    I do not understand how the e.c.m. could be fried without blowing fuses that control the e.c.m. and still allow the car to start and control all other perimeters of the car and only affect acceleration. Also the vsc light on the dash comes on.

    The fact that the car started and idled normally told me the fuel system was not the problem. The problem was a single 10 amp micro fuse on the ignition 2 circuit. this dead circuit activated the vehicle stability control dash light and the check engine light. Once i replaced the fuse the lights went out and the motor accelerates normally. Thanks anyway for your effort.

    Sorry but your diagnosis was wrong. The problem turned out to be a single 10 amp fuse burned on the ignition 2 circuit. Once i replaced the fuse the check engine light and the vsc light went out and the car starts and accelerates normally . Thanks for your effort.

Wow, what the heck did you do? Why was it jumped if the battery is at 13.5 volts? What is the voltage when it isn't running? Did you burn the jumper cables or the battery cables? Did you check the fusible link just past the battery on the hot wire? How about all the breakers next in line there. How about all the fuses? Is the linkage moving the throttle? The only thing you could have done is mess up the computer. I can't think of anything mechanical you could have messed up. I would check all that stuff, check the oil, the gas, make sure you don't have a anti theft switch somewhere, then if all that fails, get an obd2 scanner, borrow one from somebody or the parts store, and see if it will read something, before you go tearing out the computer and having it not being the culprit. Then if you are at that stage, see if you can get a donor computer or borrow one from somebody you know, ebay or junkyard, don't run out and buy a new one if you are not sure what it is, they are expensive. Hope this helps.

It indicates the fuel system related problem:---- Checking components of the vehicle's fuel system if the car will not speed up when pressing the accelerator. Under acceleration, the vehicle introduces more fuel into the combustion chamber to increase combustion and boost power output. If something inhibits delivery of fuel to the combustion chamber, the vehicle may hesitate, sputter or simply fail to accelerate. The vehicle's fuel pump may produce this effect as it starts to fail. Under normal operation, the pump forces fuel from the gas tank, along the fuel rail and into the injectors; as the pump begins to fail, it loses its ability to effectively move fuel and results in decreased acceleration. ------- Get the fuel pressure checked.If its low then this is faulty fuel pump and clogged/worn out fuel filter problem.As the flow becomes restricted, the vehicle experiences difficulty accelerating ------------- If the fuel system pressure is checked ok then this problem is related to faulty MAF sensor. The MAF sensor (Mass Air Flow Meter Sensor) is in charge of detecting how much air (in mass, not volume) is coming in to the engine, so the ecm computer can calculate the amount of fuel to be injected.

Thanks. keep updated for any more query.you can rate this solution and show your appreciation.

The inverted voltage has fried something in the ECM - sorry, you will have to replace it.
BTW the voltage is very low, a good alternator must deliver over 14.2 volts - ideally it should deliver 14.4.

    The ECM is basically a small pc - one single memory cell inside the processor it's all that must be fried for the entire pc to malfunction. The VSC light comes on because the ECM can't load the the firmware responsible for it (or if it loads it it results in errors so it unloads it) - again a sign of hardware malfunction.

My starter won't stop running after the car startswhat causes this


I need to know year--make--model?
Sometimes you can take starter motor off, lay in on the ground, hook up jumper cables properly from starter motor to battery, at the least, it should kick out drive gear and spin. When cables are removed the drive gear should retract. Could be something wrong with starter? It could be hung-up on flywheel for some reason? Could be a problem with ignition switch?
Usually two voltage circuits to starter motor, one comes from battery, hot all the time. The other circuit goes hot with key in the start position. The start position should be spring loaded, when you release the key, it should spring back to run position, so that circuit, at starter motor, is no longer hot.

2006 jeep liberty turn switch on and have power.starter and battery gd but wont turn over wont even click


the tests are all easy,
check fuses first, on all electric fails, starter ,charge and EFI are all electric systems.

super easy.
  1. jumper cable cranked with donor running car work?
  2. yes, battery is dead, or only discharged, charge it work?
  3. yes jumps but charge fails, bingo battery toast.
  4. so the jumper fails. in #1 , all that is a bad starting system. (not a part, the system)
  5. clean battery lugs. check fuses, and then hot wire the starter solenoid lug (dinky lug ,not huge one) (in park and wheels chocked keys off)
  6. ok that fails the starter is bad.
  7. ok that works. so the KEY line is dead. try starting in neutral yet?> bingo works, bad PRNDL switch on tranny side.
  8. the KEY line can be interrupted with some alarms, on a jeep it has Immobilizer that cuts fuel not cranking. so.... PRNDL switch bad or the key switch is self .
  9. Using any voltmeter to do the checks is a WIN. 12.6vdc is a charged battery is yours 12.6v rested/???????????

