. Let it sit for a little while and flip switch, bingo head pump and it will start and run again for 15 mins, dies same story. I feel there is high resistance building in the electrical circuit but haven’t tried tracing it yet. Any ideas? I also have a problem with too much fuel pressure at idle, regulator can’t be dialed down enough to drop below 55 psi line on or off. Think return line is too small (factory tubing). Wanted to get it running well enough to go round the block and get trim reinstalled, screw the bodywork for now. Thanks for your insight.
