Guys... And Gals...1999 225 Optimax
Had my motor running last weekend on muffs in the yard a few times when I was doing compression checks. All I did was install my JP and now it will not start!! I never touched the motor's wiring or any controls. It turns over and once in awhile it will spit like it wants to fire.. I am hoping to check for spark tomorrow and it sounds like the injectors are working and fuel pump was also..
Anything else I should check?
