i had a code 43 once it was a frozen fuel system relay, a lot of people have had to replace them, its not a very expensive part , if its fuel i would add a little of the original Heat once in awhile and maybe some SeaFoam, hope it helps

Ethanol additive is not helping!! I try to run couple ounces of SEAFOAM at every fillup.

as far as i know, we dont have e10 fuel, guess i could try iso heat claims that works with efi, last night an attack apex couldnt start because of same problems with frozen efi (no fault code) for about 30 mins or so finally started, possibly water in tank thats screwing around with efi?

ethanol helps with water similar to isopropyl. Around here since we switched to 10% ethanol, the fuel systems in cars are not freezing up like they used too.

Has nothing to do with the fuel its just the relay. Its the third one from the front of the sled in the row of 4 at the nose of the sled. See it alot regardless of fuels being ran.
