The starter continuing to crank is normal on this model. The starter circuit is computer controlled. The problem is that it fails to start. Knowing these models the first place I would look is fuel pressure. They need 55psi minimum to start. If pressure is ok after that check for spark.

You may have a problem with your ignition switch having an open circuit. The switch and/or lock cylinder may be sensing that the key has remained turned to the start position. I would lean more toward the ignition switch having an open circuit, but you should get this diagnosed. Alot of the 2002+ GM models are having ignition lock cylinder, ignition switch, and passkey sensor problems right now.

The starter solenoid switch contacts get burned and welded together due to the 150 Amps of current that flow through them, just like an arc welder welds metal together. If the solenoid is an integral part of the starter motor as it is on most cars nowadays, you'll need to replace your complete starter motor assembly soon. Be prepared to pull your negative black battery cable off the battery at any time by loosening the connector bolt in advance of an emergency in which the starter motor keeps running and won't stop until it runs the battery down.

The ignition switch it's self is actually on the steering column above the brake pedal.
The key assembly is actually just a locking mechanism that pushes a long rod that is the length of the steering column down to the slide switch.
If when you turn the key to the "start" position does it seem fairly difficult? Like it's binding on something?
If, when you let go of the key, does it remain in the "start" position briefly?
If the answer to the above questions is no, then you need to replace your starter.
If the answer is "YES" to any of the questions, you could have a bad key lock assembly, bent ignition rod along the steering column, or a broken or dirty return spring in the switch.

i might like to commend you on desirous to get in spite of have been given the top gasket (suspected) to be blown fixed to boot. in the beginning in case you are trying this interest your self, i might take the top to a gadget save and ensure it became no longer cracked or warped (extremely if its aluminum which i think). Then, get the crankcase flushed out, alongside with the comprehensive cooling equipment. oftentimes a head gasket might blow by way of 3 form of an overheating situation. a pair of low-priced yet considered necessary areas i might advise changing could be the thermostat and the radiator cap (by using the years the cap won't be able to hold stress, ensuing in a loss of coolant and/or overheating). additionally verify if coolant had gotten into the crankcase. if so, that's extremely useful to think of on the subject of the oil pump.

Your Starter SELNOID needs replaced. When they get to hot the contacts melt. Replace as soon as possible or it may burn out some of your ignition wiring if it sticks too long,

one of your problems is the starter spring[ abendics] is sticking, this is why it continues to turn over once you remove
your hand from the key,this may also be the reason it doesnt start..
