Chevrolet K1500 No spark,random misfire

Fault noticed on Chevy silverado, No spark and random misfire.
Distributor and timing chain replaced.
Coil is absolutely new.

On such case i suggest test the basics:-----



Suppose if you remove the distributor cap and turn the engine.
does the rotor turn?
is this why you got the new distributor?or ,did it run with this distributor?
Do you have a spark on the coil wire from the coil?

TEST THIS POSSIBILITIES FIRST:


When the distributor is faulty,many a times you get error codes related to faulty cam shaft sensor and crank shaft sensor


If there is no spark out of the coil... then i suggest problem is with ignition module.
For exact location of ignition module check the link below:-----

Ignition module located on ChevySilverado K1500

The red wire to the coil,,,it should have battery voltage with the key on.That is 12 volt.
If not, then the problem may be the with ignition switch..check that,,if so,,lets check that new coil.

For how to check ignition coil on your vehicle i suggest the following link

IGNITION COIL TEST

These details will help.

Thanks.

Air Injection Reactor Pipe on Car?

If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.


Air Injection Reactor Pipe with the aid of the air injection pump (smog pump), injects air directly into the cylinder head or exhaust manifold at each exhaust valve port. The air helps to heat the exhaust gases and burn off toxic gases as they escape from the engine cylinder as the exhaust valve opens.

Air Pump Check Valve on Car?

If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.


Air Pump Check Valve is a one-way valve that lets air flow from the air pump to the exhaust system. It's usually located in-line between the diverter valve and the air injection reactor (AIR) pipes in the cylinder head/exhaust manifold ports. It keeps exhaust gases from entering the air injection system.

Air Cleaner Temperature Sensor in Car?

If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.


Air Cleaner Temperature Sensor, Measures air and fuel mixture in the intake manifold. The engine control computer receives the signal from the sensor and adjusts the injector pulse width and fuel mixture. It senses the temperature of incoming fresh air and decreases the vacuum when the air is warm. When the air is cold, the sensor directs more vacuum to the air cleaner vacuum motor.

You can buy this part from Autozone service centers.
