Do i have oil pump problems? 96 GTX

[jimini cricket]

I rebuild the carbs, changed the fuel lines, changed the oil filter, cleaned the fuel and oil tank, cleaned the fuel water separator filter, cleaned the fuel selector, and put it all back together. Filled the oil tank and the fuel tank.

When i cranked the engine i did not see oil being sucked into the carbs at all, even though the engine was not starting because i forgot to turn the fuel selector to on.:facepalm:

When i was installing the oil pump cable it got pinched between the round lever and some small protrusion and i had to wiggled it and in the process i turned that round lever a few times in both directions. Did i screwed up the oil pump? It was running fine before.

Is this normal? Not to see the oil being sucked up to the carbs if it doesn't start?

Is oil supposed to be sucked into the carbs even if the fuel selector is off and the engine is not starting and just being cranked?
Please help! Thanks...

It moves very very slow at ilde or cranking. Hold the oil pump wide open while cranking and you should see it move.

It's not a bad idea to run premix in the first tank after doing the work that you have done

Didn't think of that (the premix), Thank you and i will. If i just put in it 5 gallons, how much oil should i put in it if it is using the oil pump too?

In addressing your other post, while cranking it i did hold the pump wide open but i didn't see any oil moving up either of the lines. Maybe i screwed up the pump?

It might need to be primed. There is a bleeder screw on the oil pump. Put a rag or something under it, and slightly open it. Crank the engine a bit, until there is some oil leaking out. Tighten to spec, and watch while the engine is running. You can hold the pump wide open as others have said to get her pumping.

There is a spring around the axis of that round lever that is loaded to bring it back to the idle position. By "turning that round lever a few times in both directions" it is possible, even probable, that the spring is either unhooked or no longer working properly. It might be easiest to see how to put it back properly by removing the pump and working where you can see it. I doubt it hurt the pump but may have distorted the spring.

Run the engine at idle while holding the oil pump lever in the WOT position and you should see oil slowly moving through the tubes if your pump is working and your injection ports are not clogged.

Did you bleed it? Unscrew the bleeder screw until oil dribbles out.

Hi! Yes i did, i read it in the manual, i did place a rag and bleeded it. Thanks! But no changes.

Hi! Yes sir i did, but i didn't see any oil running up the lines even when i was holding the pump wide open. Tomorrow i am going to try to start it again, but this time with the fuel selector in the "on" position LMAO!:facepalm: I tried to start it Friday, and the selector was in the off position! lol! I think i broke the blessed oil pump geez! Is it difficult to take out and put back in. :cheers: and thanks!

Hi! I did that and bled the pump, the bottom lines are full with oil and i didn't notice any air bubbles, oil ran into the rag at the oil pump and then i closed it. The carb oil lines are new and the oil is new, Amsoil interceptor. I am going to try again tomorrow if the seadoo Gods allow me, its been raining cows here and storming. It was running fine before but you might be on to something. I just hate to have to take that pump out. Have you ever taken one out? Is it difficult? It looks cramped in there. :cheers:

Wasn't bad, two socket head bolts and it came right out. They aren't the same length so keep track. I didn't need to disconnect any of the oil lines or the cable.

Well, well, started the seadoo and at first it rev up immediately after it started, so i turned off and readjusted all the links in the carbs, readjusted the throttle cable, and the first 5 gallon of gas were premixed with 8 oz. of Amsoil interceptor, but after it started the oil lines to the carbs filled up and the oil pump is working fine, so i went ahead and filled the tank, treated the gas with sta-bil, and ran it.

Also readjusted the throttle speed to 1500 rpm. It started right up, every time i hit the switch, with no smoke. So, i told my wonderful lady, that we were going to the lake to tweak the Doo. At the lake, it started right up, several times, at WOT it hit 51 mph at about 6500-7000 rpm. Then, after running for a while, it wouldn't hit 51 again, so i pulled her over and looked at the engine and since i was tweaking the carbs i had left the air box off and the flame arrester came off, place it back and it hit 51 mph. again with no problem.

However, the high speed screws are turned all the way counter-clockwise so it is probably running rich?
But overall it ran like a champ! :hurray: and never had any troubles during the several hours at the lake.

I am going to look at the spark plugs and see how they look tomorrow if i have the time.

Thank you to all of you who helped me! :cheers:

Awesome! Yea man, leaving that airbox/flame arrestor off or using an aftermarket one without making the proper adjustments will definitely make you think there's some carb related issues going on.. Glad it worked out for you!

Thanks! I was surprised that it started once the fuel selector was in the on position, i was expecting sputtering and all kinds of problems adjusting the carbs, but, it started right up and ran really good.

Thanks to this forum i have learned a lot, thanks to all! and thanks for your reply :cheers:
