SOURCE: engine died & wont start no spark ignition coil tested good

try your ignition module in the distributor much more likely. just install rebuilt distributor if that is the problem , if you just replace module the main distributor assem will **** out shortly after.
Make sure you check for broken timing belt also it is one of those two!

1. Monitor the 5v reference, Gray wire to the Throttle Position Sensor (TPS) with a Digital Volt Ohm Meter (DVOM) set to the MIN/MAX setting.

2. Monitor the TPS signal circuit, Blue wire with a DVOM. Voltage should range smoothly from approximately 0.44 to 5.0 volts as the throttle is opened.

3. Tap test the Electronic Control Module (ECM) and see if the codes come back or if the engine reacts.

possible causes wiring or Powertrain Control Module (PCM)

Car Won' Start


Car won't start?
First thing would be to check all your fuses. Most fuse boxes are located under the driver side dash panel. Some cars do have an extra set of fuses on passenger side kick panel (foot area on door side)
If all fuses are good, then next thing would be to test your relays with an ohmmeter.
If all your your relays and fuses are good, you will want to check for fuel and spark. A car needs air, fuel and spark to run.
To check for spark, you can purchase and use a spark tester.
If you cannot obtain a spark tester, then the next best thing would be an ohmmeter. You can test the power coming from your coil packs or distributor depending on what you have. On distributorless vehicles (one with coil packs) the coil pack are attached to an ignition module. This module is powered by the Crankshaft Position Sensor. This sensor can be tested with an ohmmeter. The Crankshaft Position Sensor is the first thing to be tested if you have no spark in any cylinder. If you have spark in some cylinders but not all, then check the coil pack (1 pack per 2 cylinders).
If you have a distributor, test the coil that provides the spark.
If you have plenty of good strong spark, then the next step would be to check for fuel.
Fuel system consists of Fuel Tank, Fuel Pump, Fuel pump Relay, Fuel Filter, Fuel Pressure Regulator and finally carberator or injectors.
Fuel injected systems have a fuel rail. On the fuel rail is a test port for fuel pressure. If you have a fuel pressure tester you can test how much fuel pressure you have. Or you can place a rag over the valve and press it in to see if there is pressure. If not pressure, check that pump is running. You should hear it run for a few seconds when key is first placed in the ON position. If pump is not running, check fuses and pump relay.
If pump is running but fuel pressure is low, check for leaks, plugged fuel filter, or leaky injector.
If your check engine light is on, then you likely have a faulty sensor or circuit and should have the engine codes read with a code reader/scanner to pinpoint exact problem area.

I have a Fiat Siena 1.6 16valves ELX 2007 model.The problem with it is that the engine overheats.And the rev goes up and down on its own without me applying the accelerator.What could be the problem?


Over heating may be caused by a faulty thermostat, a blocked radiator, a collapsed radiator hose - or cylinder head problems.

The same symptoms can also be caused by a faulty sensor - particularly a faulty oxygen sensor. All the sensors work together- fuel-air .. and a lean (weak) mixture can cause overheating. It sounds as though your car is struggling to get the air/fuel/timing mixtures correct.

Rather than change parts in the hope that you can cure the problem, ask somebody to do a diagnostic check on the engine to identify any error codes.

Please help. I have change my plugs. The car dont want to start. There is no spark. Fiat Siena 1.2 2005


It's not the plugs. I would look at the coil/s or ignition module. Also check for codes. Could be the crank sensor is bad.

check to see if the cam shaft is turning ( broken timing belt /chain) run the fault codes to check for problem position sensors. check immobiliser is operational.

My car will not start my lights, radio work its not the battery. I recently replaced the starter, the altenator, battery, fuel pump catalyic converter. when i turn the key there is no noise it won't...


Sounds to me like the starter or starter relay, OR did you check all the fuses? When the starter doesn't click or turn over the engine it is likely a problem with it or the power supply to it. Start with the easy thing. check the fuses, then the relay.
The P0300 is usually caused by something other than the spark plugs or coils. A fuel/oxygen sensor can cause this code. I would say that doesn't have anything to do with not starting.
Good luck.

Thanks for using FixYa.

My ASD fuse is making a clicking noise and vibrating. What is the function of this fuse?


ASD fuse is called an AUTOMATIC SHUT DOWN FUSE. The ASD sense circuit informs the PCM when the ASD relay energizes. A 12 volt signal at this input indicated to the PCM that the ASD has been activated. This input is used only to sense that the ASD relay is energized.
When energized, the ASD relay supplies battery voltage to the fuel injectors, ignition coils, and the heating element in each oxygen sensor. If the PCM does not receive 12 volts from this input after grounding the ASD reley, it sets a Diagnostic Trouble Code (DTC).
