Compression must also be a non-issue unless you overheated the electric motor and blew a head gasket. This leaves us with gas as a probable perpetrator.

As opposed to rushing right into a gas pump substitute, make certain every other part of the system is working properly. This will help you prevent a pricey, time consuming, and unnecessary repair work.

The most effective way to start a system diagnosis is by doing a fuel pressure examination. If the stress is excellent then we understand the gas pump is good and whatever leading up to the gas rail, therefore helping us identify the issue.

3. Plug in the fuel pump relay.
4. Try starting the automobile. Check out the pressure reading on the fuel pressure scale

Exists no pressure? Attempt exchanging the gas pump relay with an additional one similar to it (i.e.: A/C relay).
