Im trying to start my prochem bruin and when i turn key sometimes it will try and start and sometimes its just dead. I replaced battery what else can this be? Some sort of sensor?I also want to add that i cleaned and redone wiring by starter. Wondering what can make it turn over 1 minute and nothing the next.

Maybe your switch is bad...are you getting power to starter when it doesn't turn over?

I understand but if it doesn't turn over at all maybe starter not getting power at all sometimes. This things vibrate a lot and older wiring becomes brittle. Have someone try and start it and you testing for power a few times.

Check your grounds and connections. Also your float switches will act as a kill switch.

If the starter isn't even engaging, it is going to be the key switch, the starter solenoid, the starter, the battery, the ground, or wiring to any of the above. Sensors do prevent it from starting, but there aren't any sensors that prevent the starter from turning.

Starter solenoid could be bad. Get someone to jump or bypass the solenoid.

Ok it is turning over now and will not stay going now. Cleaned the carb, the spark plugs ECT. It stays running if I spray a little ether in it but the thing does as soon as i quit speaking it. There's gas in the gas filter boul. It seems it's not going any further then that though

You might need to adjust carb and check fuel pump, lines and filter...something might be clogged...even if pump sounds like its working maybe its not working right.

Check lines and carb and new filter. How many gpm's is this pump suppose to get. The fuel goes all the way up to bottom of carb and that's it. Do you think it still needs a new pump. Do you think it could be some kink of sensor? I'm sorry I'm a woman trying to understand all of this.

Not enough information to troubleshoot with out throwing darts at a possible cause. Because Bruin is in the name of the TM and knowing how long since it was produced, 10:1 sez you have a wire somewhere with worn through insulation grounding out giving you fits...

gpm of the pump I don't know but it should be low pressure pump...around 2 psi. I think you mean it goes to the bottom of filter...thats normal to see it pool up there...you can alway take fuel line off from carb...turn key and switch and pour fuel into a container and see if it keeps flowing steady. In an open area...no flames around. careful.

start up sequence on bruin should be similar to my prochem so I assume you hold override switch as you start it....is it turning off when you let go of override? or does it stay on and then shuts off at random time?

Good...on these older machines I've found that most of the time whoever had them before never cleaned anything and sold them because they didn't work... supposedly

Ok now I went to start and it's winding out. What size battery do you use. Could cranking amps be to low? I bought brand new it's only 225 cold cranking amps
