I have a gs300 and I can’t get it to start I changed my filters got a new maf and a new battery still won’t start still just keeps trying but never cranks it almost did then stopped can some one help me plz

 

Cranks means the engine turning over.

Are you saying your engine does dot turn over?

Giving more detail of your issue, how it started, and what you have done so far will help in us figuring out how to help you.

 

umm it was struggling running the other day and kept stalling out now it doesn’t crank it just keep trying but dosnt turn over it did tho just a few hours ago but just kept reving up high so I turned it back off now it doesn’t crank again I put in a new batter a new maf senser changed my air filter and fuel filter I haven’t done my spark plugs and wires or my coil yet Or Distributer those are my next task I also haven’t checked my fuel pump yet I wish I knew how to explain this better

 

Got it to crank but won’t idle have to keep reved but my Exhaust pipe was getting red hot and smoking what does that mean

 

Valve cover gaskets leaking excessive oil into the spark plugs/exhaust manifold? Pull some plugs off, are all of the holes clean? Sounds like your misfiring on multiple cylinders.

 

Well there was oil around my spark plugs I haven’t finished pulling off my intake Manifold to get to the rest of the spark plugs would this be the only reason I am miss firing or would there be more to it then that

 

Watch out for the coolant line connected to the throttle body going across the valve covers, it can cause a big mess right in your spark plug galley when you try to pull it off. Yes, this can definitely be a large reason why you're mis-firing; you could also need new spark plugs/wires/cap&rotor. One of my spark plug boots completely ripped when I tried pulling it off, and I also had the same issue with the valve cover gaskets leaking. Make sure to replace the valve cover washers along with the gaskets to get the proper seal.

 

My mass airflow sensor was bad with same issues. You would have a find a used one on eBay or junkyard perhaps. It makes the engine run real rough and won’t start and throws everything off until replaced. Two screws and one connection right on top of the engine.
