Sooo check engine light is on
Yesterday morning i was driving my wifes H2 and the check fuel cap signal came on, so when i got to my destination i opened and closed it and the light went away, but this morning i was driving it again and it came back on and i know for a fact the cap is on securely, so i ignored it and then later today the check engine light came on, what do you guys suggest

do you have access to a programmer that can read the codes? if you can get the code off the truck and post it, i can tell you what it's for. other than that, i would try the fuel cap again. check to see if there's a buildup on the threads of the filler tube that may be causing it to not seat properly.

No sorry I dont have a programmer although now i wish i did, but the check gas cap text is gone and it has turned into a check engine light, when i checked the gas cap the first time i whipped it all down

it's still worth a try reseating the cap. i'm not sure how many you need to go through, but the truck will reset the light on a certain number of ignition cycles where the error isn't present, it typically doesn't shut off on the first try. other than that, if you have any mechanic friends, or are on good terms with the local service department, they may be able to read the code for you. the benfit of the programmer is that you can also clear the codes (you have to in order to proceed on any of the programming).

there are multiple codes that will make the check engine light come on, and while there are a lot in connection to the emission system, it could be any number of other issues. however, since you got the "gas cap" indicator that's most likely at least part of the cause. the majority of the error codes will reset after 3 ignition cycles where the diagnostic check comes back clean. it may be as simple as starting the engine a few times to clear it. let us know how things turn out.
