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.

you may need to have the PCM programed to the new injectors.

SOURCE: I have a 2002 Kia ECU system fuse burning all the

Assuming the correct fuse is being used, there is a short somewhere in the wiring leading to the ECU or in the ECU itself. If no modification has been done to the wiring (such as aftermarket radio or alarm), the ECU may be bad. A dealership may be able to test the ECU if you remove it, but will probably charge for the service. You may be able to find a cheap ECU at a junkyard for the same cost. You can use an ammeter to check power consumption at the fuse slot. If there is more than rated amperage consumption with the key on, engine off and ECU in, there is a short. Remove the ECU and recheck. If there is more than about a hundred milliamps with the ECU out, the short is in wiring. If not, the short is in the ECU. If there has been modification to the wiring, check it for shorts or exposed wires, and remove the mods if possible. You may also be able to get a pinout for the ECU from Kia and check for incorrect shorts to ground on each pin using a self-powered continuity tester.

SOURCE: 2002 Kia Sedona. Car wont start. We change to new

Did you check the ignition system? The module and the ignition usually at fault when u can't start the car! U have replace the ECU w/o any scanning by the dealers computer to check wuts wrong w/ ur car? That'll be a shot to the moon! Pls go to ur nearest dealer and have ur car scanned by their computer analyser! hope that might help u! taaah!

Hi i got a gwm 2.8 TD not starting.check all fuses.tested injector pulse with diode test light and no pulse found.tested ecu with another gwm 2.8 and is starting with my ecu.


Not sure what a diode test light is, but I would check with a DC voltmeter for a 12 volt pulse. The pulse is very short in duration, so you might not see it. Check for spark at the spark plugs. If fuel pump is bad, you won't have fuel pressure. There are numerous reasons for an engine not starting.

2011 swift 1.5 no injector pulse no spark


blown fuse. ; is first, as per always.
2nd is scan it, did you scan it yet? that is always 2nd.
all efi engines, all ECU , all cut injectors for (noid lamp test dead?)
you said pulse,does that mean fuel pulse or electronic pulse to injector coil..... ? all injectors dead. or just 1. same for spark.
toss coin land, noid dead. all noids
loss of. NOID signals.!
1; spark
2: lose of CMP or CKP signals (cam or crank senders)
3: ecu sees wide open throttle it cuts fuel 100%
4: ecu bad, is CEL lamp dead key on? scan it.

Which sensors tell the ECU to send a pulse to the single TBI injector?


You want a simple answer but there is not one. The ECU looks at many things to determine what (if any) pulse is proper. Any sensor which sends no information or info outside of normal limits can prevent pulse. No info from crank/cam sensor is common issue, Bad EFI fuse or relay can do this. Bad ECU ground or other ground (Fuel rail) can do this. Many sensors can be tested with ohm meter.

I have a 2006 mercury montego 3.0 front 3 cylinders are not getting fuel


If there is fuel pressure at the back of the injectors for those three cylinders, check to see if the injectors are receiving pulses at their electrical connectors. If they are receiving pulses, the injectors are clogged and need to be cleaned or replaced (likely just cleaned). If they are not receiving trigger pulses, check the wiring harness for damage. If there is no damage to the wiring harness, the ECU is not functioning properly and should be tested.

Jaguar xj sport 3.2 no spark or injector pulse


If ECU has crank signal and engine turns over, ECU should give injectors a pulse and trigger the ignition. If not ECU might be bad. You should check power and grounds going to ECU. There are usually multiple power and grounds going into ECU

I have a 1988 300zx non turbo 3.0 just replaced the ecu thinking it was the problem but its not. My car will turn over and it sparks, tested the fuel pressure and it makes 42lbs so thats not the problem...


The pulse to switch the coils comes from the crankshaft sensor via the ecu. Pulse to switch injectors comes from the CAMshaft sensor via the ecu. Check injector wiring plugs and confirm there is an ignition live of 12v at one side. Other side should have an earth pulse when cranking.Once you know which is missing you can trace the fault backwards. ( if no ignition live then check wiring, relay, fuse etc) if no earth switching check camshaft sensor and wiring.

How to test a coolant SENSOR


Hello there
This should help you out a lot ok

To test, use a high impedance volt-ohmmeter. Resistance should be less than 1000 ohms with a WARM engine (examples = 212* would be about 185 ohms, 160* would be about 450 ohms, 100* (not warm enough) would be 1,600 ohms).

> What does it do? Adjusts the injector pulse widths (Colder coolant temperatures result in longer injector pulse widths and richer air-fuel mixtures). Compensates for fuel condensation in intake manifold. Controls engine warm-up idle speed. Increases ignition advance when engine is cold. Energizes the EGR valve solenoid to prevent flow of vacuum to the EGR valve. Update: Basically - this sensor functions by providing a resistance-to-ground circuit that the computer (ECU) uses to determine how much fuel the engine requires. (The hotter the coolant - the lower the resistance.) The resistance of the sensor is read by the ECU which in turn adjusts the air/fuel ratio as close to 14.7:1 as possible. When a coolant temperature sensor fails (open circuit / no continuity) the high / infinite resisitance will cause the ECU to falsely read the max low temperature of -40 degrees F. The ECU then tells the injectors to enrichen the fuel mixture because it thinks the temp is really cold when it really isn't. A short to ground would cause a 'no-resistance' fault causing the ECU to think the coolant air temperature was extremely hot and lean out the fuel mix.
