Crank no start

I have ran through just about everything I have seen online and its mentally exhausting me. I took the plug out and had a friend crank it and it had a white cloud and little flame come out from the plug hole and its giving me a oil pressure sensor/low code. All fuses and relays are fine. Haven't replaced anything either. I'm just baffled on why it wont fire. Makes a tiny pop noise occasionally. If I let it sit and try to crank the lightning bolt light comes on too for a minute when the key is on. The fuel pump does kick in and sounds fine. So anyone have some ideas what to do next?

Hi,

The lightning symbol usually relates to a problem with the throttle body. Have you had the computer scanned?

Here is a video that shows how it's done. If you haven't, see if you can get your hands on a scan tool and check for codes. Often times, a parts store will lend one to you.

I want you to try one more thing. First, if you are getting fuel and there is spark to the plugs, it should run. Do this. See if it starts for a couple seconds using starting fluid. If it does and then stalls, we know it's fuel related. If it doesn't we likely have an ignition problem. We need to narrow that down.

You mentioned that there was a white puff of smoke. Where did that come from?

Let me know what you find and if there were any issues prior to this one.

Take care and God Bless,
