Average failure mileage is 27,000 miles. A weak coil or bad coil wire, a bad pick up coil or crank sensor or a bad rotor can all cause a change in the spark. The starter voltage drop should be less than.5v drop total on cranking circuit.
If you see smoke, stop cranking! The problem you are experiencing with the no start/extended crank time is likely due to low fuel pressure. No, it isn't an ignition issue.
Then the throttle position sensor ( tps ) had to be replaced. I have no idea where to start looking in the electrical system for the issue. Check power to the starter motor solenoid.
Owners of these vehicles may comment that the engine starter will continue to run after key is released. Ran the same tests with the key turned to on, 11.8v In this video i take you through a bit of the diagnosing this 2006 chevy 1500 truck that was towed in with a no start no crank condition.

Chevrolet recommends waiting 15 seconds in between each attempt at starting the vehicle and not cranking it for more than 15 seconds per attempt, to prevent draining the battery or burning up the starter. When your engine is not cranking (turning) over it will be mainly due to three separate areas, first it could be the battery, cables or poor connection, next is the starter. ( 296k miles ) i had a pressure reg failure and replaced it.
It ranges from a simple lack of fuel to an empty battery to a broken starter. However, there is a wide range of possible reasons why a chevy silverado 1500 does not start. Tested all the voltage from the terminals, to the battery cables, tested the grounds, master fuse, starter, while off.
Low fuel pressure will make it hard to start a cold engine. It cranks, but won't start. You need to find the reason voltage is getting to the starter at the wrong time.
When the ignition switch is held in the start position for 0.4 seconds, the pcm/ecm start timer is activated. Its been through some puddles lately and. Defects in the electrical system, the fuel pump or the ignition lock can also paralyze a vehicle.
2003 5.3 flex long cranking before start i have an 03, flex fuel 5.3. This is an important step and is often the cause of a slow cranking complaint. The truck has an immobilizer but still cranks without the fob in the run position.

My 2008 silverado won't start battery is charged. If the starter is spinning and cranking the engine, the starter is probably ok. It acts just like i released the key too soon.
Before i sink a boat load of money into this thing at the dealership, any idea? It can burn up, or the wiring associated with it can burn up. This is a normal condition and no repairs should be attempted.” ha!!
Go to start it the next day and it starts with the key in the run position, (good thing my foot was on the clutch.) the starter keeps on cranking after it is running. You’ll want to take a look at your silverado’s battery cables and battery posts.
