Message	:( I drove Saturday, Sunday, all the way to and from work today. No problems. Better than ever. More power in the upper range. But when I got home, I left about 30 minutes later to pick up a kid and it cut out once as I was slowly (traffic) entering a highway. Then, I decided to alleviate fuel pressure just to check everything out, and I could not get the pressure to go all the way down!!! WTFreak? I cranked several times with relay unplugged. I've never had issues with that. Car just kept running (very low rpm, stumbling). Waited 30 minutes, cranked again. Waited 30. Still was reading between 2-5 psi. Could this maybe be indicating a faulty FPR? Got stuck closed? Maybe other times stuck open causing the stall? VISIT thumper300zx.com for PICS and TECH PAGES
