Desert: I can't edit posts or manage in the DIY section at all, I think only you can....

The plugged line theory is why I said pull the line at the fuel pump and see if it pumps, then reconnect it and check it at the firewall again, if it's not working at the firewall then you've got a plugged line for sure and not a bad fuel pump, if it's not cold enough out to freeze any water that was possibly in the line then you can try blowing out the line with an air compressor, if you suspect a frozen line use a small funnel and pour a little beat of heat (fuel treatment) stuff down the line and let it sit for an hour or two then blow it out with an aircompressor.... when the fuel pump kicks on it will run until the line is pressurized, if you've got the line off it's just going to keep pumping until you turn the key off.... the other fuel filter (as long as it's installed properly) should be fine...

well this blows... all 5 batterys i took in to see if any of them could even hold a charge....all but oneare bad... and apparently i broke the only good one.... so this maybe comin sense to everone else... but to thoughs who dont know.....be careful with you car's battery( side post batterys ) if you tighten them down too much you will snap the inner connection with the wired bolt peice.... so make sure it's not lose but do not tighten it too much.... or you'll have to buy another new battery like me... will be on often to check my other questions but will up date you on the car wen i get paid and get a NEW battery

ok i think i found the relay for it but im ot sure if it's bad.... i used a ohm reader to check the current in itand everycomponation was bad(on the 3 progs) i only got an unpowered connection on the open ground in the middle and left prong....

is this the right relay? if so was it tested correctly to see if it's bad??
