Compression should additionally be a non-issue unless you overheated the motor as well as blew a head gasket. This leaves us with fuel as a likely culprit. The fuel system has lots of parts including the fuel pump, fuel injectors, gas filter, fuel lines, and also circuitry. Instead of rushing into a gas pump substitute, make certain every other part of the system is functioning appropriately. This will certainly help you prevent a costly, time consuming, as well as unnecessary fixing.
The most effective method to begin a system diagnosis is by doing a gas stress examination. If the pressure is excellent then we understand the fuel pump is excellent as well as whatever leading up to the fuel rail, hence assisting us identify the problem.

The gas filter side will constantly be the feed side. Go on as well as plug in your fuel stress tester with the accessories that featured it and tighten whatever down securely.
3. Plug in the fuel pump relay.
4. Try starting the lorry. Take a look at the stress analysis on the gas stress gauge
Exists no stress? Try switching the fuel pump relay with one more one similar to it (i.e.: A/C relay).
Is the pressure reduced? This could be a stopped up fuel filter. Go on and also replace it due to the fact that this can quite possibly be the culprit, and if it is, you have conserved yourself numerous dollars if you believed it was the gas pump.
