Hello, my name is***** will assist you.
In order to properly locate the issue with the engine, it is going to take several tests. You are going to need a spark tester and a pressure gauge that can read over 120 PSI.
The first place that you are going to need to test is the test valve on the rear of the VST. Hook up the gauge, then turn the engine key to ON. Watch the gauige and note the pressure. It needs toi read 25 PSI when the pump is running. If it does not, that pump is locked up, and will need to possibly need to be freed or even replaced. Let me know what you get on that.
