Tip & How-To about Alfa Romeo 164
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.
