Check the camshaft sensor. If the sensor is bad or not getting power, then the engine will not fire and the injector will not get a signal.
Been there before. The problem will be in one of the fuel injectors.
CLEAN THE INJECTORS. OR HAVE THE INJECTORS CLEANED BY A GM TECH.
Glow plugs and injectors are two different parts of two different engines. You may be referring to glow plugs or spark plugs. If you have a diesel engine, you will have glow plugs. If it is gasoline, it is spark plugs.
look on the very top of the motor and you will see a long rail them are the spark injectors for your spark plugs. pull them injectors out and you will see your spark plugs.
there are four spark plugs.
Fuel at the injectors or in the tank? If it is getting fuel to the cylinders, spark to the plugs and is in time, it has to run. Checked the plugs to see that they are not fouled? You can give it a shot of starter fluid and see if it fires. If it does, that means it's not getting fuel which means injectors, fuel pump, filter. computer, check the fuses under the hood.
make sure your getting fuel to the injectors make sure your getting spark to your spark plugs and wires or coil overs depending whats on the car
Plugs, coil, injectors, etcsee related question below.Plugs, coil, injectors, etcsee related question below.
Try the oxygen sensor and the coolant temperature sensor.
Usually it is a crank/no start, with either no signal to the coils or injectors. Check your fuses/relays first. If you have access to a scan tool would speed things up. Then just do the normal fuel pump are you getting pressure, spark at the plugs, noid light to check injector driver signal. Could be a cam/crank sensor.
on the motor
A four banger engine has four fuel injectors and four spark plugs.
