My 1st pool- pump issue

Just bought a foreclosure with a badly neglected in-ground fiberglass pool.

Step one was repairing the break on side that has started to fold in. I used multiple layers of fiberglass resin and cloth. Seems good so far. Filled it water from a hose and filled in gap between sides and coping with sand.

Step two. Pump motor just "buzzed" and wouldn't turn. Replaced the capacitor and pump motor seems to run fine now.

Which brings me to my third issue. I have no suction. Coming off pump on suction side there is a T one is capped off and other side goes to the diverter which in turn T's one to vac port and one to skimmer/main drain. I set "off" to pump side and cut cap off, ran 1-1/2 hose directly to the pool. It will pull in for about 5 secs but once hose has water in it vacumm peters out. Do the turbines wear out? Any suggestions what to check?

Welcome to the forum. Couldn't quite follow the suction path in detail, but are you saying that you basically have a single hose feeding the pump and it primes, starts pumping, then quits? Usually once a pump gets going it won't quit pumping. Impellers generally don't wear out. When you say 'once the hose has water in it the vacuum peters out' do you mean the pump basket gets air in it? If so, here's what I'm thinking. If you hooked the hose to one side of a Tee for example, put the end of the hose in the pool, started the pump, it would prime but once you started pulling water maybe the 'other' side of the Tee, the one without the hose, has now exposed an air leak once water was sucked out and that's what's causing the flow to quit.
Glad the pump fix was an easy and cheap one.

not 100% sure what I did or how but I got it pumping. Best quess was it just wasn't priming and had air pockets which reduced suction. Now to just get water to clear up, but that's another section of the forum
