1996 Prostar 205 (Original X-star) cranks but wont start
 
Please help me figure this out. Our Prostar 205 with fuel injection died this morning, ran great yesterday then cranks but won't start today. Has no spark or fuel coming out of injectors. All breakers are good and safety switch also appears to be good.

Boat as 3100 hours and about 500 on the rebuilt engine but has been running great.

Do I start with voltage out of the ignition switch or ?

Thanks for the help.

I think I would check for voltage at ECM for injector drivers and voltage at injectors, fairly common for ecm injector drivers to fail on tbi motors.

Thanks, I will check tomorrow but I also have no sparkat plugs. My lanyard safety is working right, there must be some other ground or low voltage out of ignition switch that is causing both the fuel and ignition system to shut down.

Any ideas

Check the MEFI system relay, it controls both fuel and ignition systems.

I have power to the EFI/Ignition fuse. Any thing else to check on the relay?

I tried pulling the connectors to both the MAP and TP sensors and still no joy.

I am about to swap out the distributor. Any other ideas?

Thanks

The distributor was the problem, a replacement solved the problem. Thanks for the help.
