it ran great afew months ago,cranks but no start.. ive checked fuses,did the wires n plugs,oil reg changed.. new battery.. it wont fire over now?? i bum started it and ran but sounded like it wasnt

Make sure battery is fully charged and spray some quick start in the throttle body and see if it starts for a bit, if it does, it's fuel related issue. Check fuel pressure. If it doesn't, check for spark at the spark plugs

hey irodri99.. yeah ive replaced battery,plugs,wires,air/oil filters,changed oil:( UNFORTUNATELY i was tolit could be my distributor(just bc i does crank over but doesnt give it that extra boost to kick over) so im going to see if my main relay might be gone,if its not that im thinking the starter possibly perhaps?? it happened bc when i changed the exhaust /mainfold to a bigger size(for racing) it cant keep up to the upgrades(the old computer in it lol) BUUTT that being said I did however bum start it last night an it ran(but sounds like its only running on 3 instaed of 4 cyls :( once it runs frbum starting it im able to still drive it,then it dies out because of this unkown problem!! LMAO:P I AM ALSO SMELLING LOTS OF FUEL (more then normal) so ill changed the main relay + the D cap,and also the fuel filter then go from there i guess?? :P BUT THANK YOU FOR YOUR HELP I TRULY APPRECIATE THIS ALOT!! :D
