2002 gtx di will not stay running

[9dakota7]

the seadoo will turn over and actually start for a sec or 2 sometime! why will it not stay running? i have read of ppl changing the rectifier!?!?! is this something i should look into? it had the wrong oil put in but it has all been cleaned out and will not start or will only run for a few seconds. the longer the key is out the better chance of it actually starting!

rectifier controls voltage so it should not shut ski off. check fuel system. what is compression?

sounds like your loosing fuel presure do a test on that should run at 107 psi +/- 2 a good dealer should pin point it straight away
