I've checked the Coolant sensor resistance, it is ok.I can not find any access valve in the fuel rail to connect fuel pressure gauge, so I really don't know how to get the fuel pressure. My old PCM was confirmed bad, 5v ref voltage is not constant on some sensors plus it can not start the engine, it only cranks. My question is, can I bypass the fuel relay control side and start the engine without harm to PCM or other component? My reason for this, is if the engine runs continuous, the problem is within the fuel delivery ie. Fuel filter or pump. If it runs and dies after few seconds, then the problem is not the fuel. Please advise. Thank you for your suggestion Hmac300.
