Does anyone know absolute way to check a FPR?
I heard that if I can smell fuel from the vacuum hose connected to FPR, means bad. However, I want to know if there is another way to check.
I don't want to do any guess and keep changing wrong parts.
I have changed a fuel filter, OVP, plugs and wires due to cold starting issue.
What you need is a vacuum hand pump with a gauge on it. Once you have your pump, hook it up to the fpr by simply connecting it with a small peice of rubber hose (but make sure its tight and doesnt leak) and see if it holds a vacuum. If it doesnt hold a vacuum then its bad.
