First my car was running fine i work a 12 hour shift 6pm-6am well... 6pm i went to work it cranked up fine started up drove to work. 6am time to get off i notice that my gas was low so i cranked it up it turned and it turned and im like DAm must have no gas .. i got gas in it filled it up half way .. start the car it turned over and turned over Im like WTF. so it dont work.... towed my car home i checked if i had a spark by checkin i took one spark plug out atttach to the sparkplug wire and place it on the chassis to se if it sparks when i crank. Still nothin no spark.. i go get a brand new distributor replaced it did the same method.. still no spark.. i notice also my main fuel relay wont clic when i have it on the on mode.. my chec engine also wont go off after a few second .. now i go get a new main fuel relay replaced it... the same problem that i been having is still the same.. to recap i have a new distributor got new spark plugs.. and wire.. baught a new fuel main relay.. So those i replaced Still no sparks.... Now what i think is THe ECU.. Waht do you think about that solution do u think it would solve my problem so it will Start up . and get spark. Need everyone help advice opinion on this i need the car to run.. THANKS.
