Turning over good but not starting after changing plugs

First check the air filter to make sure you didn't suck water into the filter.

might be that you accidentally disconnected the crank sensor close to the transmission, this gives a no start condition without a check engine light on most cars...

IF the motor is cranking, is it getting any fuel? When you turn your key on, do you hear the fuel pump kick on? Most cars today are fuel injected, and use an electric fuel pump. With another partner, have them stick their ear on the gas tank as you are turning the car on. You should hear some kind of pump, if not, your fuel pump may be dead.

double check the wires and make sure the firing order did not get mixed up. This can cause a no start, the vehicle will sound like it wants to go but just floods instead. Good Luck

First, charge your battery all the way, Is your check engine light on? How did you determine you have spark and fuel? Did you try starting fluid?

Hi Chris, From what you have explained I would suspect that you have a leakage where air is being drawn into the system. A good place to start looking is on the filter housings. Sometimes the gasket seals leak and give those symptoms. Once you have eliminated that area it would be a good idea to check the entire fuel line and even replace it. The glow plugs may be new, but what about the control circuit? Take a test light and make sure that power is actually arriving at the plugs? Lastly it may be the head and rotor, which is a part of the distributor type injector pump. Depending on the amount of sulpher in the fuel in your part of the world determines the life span of that part of the pump. As you say the pump has been serviced find out if the same unit was replaced. Good luck and best regards John

Check the starter relay.

No spark, ck the crank position sensor. bolted on engine at the front crank pully. Good luck. unplug and plug it back in to clean the wire connection/

change fuel filter . our your fuel pump might be weak and also the spark plugs may changed

If a defective spark plug was found, it can destroy the secondary winding in the coil pack for that plug. Change the plug wires too.
