03 silverado new cks tps camsensor no spark to coils

Hello,

Assuming your spark plug firing order is correct after the coil pack replacement and your plugs and plug wires are clean and connected properly--and you have gas in the vehicle--I am thinking Throttle Position Sensor (TPS).
To test the TPS you hold the throttle pedal to the floor and start the vehicle, if the vehicle starts you need to clean or replace the TPS.

If the vehicle will still not start and everything was replaced on the vehicle as the parts came off of the vehicle--and the vehicle ran before think:
Compression: Washed cylinders (pull plugs and squirt clean oil in spark plug holes (one-two squirts).
Fuel: pull hose after fuel filter and crank vehicle
Spark: Pull plug wire and arc with screw driver when cranking engine. New coil pack could be faulty.

You may need someone to crank the vehicle (mind your hands) while you test. You should be able to find videos for spark testing.

I hope this helps.

the ecu may need rebooted or flashed call dealer ask for service dept and tell problem

have you or anybody at pep boys changed the igniter and coil. if not try to find a used igniter and coil to test with, they're pricy. If it works replace with new parts.

Have your coil checked.

Since you have replaced all of the parts, perhaps the problem is the wires. Check continuity of critical wires. Are you getting power to the computer, ignition module and coil? Check continuity of wires from computer to ignition module and crank sensor. Check for bent pins and pushed back female terminals in connectors.

I assume you mean it will not spark.
You would need to check the ignition module the coils are attached to for power and signals from the crank and cam sensors.
You may need a shop manual for the testing procedure.

Is this a 4 cyl or V6 ?
Are the coil or coils getting voltage from the key switch, and ground pulse from the computer ?

im having a sim issue guys.. my 95 auto. once it hits running temp it dies. checked at that temp no spark.. did the coil plugs wires dist.cap n rotor fpr purge sensor and egr sensor.

Put a code reader or scanner on it. Sounds like a Throttle Position Sensor or Bad Coil. The TPS is avail on line or at auto parts. You DO NOT have to replace the entire throttle body, if sensor fails. Coils are $51.00 or maybe less on line.

try the coil in the distribtor cap, most coils go out after a few years, has to be the coil since you already replace the module, im sure it will fix you up, thanks hope to help, thanks robert b.
