Compression should likewise be a non-issue unless you overheated the electric motor and blew a head gasket. This leaves us with gas as a likely perpetrator. The fuel system has lots of parts consisting of the gas pump, fuel injectors, gas filter, gas lines, as well as electrical wiring. Instead of hurrying right into a fuel pump replacement, make certain every other part of the system is functioning correctly.
