hi guys i need a little help here,my early 04 standard,has been giving me some isuues lately,it first started almost a year ago but was very intermitent so i didnt do much about it,been doing it alot more lately and let me stranded yeaterday,when it forst started i thought it was the clutch swith as it seemed to start after i pushed the clutch in hard a few times,it doesnt crank at all,so i bypasses the switch and it coincidently didnt do it for awile but came back after,then i removed the predator and it coincidently went away,none of those must be the prob as its back,i also have the skim key code but the pred always made the code,so i dont think thats the prob,it seems if i turn the key on and off many times it finally goes,the last few times i had to turn the key about 150 times to finaly get it to go,i had my kids in the truk and i had to walk home with them yeaterday,i walked back bymyself and turned the key about 100 times and it finaly went,iam scared to drive it,what should i chek,could it be somehting in the ignition or in the wiring somewhere,its intermitent so i think it would be hard to detect at the dealer,it doesnt have any codes so im not sure what they would look for,anythought guys,please give me any info u mite have on the matter,thanx in advance
