Default Troubleshooting Common Problems

Main relay symptoms are:

  • Car won't start when hot outside
  • Car won't start after parked for just a minute.
  • Car starts but quickly dies as the rpm shoots to 1300 rpm. A second cranking attempt will crank but no signs of catching or any strong rpm movements.
  • Once started the car won't stall. After the car runs for a couple minutes, the symptoms return after shutting off the engine.
  • Windows have been rolled up on a hot day when problem occurred.
  • The heater was on before turning the car off.
  • Tapping your fingers or keys on the main relay will start the car.
  • No (humming) sound from the fuel pump the moment the ignition switches ON.
  • No click sound after the ignition key turns on or
  • No click sound two seconds after the ignition turns on.
  • Check engine light comes on (rare cases) or stays on longer than usual and no sparks (electronic timing only.)
  • 10-15 of waiting and the car pushed to a shade, will usually start.


Ignition switch symptoms are:
  • The dash will go dark when it dies (no warning lights, no shift indicator, no electrical).
  • Car stalls then can be started, then stalls after driving or idling for a few seconds or minutes.
  • Car runs fine when the key slightly held at start position or part way between start and ON position. In rare cases, this symptom is similar to a bad main relay.
  • Ignition (electrical) switch is hot.
Igniter/ignitor symptoms are:
  • The tachometer quits abruptly or jerks around before stalling.
  • The car quits abruptly or jerks around before stalling.
  • Engine cools down and starts, stalls under normal operating temperature.
  • Oki igniter brand was installed.
  • No spark at the coil.
  • All dash warning lights shows up during stalling.
Coil symptoms are:
  • No spark at the coil.
  • Cranking shows no signs of sputtering.
  • The RPM needle shows an immeasurable hint of life.
  • Car won't start the next day and from then on.
  • The distributor was abused before it died.
  • The coil looks extremely dry, melted, flaking or cracking.
  • All dash warning lights shows up during stalling.
Fuel pump: Symptoms of a bad fuel pump.
  • Turn the ignition switch on and no hum is heard for the first 2 seconds.
  • Car stalls while idling or cruising above 1 mph. Sometimes car comes back to life.
Flooding:
  • Spark is found and can smell gas.
  • Engine will crank but with no signs of sputtering but may sputter on one or two cylinders.
  • Once started, a plume of smoke is seen from the tailpipe and idles rough before settling into a smooth idle.
  • After being able to start the car will restart just fine.
  • Press the gas halfway or fully down to release fuel vapor and allow more air to balance the air/fuel ratio usually starts.
  • Some late model cars have the ability to shut off the injectors for a number of seconds when starting at full throttle. This clears the combustion chamber. Check your owner's manual.
Moisture:
  • Engine cranks but won't start when it rains.
  • Signs of moisture on the ignition wire.
  • Shutoff the car and come back a couple hours later will start.
Bad starter solenoid, dirty console, clutch switch:
  • Will only click at the starter solenoid but won't crank (motor/starter won't spin.)
Corroded battery terminals, bad ground straps, bad battery or alternator charging symptoms are:
  • Engine does not turn over or turns over very slowly then quits.
  • Sometimes the dash will go dark or dim when attempting to start (no warning lights, no shift indicator, no electrical).
  • Usually a single snap is heard from the battery post when attempting to start followed by no relay clicks, warning lights, no electrical.
  • Usually a jump start form another car will start the car is an indication of a draining battery, bad alternator or battery. The voltage should be 14 - 14.4V at 2000-rpm.
TW (coolant temperature) sensor:
  • Won't start when cold outside or on a cold engine.
  • Disconnecting the TW sensor usually starts.

Bad ECU or ECU at fault:
  • No spark and check engine light is on and stays on.



Low compression:
  • Won't start when stored for a month or so.
  • Car just overheated and quits on its own.
  • Compression reads low. (normally 100-180-psi should start)
  • Pouring a cap of motor oil into the cylinder usually starts. (Don't attempt if not certain.)
  • This is not categorized as intermittent.



if you guys come up with any other good ideas that i cant think of at this moment let me know

Why did you change your fuel filter? How are your spark plugs? worked on a 90's Chevy pick up about a month back in class that when you put it in gear the rpm would drop a lot. Replaced plugs wires ad fuel filter but didn't help. Found out the fuel pump was going out and didn't have enough flow.
