What are the symptoms of a bad water pump?

1. Coolant leak at the front-center of your car. The water pump is comprised of multiple gaskets and seals that keep coolant contained and ensure that consistent flow of coolant is delivered from the radiator to the engine. Eventually, these gaskets and seals will wear out, dry up, crack or break entirely.

What happens to the engine when a water pump fails?

3. Engine is overheating. When the water pump fails completely, it will not be able to circulate coolant through the engine block. This results in an overheating situation and if not repaired or replaced quickly, can cause additional engine damage like cracked cylinder heads, pushed head gaskets, or burnt pistons.

What should I do if my water pump is not working?

As discussed above, an engine will maintain a consistent temperature when the water pump works correctly and circulates water to a functioning radiator. If you notice steam coming from the front of your motor, you should pull over to a safe area and contact a mechanic as soon as possible.

Why is the fuel pressure bleed down test not working?

The fuel pressure bleed down test would be verifying that the fuel pump and spider injection fuel pressure are good with no problems. There is gas up to the Schrader Valve so there has to fuel to the injectors. The only other thing it could be is there is no injector pulse to make the fuel injectors open and close.
