There could be about a couple thousand things wrong. How cold is it there? You say it ran ok to work, but was it really ok or was it a little rough? How far do you drive to work? Does it get fully warmed up? Highway or stop and go? When was the last time you changed the plugs? So now it has sat there overnight. Get a good set of jumper cables and jump it, and try to start it. Chances are it is flooded. Danny

You should see around 38 with the hose off the regulator. Sounds like a bad fuel pump, plugged fule filter, kinked hose, low voltage at pump, bad fule pump relay, plugged/collapsed sock, defective regulator .............
When you turn the key, can you hear the pump prime and then stop?

No start

Hi,
9 psi won't get it. Unless the filter is blocked, time for a fuel pump. Go with a Walbro340, and put in an adjustable regulator. Sorry for your trouble, and good luck with the fix!

pump runs with key on for 2 sec but only builds 7 to 9lbs of pressure

Hi,
You could try to deadhead the system by blocking the return hose, and it might bring the pressure up. I doubt it,though.Anyway, time for a fuelpump. Easy swap, beats some of the others.

sounds like a weak pump , like the other guy said go with the 340 walbro !

Thanks everyone i will be putting in a new pump in tommorw afternoon will post when done THANKS!

Do make sure you replace the filter. It never hurts to throw in a 340, but the filter could be the main problem. Do they start putting alcohol in the fuel there in November? That will release a bunch of crap from the tank that is stopped by the filter. Later.. Danny
