ok i just replace my front main and then i got my motor ready to start then i turn the key then you her it turn over then it just does load pops and the truck wont fire someone said it could be starter or my timing is off? i anit sure my yotas been a bitch latey getting tierid of it....

 

if it's turning over, it's probably not the starter. My vote goes to valve timing.

 

i talk to a guy that works on toyota all the time he said my timesings off and he going to help me tommrrow to fix it

 

x2, timing would be my 1st guess too.
