Just an update for those working with me to get my 01 LT back on the road after nearly 4 years. After going back in, injectors done (mr injector), checking all tank internal connections, replacing fuel pressure regulator, other odds and ends, she fired right up. I think the regulator was the culprit but will never know for sure and now it doesn’t really matter. All that’s left is bleed the brakes (new spieglers), button up the Tupperware, give her a good bath, and hit the road. Thanks all, for helping along the way. Great group!
