Extended cranking time

Hey guys

Ive noticed it seems to be a common issue on 1grfe motors.

Motor turns over fast but takes 6 cranks to finally fire up

During my reading i have found that toyota dont use a "fuel priming setup" where the pump primes when ignition is turned on.

They are rumoured to use a one way check valve to hold pressure to the rail while the motor is off.

Im not sure whether to install a check valve to fix the long crabk issue or new fuel pump. Has anyone successfully adressed thia issue?

Hammertime, did you manage to resolve your issue?

Yep sounds familiar. Tried getting the spark plugs changed in hope to get her firing up better, however the plugs that came out were reasonably clean, so as others have stated I'm starting to think it could be a fuel preasure issue.
