I wonder if the coil is going also, I had spark but it wasnt like on my camaro. My car makes a serious blue arc when I test the coil, the boat doesnt, just a little spark. I have 12 volts at the coil so I know it's not power issue. I wish I had another coil to test it with. If the dist was 180 out then my timing chain wouldnt be on correctly because I put the rotor at the #1 tower while the dots were lined up.

Wannabe,

I have to look at your situation as 2 possible problems, First I would tackle is why it's not firing when you prime the carb manually.

After reading your posts again, you say you have spark but I wonder if your distributor is out 180 degrees. If you prime it and have spark it should atleast try to fire up.

My guess on the fuel is that once the boat fires for a few seconds it will draw fuel and you'll be ok so I personally would not worry about that problem right now. It may stall a few times waiting for gas but prime it again and I think you'll be ok

well if you sucked it and got it up, you shouldnt pull it though after its up. sorry these are your words,

anyways on the fuel push rod you have to find the low side of the cam and grease the rod so it holds up in there

I made sure there was fuel all the way at the end of the filter hose by sucking on it and getting the fuel up. Is it possible to pump the fuel arm by hand and get fuel moving? I was going to try to pull it and see if that works. Im pretty sure I installed the cam right.

Wannabee, Did you put the fuel pump eccentric back on when you put the new timing chain in?
The cam-like thing on the timing chain that moves the pump arm? yep...

no condensor if you converted, good thinking 81, did you remove the fuel pump? alot of times if you do have a bad pump the diaphram will leak gas into the crankcase also, if so be sure to change the oil a couple of times or the gas will wash down the cylinders, thats if gas got in there. concentrate on why you are not getting fuel to the pump. if you were a woman i would say put some gas in it

I actually pulled the fuel line to the carb and there wasnt any fuel coming out while cranking. There isnt a condensor b/c it's electronic correct? Atleast i didnt see one in there when i put the new module in.

Yea i tried moving the distributor a little bit both ways and still nothing. I followed the advice given to me in another thread to get the timing close enough to get the boat started. Put the timing chain dot-to-dot to get TDC #1, then made sure i got the rotor to point at the #1 tower on the dist cap. I also checked the firing order twice and it's correct.

I had spark, electronic ignition, but my starter is really slow even with a jumper on it. I think i need a new starter to get it cranking faster, then see if i can work on that after. I also need to set my timing, but i cant do that until i get the damn thing to start.

Well I finally got a chance to work on my boat to put the new timing set on etc after my problem. Anyways, I went to fire it up today and no go. My boat had been getting harder and harder to start over the past year. Before the timing gear broke it would take me 20 min of fiddling and putting a jumper on it to start. Today I figured the same thing, but after two hours i couldnt get it to start, even poured fuel down the carb and nothing. I searched on here about accelerator pump problems and people taking off the throttle cable to test. When I took the cable off and pushed the throttle by hand I didnt have any fuel coming out, no matter how many times i pumped it. I figured that there was not enough fuel in the lines because it has been sitting for a while, so I cranked it for a while and still nothing. So now im thinking either the accel pump or the fuel pump is not bringing fuel up to the carb. Any suggestions?
