Re previous question re no fuel... Discovered there is power to the pump.

What is your question?

Indeed, after feeling the relay close, and listening at the filler, I can hear the pump running, but none in the high pressure line at the injectors. So next, try & check return line at injector area, then crawling under and checking hoses & connections, which fortunately are on the sides of the tank. Any suggestions are more than welcome, indeed, hoped for. Thanks, Tom

OK - I sure will - first thing tomorrow... Thanks so much for replying - this thing's been driving me nuts. I'll let you know. thanks, Tom PS - looks like the intake plenum comes off first to replace the regulator - right? I sure hope I find splits or cracks where hose to tank attaches......and that does it... But - Thanks again...

Again - certainly appreciate your responses... And indeed, does the plenum have to come off first? And which one is the vacuum line - OK, I think I see, in the good old Haynes manual, on the "upstream" side of the regulator....so no doubt, plenum off.... OK - mid afternoon... Today, checked vacuum tube to regulator - very solid, no gas... gas in return line as supposed to be. Next day - I'll be damned - Went to pay the big bucks for computerized scan, and the guy asked about fuel filter - Never gave it a thought.. Maybe modern cars, the ECU makes up for it, and hides the symptoms I used to recognize in the old days... So - haven't put in yet, but maybe all this trouble for a lousy $6.00 filter... makes sense - maybe never replace since new..... arghhhh tried to start, and the damn thing fired right up - hadn't tried it recently... I didn't do a thing to change it... so, dammit, still don't know the problem... could still be the regulator, or any of the sensors - since all that goes through the ECU and tells the pump to run...Since it's pre-96, can't get a free computer check - different plug in spot - maybe I'll bite the bullit and pay a garage $50 to use their old adapter and get the fault readout. I tried the analog volt meter method, and nothing... So - crap.....any comments? But, thanks again, Tom PS - with the help of a long, thin screw driver, got the vacuum tube off the regulator without removing the plenum - a big relief...
