Clean battery cables and maybe have starter tested. Starters as they age drag and draw more amps. (If that was what you were ref to hard starting) You might do a complete tune up - plugs, wits all filters and fluids & run a good fuel system cleaner through it. That would give you a good "ground zero" starting point.

My 2005 Suzuki Aerio won't start. I know that there is power as the lights, radio, ect are working when the ignition is turn on, but the car will not turn over. Side note, the heater blows even though it...

IS tthis a DIY question? or just want guessing? ill pretend DIY/.
no, the car will not crank.
cranking uses 100 amps of current,
the HL , maybe 10amps, 10x less.
turn over means nothing, cranking matters
both the starter and engine spin, "turns over": (1 can and other might not)
starting is a whole other matter, as is sustained start, called running.
crank?> start, started, running, 1,2,3,4.

the heater blower runs, key on, but the heater switch is off.
seem like the controller is tad upset, (lets fix engine first) and fix blower later. (my bet is it wakes up when battery is happy)

my guess is car has and automatic transmission, right>?
and as such to crank it must do so in, park and in Neutral.
does the engine crank in NEUTRAL. (hold foot brake, keyon, shift th N. ) crank now?
1: check fuses yet?
2: check rested battery voltage yet (meter) 12.6vdc.?
if less battery is bad, or only discharged. if yes, charge it?
no charger use jumper cables to crank car. got cables?
call AAA tow they jump start it? no AAA?
barrow a charged battery and try that, ok battery is charged and it will not crank,,, ,good progress now.
3: i next hot wire the starter solenoid. (some cars this is very hard)
check for about 11vdc at starter key line cranking.
0v means its dead.
hot wire that small starter wire, there, cranks now , key off
the starter is good.
now check voltage at the left side of P/N switch, Park/neutral.
12vdc id good, cranking, 11 is too.
if you cant get at least 11v out of switch 20. that means
the P/N switch is bad, (11 or more input)
(battery is good, solved that in test 2)
so bad transmission park neutral switch called the KEY line.

No electrical power

My guess is the trans won't shift because of no power. There is a safety switch that is activated by the brake power means no lights and no lights means no shifting. Solve the power issue and you should have the trans working again.

For power it's time to get a probe and start at square 1. Battery? Have you tested it? Cables solid and CLEAN? These get overlooked a lot. Electrical is a hard one to solve over the net. But they are not hard to solve...just can be time consuming.

2002 pt cruiser. Just replace the battery a week ago and the cables, the car runs fine with the battery disconnected so it cant be the alternator. when you put the key in and turn it on without starting...

I had the same problem. Check the wire in the terminal on the starter. That terminal is not crimped well enough around the wire.
It is pretty hard to get to, but removing the air cleaner and battery helps. When the PT won't start, have someone get ready to turn the ignition switch to start, reach down the left side of the battery (facing it) And give those 2 red wires (about the size of a lead pencil) hard yank just after your helper turns to start. You'll pull them out of a snap in wire holder, (which you can put back later when it is repaired). This should put the wire to the starter in a bind thus letting it start. You may see some sparks as the contact is made, or if loose enough, pull the wire out of the terminal. If this happens, you found the problem. Hope this solves your problem.

Intermittent starting problem. Seems to be the switch that prevents car from starting in gear. After replacing battery didn't solve the problem, I discovered I could start it after I fiddled with the gear...

Switch should be on the transmission. Which transmission determines the location. Chrysler baded units have the switch on the drivers side near the rear corner above the pan rail. AW units have it on the right side, opposite where the linkage on the drivers side goes into it.
Either way, it's called a neutral safety switch.

2004 F350 6.0L starts rough and runs rough until warmed up. When it was newer I could start in cold weather and run smooth with full power right away. Now it has no power at all until warm and is hard to...

What tells me, is that the thermostat is staying open after
your done using the truck
When you start it up cold, it takes longer to warm up the area
near the coolant temp sensor,which is part of the system
to put the PCM (computer) into closed loop
Closed loop is when you leave a computer fuel stratagy and
the O2 Sensors take over fuel control

Hard to start----

Need spark plugs that have not been in the motor over 60,000 miles
Spray the throttle plate with CRC Throttle Cleaner
Spray the MAF Sensor with CRC MAF Cleaner
Need all ducting in place,no vacuum leaks and a clean air filter
Make sure your O2 Sensors are tight
A fuel filter not over 3 years old
Hope the coolant temp sensors works correctly

Anything more gets too technical

Service light comes on 270 000 km car dies while driving put new plugs, lot of the time ahave to turn key 20 times then she starts


The problem with car starting is not only related with the plug, it also have to do with the battery sometimes, when the battery does not hold a charge, then the car will take long to start. While trying over time the battery is trying to pick a little charge to be able to come on.

If your engine has a carburetor, the hard starting problem is most likely choke related. If the engine cranks normally and the spark plugs are not worn or dirty, the choke probably needs to be repaired or adjusted.
The choke may be set too rich or too lean. Either way can cause hard starting. Inside the choke housing is a bimetal spring that regulates the tension on the choke according to temperature. If this spring is broken, the choke will not operate. If the choke linkage is rusty or jammed with varnish deposits or dirt, it may stick or not operate smoothly. Cleaning with carburetor spray or solvent may help alleviate a sticking problem.
On older fuel injected engines, a separate "cold start" injector is used to spray additional fuel into the intake manifold when a cold engine is first started. If this injector is not working, the engine can be hard to start. The injector is controlled by a timer and relay, so if either of these components is defective it can prevent the cold start injector from doing its job, too.
If your engine cranks slowly, your cold starting problem is not fuel related, but may be due to a weak battery, loose or corroded battery cables, or a weak starter.
Check for obvious problems first. Remove, clean and inspect the battery cables (both ends). Then check battery charge and condition. (More information on the condition of your battery and battery recharging is available.) If the battery charge is low, recharging the battery may temporarily solve your problem. But there's a reason why your battery is low. You probably have a charging system problem that requires further diagnosis. (More information on alternator is also available.) If your battery is more than four or five years old, it is probably near the end of its service life and needs to be replaced. A "load test" will tell you if it still has sufficient cranking capacity to provide reliable cold starting.
Slow cranking during cold weather (below freezing) can also be caused by oil that is too thick. A high viscosity oil such as straight 30 or 40 weight oil in the crankcase can make an engine very difficult to crank when the temperature drops. Switching to a lighter multiviscosity oil such as 10W-30 or 10W-40 should solve this problem.

Take care and good luck

Hard to start in morning, changed out cold start solinoid, no change,my truck is 86 toyota 4-runner w/22re engine

Buy a high amperage cold cranking battery! Typically there used in diesel engines, this will solve any hard starts!

2005 jeep grand cherokee has trouble starting, after it has been driven short distances (no seeming problem due to overnight or longer parking.) When fiddle with the gearshift and move slightly out of park...

Sounds like the neutral safety switch is either out of adjustment or is a bit worn out. Try starting in neutral when it does this...If that solves the problem, have the switch checked.
