Muffs are not the best method. You will be better off with a trash can. Have you checked the pee hose it’s self? If not run a piece of wire or weed wacker line through it. They can get clogged.
Be sure the water level is well above the pump.
What do you mean by you checked the pump and impeller?
Did you remove the impeller? Did the fins straighten out somewhat or did they stay curled around? It can look new and fine but it should be soft and flexible to work properly.
Just a thought.
Try pushing it several times and you may find it’s ok. If that doesn’t work the bulb that you push can dry out and have very fine cracks in it and may need replaced. Or there is a fuel delivery issue as mentioned check to see if fuel is reaching the primer.
Two thumbs up to you Crosbyman!!
Your full of great info.
I love this form and it restores my faith in humanity to see people helping out.
I have very little knowledge of the ficht and E TEC technology and this is always an interesting read for me.
Thanks for all you do to help others.

I had a friend told the same exact thing about his compression numbers just the other day.
The shop was also have a big sale on last years models. What a coincidence!!
I ran a compression test for him and all was well.
You just never know who you can trust.
Agreed with taking a break. Sometimes you just need to walk away for bit then light bulbs comes on and you realized what you have over looked.
Best of luck.
I have no personal experience with this but I have seen the screw clamps used on the cmc unit as they were intended along with bolts added to the lower holes in the transom bracket.
I use a brake bleeder/ vacuum gauge and check with both pressure and vacuum. It is possible for a seal to leak in one direction and not the other. Im happy with 10 psi. And I agreed with Racer on the using a compressor. It only take a split second to blow the seal.
Agreed
Anything with a gauge on it from harbor freight is suspect in my eyes. I admit I have a few HB tools but wouldn’t trust anything that needs to be accurate to be accurate.
