Question about 2005 Ford F 350 Super Duty

1 Answer

My F-250 is only cranking at about 1/3 of the normal cranking speed when trying to start the truck. I have used new batteries but it changed nothing. It has the 6.0 turbo deisel. It was running perfect then when I shut it off an went back to start it; nothing.

I have a Diesel 4WD Grand Vitara. Was driving normally and then all of a sudden it would not start. Previously when I tried to start it there was a little whirring noise and then when the light sequence...


you failed to say, does crank, when it don't start?
and btw, the fuel pump on most cars only run cranking or running
some run for 3 seconds, key on, but you'd miss that fact. using
only one person.
the key word here is crank, does it crank as full speed, via the cranking starter motor. that is the engine cranks spins fast.
on this car it will spin min 250 RPM, cranking, and uses large
battery current , so on diesels it takes a very strong battery to start
and working glow plugs.

Car wont start in the cold


STARTING PROBLEM WHEN ENGINE IS COLD.
- Check specific gravity of the battery and perform battery test.
- Check starter motor cranking speed. (required speed 250 rpm)
- Check alternator performance and health.
- Check engine oil viscosity. (recommended synthetic 5W20)
- Check cylinder compression. (COLD 190 psi or more)

Cutlass ciera wont start


Does the starter spin the motor at normal cranking speed? If there seems too much friction, try turning the engine over by hand to check if the engine turns freely. Put a socket and wrench on the center crankshaft pulley bolt and turn clockwise. If you cannot turn the crankshaft with a wrench easily, then the starter can't either. Turn the crank all the way around to check for something preventing cranking.
Is the battery still enough power to crank at normal speed? If it's already too low, recharge it, and try again.

Hard starting cold


Is cranking speed slow? Do a voltage drop test on battery cables.and a high output amp meter to test starter draw. normal ampere draw should be 250-350 amps cold and 300-375 amps hot as engine turns these readings should drop to 200-250 amps if not bad starter.

After sitting for a while I can get about 2 normal sounding cranks when I turn the key and then nothing. I still have power so I don't have a clue. It started when my wife pulled out of the driveway...


no ,you dont have power.
the battery uses 100 to 500 amps to run the starter.
normal is 100amps , on warm day. really the starter is the ACID test of any battery.
the ignition uses 5 amps. (nothing) same with lamps. trivial currents.
the battery is not charged, , so charge it. or...
if the battery is bad , it will not take a charge and hold 12.6volts.
try a known good and charged battery in car. that work?
yes?
then either the battery was bad, or you left on lamps?
or the charge system failed and battery drained.
bad cranking 101
1: bad battery.
2: discharged battery (or any reason)
3: bad battery connetions, corroded lugs.
4: charge system failure.
5: phantom drain (dark current) or left on lamps over night.
1: put in fresh good battery.
2: start car, is voltage across battery terms near 14.7v?
yes, good charge system.
no?, its 12.5v, charge system is dead.

1998 Saturn SL not sparking and not starting


onepx.gif 1. Test the AC voltage output from the Crankshaft Position (CKP) sensor while cranking at a normal speed. It should produce at least 250 millivolts.

2. Retest the voltage at the Powertrain Control Module (PCM) on the Yellow wire in terminal D13 and the Purple wire in terminal D14.

let me know please thanx i hope it fix

89 Ford F250 won't start


To check battery you would need a multi meter to determine how much power is in the battery and how much power is being drawn off the battery when trying to start.Can you borrow a good battery?If you try to jump start the vehicle from another vehicle and engine struggles to turn over its not likely to be a battery fault but an issue with the starter motor or partialy siezed engine.Pull all the spark plugs out and see if the engine will crank over any easier.To check ignition remove spark plug,push removed plug into no.1 H/T lead and lay it on engine block(good earth)crank engine and you should be able to see good spark at spark plug end.Being unable to crank engine at proper speed will not give you proper result so cranking issue must be dealt with first.
