Hello,

Can you share little more details of the issue that you are facing?
Does it start at all? Does it start for a few seconds then stalls?

Typically an engine wont start for either no fuel or no spark, or it could be a sensor that is triggering the issue.

Have you checked to see if you are getting fuel? What about spark to the plugs?

Is your check engine light on?

I will be more than happy to assist.

Thank you.

It starts but a couple of seconds later it shuts off. It's like it won't stay idled. Code p0191 and p0197 pop up when I hook it up to the obd meter and yes, it's getting gas to it.

P0191: Fuel Rail Pressure (FRP) Sensor Circuit Performance.
This could be triggered by either high or low fuel pressure, Damaged or faulty sensor or even a vacuum leak.

P0197: Engine oil temperature sensor circuit low input.
This could be triggered for damaged harness, damaged connector, faulty sensor.

If the temperature sensors provides incorrect data, then the engine will shut off. You need to check the sensor to make sure it is good.

I have attached the basic diagnostics for those codes for your reference.

Please let me know if this helps.

Thank you.
