Looks like you'll have to pull the pump and check. There's a hose that connects the fuel pump to an internal fuel filter. Could be that has gotten brittle and broken.

From the SIP, it looks like that hoes is sold as part of the fuel pump housing (item 15). Am i reading this correctly?

OK...I disconnected outside tank hook-up and turned switch on and fuel pump shot gas out of tank. I then proceeded to clean both relays and fuses and even tried swapping relays and still don't start. I have good spark and I am sure its fuel related...is there a fuel regulator somewhere that could be bad? Started fine a few weeks ago...just seems its not getting fuel.....thx for anyone's suggestions.

I suggest buying a manual, could be a fuel filter problem or regulator or etc...

If fuel shot out of the tank bung with the hose disconnected the check valve isn't functioning, maybe stuck open or bad orings. The check valve is the part the hose plugs into under the tank.
There's a pressure regulator in the fuel filter housing inside the tank. Also if you find a bad hose inside the tank avoid replacing with standard rubber fuel hose, won't last and won't contain pump pressure.

It only shot out bung hole when I turned the prime switch on....then stopped...so that makes me think that it is not the check valve?...I don't have a fuel pressure tester to check it.

OK so it wasn't a continuous stream of fuel squirting ? It shouldn't do that either, should just be a dribble, enough to dampen your hand is all. But it sounds like your fuel system is working up to that point.

Try unplugging the maxi-fuse for a minute to reset the electrical system. Then try starting as usual. Let us know what happens ... Then check for stored codes afterwards if there are any.

Pulled fuse and cleaned...it checked out ok...still nothing. I don't have any scanner to check for codes....the security system wouldn't be affecting it would it? I thought it wouldn't even turn over if it was that. I put new batteries
