Engine fails to start

There are some things you can do to fix the problem. Check battery connections: Even if the batteries are charged, it is important to make sure the battery cables are clean and tightly connected. Components with loose or damaged wires can interfere with efficient energy transfer. Check fuse relays: Check the vehicle fuse box for any blown fuses or defective relays that could affect the starting system. Transmission Position Sensor: If your vehicle has an automatic transmission, the transmission position sensor (neutral safety switch) may not work properly, preventing the vehicle from starting into gear Start the vehicle in both park and neutral and check that is there any difference. Check for safety system problems: Some cars have safety systems that can shut down the engine if there is a problem. Make sure the security light on the dashboard behaves as it should and try to use a spare key if there is one. Starter Motor: The starter motor may be faulty. Turn the key and listen for the clicking sound. If you hear a rapid clicking noise, it could indicate a faulty battery or a faulty starter motor. Hearing a click once could indicate a problem with the starter solenoid. Ignition switch: The ignition switch sends power to the starter when the key is turned. If faulty, it can prevent the engine from cranking. Try to notice a change when you change the key. Fuel Supply: If the engine cranks but does not start, there may be a fuel issue. Check the fuel level and make sure the fuel pump is working properly. Check engine light: If the check engine light illuminates, a diagnostic trouble code (DTC) may be stored in the vehicle computer.

bad fuses is first (done) good.
head lamps work key off and ON?
glow plugs dead?

what means cranks
not even cranking at all
the starter motor DC spins called cranking
then starter motor cranks the crank shaft fast. if does the engine starts if fuel is there and glow plugs not dead.
do not use the word crank for start.
starts and runs and sustains running is what matters
if the starter fails that is simple causes, not like dead engines and 50 causes see?

the starter will not spin if
battery dead or weak or 4 lug ends loose or rusty
starter relay not bad.
PRNDL switch (A./T box) fails in park we next crank it in Neutral


I fail to understand this line
"after trying a few times it's not even cranking at all.? starter motor dead? try to more clear ,?
starter RPM is near 300 on most cars/trucks. 500cca or more.
starters do all these things, for sure, failing: below:
GRRRRRRGGRRRR good sound.,,NORMAL:
dead silent starter. but relay may click or not.
clicks its solenoid , weakly , nothing else happens.
chatters the solenoid but cranks shaft dead. 8v at battery caused.
loud bang!, starter sound on seized engine, or starter shims wrong.(if)
or starter itself is pure Seized, up.
starter spins crazy fast, not crankshaft at all
caused by bad starter drive gear & its mate, flywheel ring gear
even a dirty starter drive pinion jammed up in gunk there. can not slide fully.
starter is slow, as is crank shaft bad battery or bad starter, yes starters can fail and be weak, or 100% intermittent, same as PRNDL or relay

if starter motor ever fails on any car (not sinkn hondas)
the next step is crank in neutral foot on brake.
PRNDL, the P switch fails first and the N, mostly not.
all tow truck drivers know this.
and use jumper cables to prove battery is not droppng low.
under load, below 10vdc cranked is not good as computers can go off line below that ending fueling.
Solenoid main chatters at 8vdc., spec on them actual. and me testing them.

see this gem of voltage plot in time,
scope view or GDMM
see the 10volts there? this drop is battery cell resistance only
normal.

Sounds like the relay in the starting motor circuit has failed, or a starting motor/solenoid problem - have them checked. This can also be caused by a problem in the ignition switch.

bad starter motor or soleniod
hum or whir or clicking
means starter is not throwing out to the flywheel teeth to turn the motor over

or cable from battery to starter needs inspection

do the dashboard lights go out when key turned to start? when you say nothing happens,is there a click? does the motor turn over,but not fire? is it an automatic,meaning is the gear inhibitor switch preventing starter from working?have you tried a jumper battery?putting a jumper lead from the battery earth to the engine ground helps sometimes,if earthing cables broken

The battery is charged up, but still remains suspect, because a failing battery cannot hold enough oomph to crank the motor, even after charging. So -

- failing battery, especially if 3 yrs old or more
- worn starter solenoid contacts
- failed starter solenoid coil
- dead spot in starter motor windings
- bad contact at either end of battery ground strap

There is a crude test. Turn on the headlights and try to crank the motor. If the lights dim down a lot, it is the battery at fault.

Your battery is not providing enough cranking load for the starter motor. First try cleaning the battery terminals disconnect negative terminal first.

What happenes when you try to jump start the vehicle? If it starts - then it is most likely the battery or alternator. If it doesn't start then the solenoid or the starter or the engine. To get it down to the starter or engine - disconnect the serpentine belt and turn the crankshaft with a wrench. If it turns - then it is your starter/solenoid.

The starting system consists of:

• starter motor
• starter switch, part of the ignition switch
• starter motor solenoid relay switch
• starter solenoid
• starter drive

When you turn your key to start your engine, it just clicks, right? If so, more than likely this is due to a bad battery. Even though your battery may appear to be fully charged, it may have a dead cell, or worse. If you get a jump, does the vehicle start? If so, replace your battery.

Possible sources of the problem if the engine does not crank or the relay clicks:

1. Battery
2. Starter motor
3. Starter motor relay
4. Ignition switch
5. Damaged fuse
6. Anti-theft system
7. Circuitry

Check all battery connections for corossion, battery to motor and battery to body ground for corossion under mounting bolts. Also check motor to body ground strap. Also check battery wire and all otherwires on starter solonoid. Check condition of battery, even if the dashboard lights up your battery can not have enough juice to turn car over to start.
