OMC Primer Solenoid Question

It's on a 85 omc sea drive 1.6 liter. I had the issue of crank no start in an earlier thread. I have spark and fuel getting through the vro to the carbs/solenoid. When the motor sits for a bit it won't start back up. It just cranks and won't fire over.

BUT, if i open the red lever on the primer solenoid, it will start after a few tries. Then I can close the lever and it will run fine. This is a "push to choke" set up, but when i push the key in i get no click (I think i'm supposed to hear a click to let me know that solenoid is activating).

I assume pushing in the key activates the primer and delivers fuel, but since it's not working electronically, when I open the lever it allows fuel to flow through acting as a "manual" primer. Does any of this seem close to right?
 
your right in thats how it pretty much works. best way to test is get a test light and see if the purple wire with white stripe is getting power when you push in the key. IF its getting power check the ground comming of the solenoid and if it isnt you might want to check the key switch.
 
I'll grab the testlight and someone to push in the key and give it a shot tomorrow. I'm pretty sure it used to click when i pushed the key. Either a connection has gone bad or it's dead..

So let's say I can confirm that I have power going in and a good ground and determine the solenoid is dead. Would that cause the motor to just crank and not fire over at all after sitting for a while (hour or so)?

I guess it would make sense, I don't think they would put that part there unless it was essential to the motor starting cold. Just seems like it loses it's prime fast...
 
thats hard to say, some engines need a little fuel to crank after sitting awhile. then some crank up everytime. that solenoid though is clutch when trying to get a johnrude started.

Click to expand...

You are absolute correct it click and squirt fuel directly in to the carbs directly behind it.
If no click you simpley need to test the purple wire going to it for 12v when you push to start if voltage is present then is a bad primer solenoid check the ground wire also for proper ground (black)
