Sounds to me like either a timing belt/chain broken or a bad ecm or brain box.

SOURCE: 2000 kia sportage. no start no spark no injector pulse.

check both of your fuse panels for a blown fuse. there's 4-5 that control the fuel pump, engine sensors, fuel injectors and such. one of those may be blown and not letting the rest of the system function. one panel is located under hood, and one is under the dash on drivers side. when you take the covers off they have the fuses numbered and tell what they control.

SOURCE: 2001 mazda protege will not start

well, with all that you have changed the only two possible things that are left PCM and the ECM....

Do you have an alarm system on this vehicle? If you purchased this car second hand it may have something that is inhibiting the engine from firing. From what you have told us here that would be where I would start looking.

I really hope this is helpfull

Check for fuses/power/ground to the engine computer (or injector drive computer) whatever the case is.

Spark, fuel pump, and starter all are independant of the fuel injection computer.

Either the computer itself has gone bad, or it is not receiving power or ground, or wiring to the injectors might be bad...

Sherylpuha,

Have you checked the coil from where the spark comes from and the computer sensor fuse block?

97 Oldsmobile 88 after driving once motor is shut off will not crank until cool, had the control module tested it came back good, replace fuel pressure switch and still will not crank until cool?


You will need to replace the crank angle/position sensor near the crank pulley. A photo of the sensor is attached. The sensors wear out due to heat and cold cycles and internal corrosion.

Why does my 1999 buick lesabre motor stop while driving but restart after a frew minutes?


it sounds like you might have a crank sensor that is going bad. When it does not start check for spark and injector pulse. If both are missing than it is very likely a bad crank sensor. If there is no spark but injector pulse than the crank sensor is working and you may have an issue with the ignition module.

Wont start. it has injector pulse but no spark


is there power and ground to the coils?

If there is injector pulse than the crank sensor has to be good. Injector pulse and spark are both calculated off from the signal from the crank sensor.

Checking for power and ground to the coils is a good place to start. If that checks out than either there is a wiring issue in between the PCM and the coils or possible the PCM has failed.

Why does the fuel injector receive no pulse for 1998 ford explorer 4.0 motor


The 6 cyclinder motor has 6 fuel injectors. If your not getting pulse Electrical grond to an injector wire theirs a likly chance your not getting it at another. If your getting no pulse at all the engine won't run. Does the check engine light on with the engine running? What meadod did you determine that it had no pulse? Remove one injector wire one at a time with the engine running? If it's not running at all then the no pulse can be a common system part like the crank senser. Does the engine get spark? Most of the time pulse and spark are hand in hand so if the crank senser were bad it's not going to have s[ark either.

No gas coming out the injector and there is gas pressure to the injector?


Is there an injector pulse going to the injector?(an electrical pulse to fire the injector).
Is there spark at the plugs?
If the pickup in the dist is faulty you won't have either one.
If your vehicle uses a crank pickup with or instead of dist pick up....if it is defective ....no pulse.
The above is 90% cause of no pulse....other is computer problem 10%.
If you do have a injector pulse and no spray.....and have fuel pressure....change the injector.
A quick check for spark is spray a little starting fluid in it.....if it starts on the fluid....spark is present.
