We just bought a 99 accent with 39k miles on it for $1000. Seems like it could really be a great deal. It runs like poop. Problem is there is a check engine light on... Hardly has any power at all. Figured it would be a good project relatively easy fix. Took it to autozone and it came up with 5 codes. One odd thing is it says Nissan/Mazda or something like that instead of Hyundai. Anyways, the codes...

1. 300 Multiple Misfires
2. 301 Misfire Cyl 1
3. 302 Misfire Cyl 2
4. 442 Small EVAP leak
5. 445 Large (gross) EVAP leak

I changed the fuel cap. Didn't help. Taking a closer look I see some black grime/fluid smells like gas by what I think is the fuel pressure regulator (1) and a lot of cracking in a hose (2) that comes off the right side of the fuel rail I have a picture I am going to try to post and hope that someone can verify:

1. The part is what I think it is.
2. If they can cause any/all of the listed codes.
3. How to disconnect/remove both of these things. I cannot get them off. Maybe they are vacuum sealed or something.
4. What the cracked hose is/does.

Thanks in advance for any help.

P0300, P0301 and P0302 basically go together. A misfire in teh first 2 cylinders. My advice, replace the all 4 plugs and wires. You might want to consider replacing the 2 coils as well.

The other codes you have wrong (for a Hyundai). They should be:
P0442 Main catalyst efficiency, below threshold (Looks like it's time for a new cat. Get it checked.)
P0445 Purge control valve circuit shorted

1 appears to be the fuel pressure regulator
2 appears to be the main fuel line. Does it come from a cylinder that looks like this?

That's the fuel filter and the line from that to the fuel rail is the main fuel line. If there are cracks in in, get it changed ASAP.

 

Thank you for the reply.

Yes, that is the cylinder that it comes from. It is the 2nd connection from the top. Is there a trick to disconnecting this fuel line to replace it. I cannot for the life of me figure out how to disconnect it. EDIT I was just looking on hmaservice and it seems I have to remove the i bolt on the top. Does that sound right?

That cat. problem sounds really expensive.

Thanks again. I will look into plugs/wires and coils as well.

 

Yes, I believe it's a banjo fitting.