Saturn jumper cables hooked up backwards


Try charging the battery more. Even though your lights may come one, starting a vehicle requires massive amounts of amperage from the batter. It's possible that your jumper cables aren't a thick enough guage to supply enough power as well. Sometimes the vehicle you're jumping from might not have enough power to support your vehicle's starting power requirements.

Wont turn over or star


check all fuses first.
what transmission>?
jumper cable starts, use them to start car.
this tells you more in 1 step than anything,
if jumper to other running car ,starts your car, that means
your battery is bad, or weak or discharged.
if jumper cables starts fail check out the tricks here.

Loud clicking sound when i try to tunr it over


boost, hummmmm ?????????????
a charger with a boost button? (big shops have this)
or you mean jumper cable , jump started from a running other car?


my wild guess. is you always start fine, when jumper cable jumped.
this proves, the
battery in your car is BAD or is only discharged.
for 100 years now, same deal.
try a fresh battery off a good car.
works now, so ??? yours is weak or bad!

but started car , is the voltage 13.3. to 15v? a walfart $10 meter.?
no , then the charge system is bad (charge lamp on?)
note, i said system. not a specific part.

if the charge system is failing.?
  1. bad battery. tha'ts right alts do shut down with battery bad. (open or shorted battery)
  2. loose alternator pulley belt.?
  3. bad alternator wires. connections.? or bad battery cables.?
  4. scan the PCM most 2007 will report what is wrong with voltages and charge. scan it.
engine rpm way below normal at idle 800 is typ. good. 400 dead wrong.
battery cables bad.
battey cables lugs green with corrosion
someone put the minus cable far end to the wrong part>?
this minus cable has correct spot near the starter.
some fit to block others to stater , bolt or bell blots.
to frame is wrong, seen that , with lazy work.

1997 ford escort battery new battery dead overnight no electrical works no blown fuses jump start and cables start to melt will push start and run


Check battery cables are correct ! Prime suspect here ! Alternator may be damaged and shorting .. Don't drive any car that will melt jumper cables ! Something very basic wrong here.

I tried to start and all power goes out then I Disconnect positive and re connect there is power but it wont even click over and power goes out again


Your description does not rule out a bad battery. Make sure the cable connections are clean and connected correctly. Assuming this is all good check the voltage with a DC volt meter. A fully charged battery should test 12.85 Volts. If it is very near 12 or lower it is a week battery. With jumper cables or other means to get good voltage try and start it again. If is start you have a bad or week battery. If you get it to run check the voltage again while it is running. The meter should now read 13.5 -14.0 volts. If not above 13 volts it is not charging properly causing the battery to run down.....................

Won't start just clicks I have a new battery and attenltor


The just clicks is aways a bad connection causing low voltage at the starter, But the starter can be bad or ( hung in) Turn the engine by hand to se that it will turn if you hear a loud click when you turn the engine the starter ws hung, The starter being loose or worn out will let the gear climb up on a tooth of the flywheel. once cleared it may start right up. if there's alot of gear noise then the starter and or the ring gear (flex plate) may be damaged and need to be replaced. Low voltage is most ofte the cause, The old batery being bad or the new one being low, ( not charged) is most often the cause. After turning the engine, With jumper cables connected to another running car try again, Try hooking the ground cable of the jumper cables right to the engine block or case of the starter. if ti starts this way and not after you unhook the cables you have a cable connection from the battery to the block or the positive cable where it hooks to the starter bad

How do I jump start the car? The battery is dead


YOU DO.
Pull another car or battery to front of car ,,and get the set of jumper wires (RED/BLACK) Red lead goes to Poss term (the biggest one) on both cars ..
Then the black lead goes to the earth side of battery
When started let engine run for 2 minutes and then remove the Black lead first on both cars then the Red lead,then let it run for about another 6 minutes or take it for a drive ,,,but connect the leads around the correct way to batterys......
