When I turn on the igniter comes but won't do the burner flame


The heater will not ignite, but this problem could have several causes! Do you mean that the motor is running, fuel at the nozzle but although there is a spark, the fuel does not ignite? This could be caused by low pump pressure, loss of spark could be the HT cables, or the ignition transformer. Is the electrode in good order?? An intermittent spark could be faulty electrodes or ignition transformer. Is the fuel clean and the correct type?? Is the fuel contaminated with water, is the fuel filter clean?? Dirty fuel could cause this problem.

Engines with Starting Problems


All engine regardless of manufacturer need three things to start and run. Air, Fuel and Spark, lets look at each one.

Air- this refers to air intake on four stroke engines this intake is created by the piston pulling in air with the intake valve open. You must have a combustion chamber that is sealed, meaning that there are no compression leaks from the head gasket, or from the valves. The valve timing must also be correct, meaning that the intake valve is open while the piston is going down on the intake stroke. Associated parts include the air filter, air intake manifold, intake valves, pistons and intake hoses.

Fuel- this refers to fuel supply, with out fuel an engine can not run, the fuel supply has to be correct for start and run conditions. Associated parts for fuel are fuel pumps, fuel pump relays, fuel pump fuses, fuel lines, fuel injectors, fuel hoses and carburetors.

Spark- this refers to the ignition source provided to ignite the fuel mixture. Spark is generated from an ignition coil and released in several ways. Associated parts to ignition are the ignition switch, coil, ignition module, crankshaft position sensors, camshaft position sensors, spark plug wires, spark plugs, distributors, and ignition points.

If you have a vehicle in which the engine does not run one of these three things are missing, otherwise it would work, so remember to always check the basics first it will lead you to your problem faster and cheaper.

Engine starts runs few minutes then stops running and wont start baack up til a few minutes go by


This can happen when an electrical part gets warmed up and fails. Possible causes are the fuel pump, the ignition coil, ignition control module (or igniter as Honda calls it), crankshaft position sensor to name the most common. The first causes a fuel problem, the last three are ignition related and cause loss of spark at the spark plugs. What you could do is check for spark on one of the spark plug wires while someone cranks the engine over, immediately after it shuts off and won't restart. If you have no spark, then you know it is ignition related. If you do still have spark, it could be your fuel pump. The best check for that is to check the fuel pressure with a fuel pressure gauge.

Missing problem


Missing problem requires to check the following systems and components:
1. Fuel system. (Fuel pump, fuel filter, fuel injectors).
2. Ignition system. (Spark plugs, spark plug cords or wires, ignition coil, distributor (cars with distributor type ignition system, rotor, distributor cap, ignition amplifier), Coils On Plugs (COP) and correct sequence of the spark plug wires and or Igniter connectors.
3. Air leakage in the intake manifold.
4. Detached vacuum hose.
5. PCV Valve.
6. Servo brake booster pipe or diaphragm.
7. Valve clearance.
8. Cylinder compression.
9. Contaminated fuel.
10 . ECM.

My 1990 hond accord will turn over but wont start can you please help


MAKE SURE SPARK PLUGS AND WIRES IN GOOD CONDITION, REPLACE DISTRIBUTOR CAP AND ROTOR,CHECK FOR SPARK AT SPARK PLUGS,IF YOU DONT SEE SPARK CHECK TO SEE IF POWER GOING TO COIL IF NOT CHECK IGNITION FUSE.IF FUSE OKAY AND POWER GOING TO IGNITION COIL,COIL FAULTY OR IGNITER UNIT FAULTY. CHECK FOR FUEL PRESSURE MAKE SURE FUEL FILTER BEEN CHANGED.FUEL PRESSURE SHOULD BE 40 PSI. IF YOU GETTING SPARK AND FUEL. YOUR IGNITION TIMING OFF OR VALVE TIMING OFF DUE TO A WORN TIMING BELT.

What does the ignition coil do?


the ignition coil changes low voltage from the battery (12 volts) to high voltage (about 50,000 volts) to fire the spark plugs and ignite the fuel in the engine cylinders and drive the piston down

Replace egr valve still wont start


PROBLEM COULD BE FAULTY FUEL PUMP OR IGNITION MODULE.CHECK FUEL PRESSURE SHOULD BE 41 - 47 PSI. IF NO FUEL PRESSURE TO LOW REPLACE FUEL FILTER.STILL LOW FUEL PUMP FAULTY.IF FUEL PUMP DONT RUN CHECK FUSE AND RELAY.IF FUSE RELAY GOOD PUMP BAD.IF FUEL SYSTEM OKAY USE A SPARK TESTER TO CHECK FOR SPARK AT SPARK PLUGS IF NOT CHECK IGNITION MODULE FUSE IF OKAY IGNITION MODULE COULD BE BAD.USE A CODE SCANNER TO CHECK FOR FAULT CODE IN PCM AND IGNITION MODULE.THIS SAVE YOU FROM SPENDING TOO MUCH MONEY.

WONT START


Not so many reasons she won't start. 4-Strokes are Simple!

Here they are:

Motor:
Fuel Tank-> Fuel Line-> Fuel Filter-> Carb-> Intake (Valve)-> Piston-> Exhaust (Valve)-> Muffler

Carb (Old Style):
Fuel Side:
Fuel Bowl-> Float-> Needle Seat-> Fuel Ports (Venturi)
Air Side:
Air Filter-> Carb Air Intake-> Butterflies (2)
(Clean 'em ALL!)

Hardware (Motor):
Rotor (Magnets)-> Magneto (Ignition Coil)-> Spark Plug Wire-> Spark Plug-> Cylinder Head (Spark Plug Ground)

Ignition:
Kill Switches (Seat, Clutch, etc.)-> Spark Plug/Ignition Coil-> Ground
Key Ignition-> Battery->Starter/Generator

If one of those fail.......= Non-Starting 4-Stroke!

Fixes-
Fuel:
You are either getting too much, or too little. Too much = Carb.
Too little = Carb. Therefore, tear down the Carb (COMPLETELY-Careful!) and clean it up.

Electrical:
Grounding out the System (Kill Switches)
Battery-> Ignition-> Starter.
Magneto->Plug Wire->Plug (Check 'em all!)

Heater wont ignite. Has fuel coming out front of


if the spark plug is sparking it is hot enough to lite the fuel.is ther dirt in fuel tank???is there water in the fuel???? what is the air pressure set at????is the nozzle clean and spraying correctly?????any of these will cause the heater not to fire.not the spark plug.

1996 Nissan Sentra doesn't have sparks


Hi and welcome to FixYa,

Initially, to my understanding, 1995 to 1997 Sentras share the same ECU (except the '97 1.6L). Below ECU pin configuration may be of help.

Additionally, depending on the regional version that you have, the '96 Sentra may be sharing the same electronic ignition with an Altima. If so, this might interest you.

Good luck and Thank you for using FixYa.
