HI, I have '01 5.7 merc in a 22 searay and have had some fuel problems( i Think) sometimes at cold start, starts and runs great (small stumble) after about 10- 15 min starts to pop and backfire thru TB- if i shut down, hard restart, no power, can coax it up on plane but really hard. SO, i looked at seperator / filter , replaced and dumped it out. NO water. took a long time to see spray out of TB injectors. pulled filter, saw was only 1/2 full of fuel??!!. I cycled key to prime system and finally I saw some spray from injectors and it started but same problem, no power. SOO, i figured fuel pump. BIG deal, nasty job, but..got it done and same thing, great cold, no power 10 min later. I changed the filter again, even though i saw no signs of contamination during pump change. ( on the screens). can injectors work intermittently if bad? could it be oil pressure? (seems to be ok) could it be a bad pickup? could I have 50 gallons of gas/ethonol/water sludge ?(startron no help to date) could I have some electronic problem? could my kill sw/ lanyard be controlled by my ex-wife? AHHHHHH! help! Oh, how about pressure regulator? its part of that nifty, fuel "cooler/ pump $400.00 gem" that isnt included in the rebuild kit. (accidentally on purpose?) ANY help would be appreciated. THANKS
