2001 Sea Doo Challenger 240 EFI doesn't idle nor start well

Hi. Started the season, started ok, went out on water, max 2800 RPM and about 10 knots. Took it out, replaced fuel (as much as I could pump out--then added 10 gallons premium and sea foam), plugs, both fuel filters. Now hard to start (I have to turn the wheel). Checked spark with a inline light tester, light up on all 6 (idle). Once started (on land), seems to run fine at higher RPM--ran at 3000 for a minute or two (with water attached). Bring to idle, dies. I took off the lift pump output, fuel pumps out. Not sure if it is enough pressure, but it seemed to flow ok. I did not shoot out very far--couple of inches. Should I put a pressure gauge on the lift pump output to measure? Replacements hard to find. Any thoughts?

Thanks!

Phil
