Check your oil. Your oil light is on. The engine light is a generic "check engine" light, so I can't tell you about that one. It may be just because your oil pressure light is on. Easiest way to find out without spending too much scratch is to get an ODBII scanner and look at the codes. Something like this:

First, oil. If that doesn't clear it, scan it.
To add on to this, a cheap and good investment is a basic OBD II reader (eg. https://www.amazon.com/Reader-Diagnostic-Check-Engine-Light/dp/B004IV58AY). They are especially useful when the catchall "check engine" light comes on. There should be a port underneath your steering wheel somewhere (it's often easier to see if you sit on the ground with the door open). Plug the reader in, turn the car on, and it will give you the error codes that you can google along with your Make/Model to figure out what's wrong.
If it's something simple then you can easily fix it and even if you take it to a mechanic, you can lead in with "this is broken" and catch them if they try to charge you for hundreds in diagnostics and unnecessary parts.
Also I don't know what area you are in but frequently Auto parts shops such as Auto Zone or Advanced Auto Parts can be a wealth of knowledge; they'll make sure parts you're buying are a match for your car and sometimes will even loan you obscure tools you may need to complete a job.
Why would you bother when a cheap OBD-II scanner costs $16?
(Let's be honest; if you need something beyond the cheap scanner then your problem is more than likely not something you're going to fix in your driveway unless you're a mechanic anyway!)
Funny thing is it's usually not the engine. Most of the time I've seen it come on, it's an exhaust problem. It can also be something like a cylinder misfire in the engine but you'd probably notice that before the light came on because it would be running really rough.
Anyway, you can just buy one of these and read if your OBD is throwing any codes. I don't know if this specific one is any good... just the first one that popped on Google. Or you can take it to Autozone and they'll check it for free.

The one my friend has, and the one I'm going to ask him to read my car with tonight is this: http://www.amazon.com/Reader-Diagnostic-Check-Engine-Light/dp/B004IV58AY
If it works out, I'm ordering one immediately.
Might be the onboard computer or other electronics then if you think the Fuel Pump is fine. There are electronics in the Relay, though, and it could just be an error with the starting sequence. Do you have one of these by any chance? Might narrow down the issue, might do nothing, might outright tell you what's wrong. Also just good to have on hand, that way if you ever go to a mechanic you can inform him ahead of time that you did an OBDII reading, and tell him the diagnostics it gave. Much less likely to get gouged by expensive tests like engine compression if you come armed.
I'd wager to say that the Tesla allows for more control and more configuration, so perhaps i should have said "a customizable on-board computer".
Since the majority of cars today get their "sophisticated" computer translated by a specific piece of hardware that gives feedback in cryptic codes that require translation.
What year?
If you are just trying to read or clear codes, This will work. It's cheap and it gives you the code. I have this exact one in my tool box and bring it with me if someone asks me to look at their car. I then use google to search what the code means for the car.
You might want to buy one of these.

It allows you to view and reset the code yourself. If you keep an eye out they go on sale for $10-$15 sometimes too.
