well here goes.. i have a jetta that has had most front end equipment replaced.. what i did recently was plus cap rotor, feul filter, battery,... ok here the prob.. it starts.. but it takes more than once to get it to turn over .. and if i hit the gas while cranking it def will not start... now just after is turns a lil it kicks on... and then there is a lil puff of smoke and it is running a a1 condition... dont know what the prob is.. someone told me to much gas.... so i what i need to know is where you adjust the fuel pump at... under the hood... or if anyone has ideas.. what could cause that prob
