Hello and thank you for your question,The code Code 85 is for the canister purge solenoid and this indacates a problem with the solenoid or the circuit to it and should not cause a not start concern. The code 10 is a separator code and normal to set during a scan. Code 95, in keep alive memory (KAM) of the self-test are related to the fuel pump circuit. The powertrain control module (PCM) monitors the output of the fuel pump relay when the relay is energized. For this code to be valid, the car would have to exhibit a symptom relative to low or dropping fuel pressure or an intermittent connection problem causing a momentary loss of voltage to the PCM from the relay. These service codes will not cause the PCM to turn on the malfunction indicator light. If no fuel pressure related symptoms are present, the circuit between the PCM and the fuel pump relay could cause the codes to set. It is also possible that simply hitting a bump hard enough to cause the points to bounce in the relay without creating a driveability concern can set these codes. What type of problem are you having?
The fuel pump relay should have key on power on the red/black wire as well as the orange light/blue wire. Do you have key on power there and if so are you getting key on engine cranking power out of the relay on the Pink/black wire?
Okay the fuel pump relay is controlled by the ground switching signal from the PCM (computer) if you ground the tan/green wire at the relay with the key on will the pump run?
Okay the tan/green wire is the ground switching signal from the PCM and if the pump only runs with your supplied ground that in most cases mean you PCM has failed.
There is no way to test it with out replacing it with a known good unit or removing is and sending it out to a repair facility that build PCMs.
Okay Im here if needed. Let me know.
You can check for injector pulse with a standard 12 volt test light by placing the test end on the power side of the connector on any one of the injectors and the ground end on the other wire and crank the engine over. If you have pulse the light should flash.
