heres the original post ....

went out to start the truck to head to work. no go! tried again still nothing pushed the pedal down and it fired up but was super gassy smelling and wouldnt stay running on it own. SO I TOOK THE DAY OFF! (to work on the truck) had a couple of times the past few days it studdered at highway speed but came out of it very quick. filled up last night so im pretty sure it didnt freeze. im lost and dont know how to narrow the problem... spark? fuel?

update- got it started and foot fed it for a few minutes 2-3... turned it off was going to limp it into the garage when it got light out and warm it up. went out about 30 minutes later and it fired right up and stayed running. no more foot feeding pulled it into the garage and warming it up now anyway ? maybe some gas froze? if anyone has any ideas what to check id appreciate it ! i dont want to take tomorrow off too!

this was wed. morning this week didnt have a problem again till friday morning same thing. foot fed it till it got up to operating temp turned it off and back on and ran fine all day friday driving around town multiple stops while i was shopping. no problems .

sat morning (this morning) went out to see if it would do it again and it did. havent tried to warm it up just foot fed it to see if it still worked that way

i seafoamed it wed afternoon. still on the same tank of gas 1/4 left. checked for codes yesterday at advanced no codes at all.

oil light came on yesterday when it died once while foot feeding not sure if its relevant or not

anyone have any ideas? dealer will be closed in an hour for parts/stuff but i can get to part stores if i need to still

 

?....what do you mean by "foot fed"? never heard that term.

 

basically when it almost started he pushed on the gas to get it there then kept the RPMS up for a little bit or when it sounded as if it was going to die he just pushed on the gas!

 

yes i had to keep the rpms up over 500 to keep it running 500-1500 sounded like it was missing over 1500 or so it sounded like it was running right. as soon as i let off it dies wont start again without pushing the gas down . almost like its choked or needs choked but its EFI so that doesnt make sense to me!

 

Maybe IAC going bad?

 

anyway to diagnose IAC?

 

thats what i figured, just never heard that one before.....

 

so i disconnected the battery this afternoon. set them down together (unhooked) like ive read to do before on here ... went back out awhile later reconnected everything and it fired right up!

 

told you disconnecting the battery is the magic Reset button! lol your rims could fall off and motor fall out...but you disconnect the battery overnight and it magically puts itself back together! lol

 

Holy S*&% we have some complicated ECU's!
