    496mag no start issue.

    I think so, I found quite a bit of paint chips, which corresponds with the cool fuel paint issue. Current update: Cleaned all injectors in my ultrasonic jewelry cleaner 30 min bath followed by a second in clean fuel injector cleaner. Then cleaned inside to confirm flow with fuel injector pulse/...

    496mag no start issue.

    That's what came out of my fuel rail... if that's not the problem. It definitely needs to be cleaned and fuel injectors. I'm stunned!

    I'm starting on the rail now. I swapped cam sensors again to confirm. No change, starts fine on the good port motor.

I've changed the crank sensor on the port motor years ago and it was a bear! Really hoping it's not that. Is there a way to test it. I assumed that seeing rpm confirms it...

Rebuilt cool fuel with new filters and Walbro pumps (low & hi). New box and a new top (pump cover with regulator) sent to me by mercury...

    496mag no start issue.

    So I bled the fuel rail and hooked the cool fuel up to a external tank and it will still only run for 2-3 seconds. I disconnected the hose from the regulator and I got about 6-8 seconds but it ran like crap. This points me at the cool fuel box. I had rebuilt the CF3 last year and it ran great...

    496mag no start issue.

    So it took a month to get a Sierra MAP sensor, the Merc ones are still on back order. I replaced the battery after my battery tester showed 52%. (I had 13v but only 1/2 the CCA). It will start on starter fluid but won't continue to run on starting fuel. I confirmed fuel injector pulse with a...
