truck wont start
We have changed the fuel pump,checked the batteries,tested with ohms meter,cleaned battery posts,checked to make sure security system wasnt on and this truck still wont crank. Help!
I'm assuming seance u changed the fuel pump the tuck is cranking but won't start? If that is the case then crack open 1 of the fuel lines on top of the intake manifold. BE CAREFUL! THOSE FUEL LINES ARE UNDER EXTREME PRESSURE! If fuel comes out when u crank it it's most likely injectors and connector tubes. Pull the dip stick to make sure there isn't fuel in the oil. That would all so indicate bad injectors and tubes. Make sure u have a good fuel and air filter before all of this. If no fuel is present from the cracked line and u have a good fuel filter it's most likely the injection pump. That's assuming the pump u changed was the lift pump in the tank. If the truck won't "crank" and assuming the batteries where tested correctly. Also assuming things like the radio and lights still work u should check wiring for damage. If no damage is present check fuses. If fuses r ok make sure u have power to the starter from both the power and ignition wire. Make sure grounds r tight as well. If u r getting power to the starter it is most likely the starter motor. If there is no power to the the starter it could be a million other things. If that is the case reply back and we'll go from their.
mine is doin the same thing. wont turn over. we can make it crank through the starter solenoid relay but it wont start so the computer isnt letting the truck start!!!! got juice every where dosent need jumped and its not the fuel pump or a spark plug cause it wont attempt to crank. Try resetting the computer by unhooking the battery and leaving the ignition in run position for half an hour.
