1997 5.7L Merc EFI turns over but no spark. HELP!

[elvaktran]

Hi, I have a Bayliner Ciera 2455 with a 1997 5.7L EFI and I have one kind of a problem here with the engine, couple of weeks ago it started no problems at all, then yesterday I was getting ready to go to the lake and when I put the muffles and try to start the engine it turns over but does not start. So there I started TS with my limited knowledge....and here's what I got....

Engine turns over.
NO attempt to start at all.
checked 12 volts to the IGN COIL good.
NO spark out of the Coil while cranking.
attemped to crank it playing with the shift stick(just in case the "cut out switch" is bad)... nothing happened.
Open Distributor cap and cleaned some corrosion on the rotor cap and a little bit on the pick up coil...nothing.
checked ECM plugs for faulty connections....nothing.

I know there's a lot to TS but to tell you the truth that's a brand spanking new engine that I haven't put on the water yet, and IT started good a couple of weeks ago... I guess it got to be something fairly easy but getting with the problem IS a problem and I'm kind out of bullets on this one...

I will really appreciate the help, thanks in advance!

Will

In you previous thread you indicated that this was a salt water engine which sat for over a year and you took it on as a project. Also you had it out and water was spraying everywhere. Did you replace the engine with a new one? Have you run through the TB5 troubleshooting sequence yet?

No, I haven't but I will right now and let you know, and about the engine I took the engine out and did a complete overhaul on it from ground up. Where I can get that TS chart? I tried to find it before and couldn't get to it... Thanks
