Nick, I would start with the easiest things first and do a simple elimination until you figure out exactly why it won't start. #1 Spark plugs. #2 Spark plug wires. #3 ignition coils.#4 air/fuel filter. #5 Fuel injectors. #6 Fuel pump. #7 Electronic control module(ECM)/computer. If these things I have stated are replaced with new, then there is no reason it shouldn't start. I gave you this list as easiest to hardest to replace. You may find that the problem is only with the spark plugs, then obviously you have detected the issue and do not need to continue replacing components. I hope this helps, and good luck. ^^
Well, there are several basics your engine needs to start: Spark, fuel, compression, and correct valve timing. I am going to assume on good faith that your GT has the 3.4 liter V6. Here are a couple basics on checking fuel and spark: GM usually puts a schraeder valve (looks like a tire air valve) on the fuel rail. This is where you connect a fuel pressure gauge to test the fuel pressure. It should be 52-59 PSI when you turn the key to run. If your fuel pressure is good, remove a spark plug wire from one of the front 3 spark plugs. If you have a spark tester, connect it to the removed plug wire. If you don't have a spark tester, remove the spark plug. Plug the removed spark plug or tester into the plug wire. Touch the metal threads of the plug or tester to a good solid metal part of the engine using gloves or non-conducting (plastic) pliers. Have someone try to start the engine. Watch the gap at the end of the spark plug. You should see a bright blue/white spark and hear it snap every time it fires. If you don't, there may not be any spark getting to the engine. Diagnosis of the problem can be far trickier from here on out. You will need to be able to diagnose electrical problems in the fuel/ignition system to find the root cause of no fuel/no spark.
If you cannot hear the fuel pump run in the tank when you turn the key to run, try lightly rapping the bottom of the fuel tank with a hammer turned to its side (don't put a hole in your fuel tank!) while someone cranks the engine over. If the engine starts, most likely cause is a failed fuel pump. Don't expect the car to keep starting on a regular basis if it does start by hitting the tank. The fuel pump will need to be replaced.
pull one plug wire insert screw driver intothe spark plug boot getthe screw driver 1/4 inch away from a good ground and where it won't move. crank engine over if yo see a blue spark then you have another problem if it does nor spark yo have a bad coil or contact set.
There are two things to check. 1.It is producing a spark. 2.It is getting petrol through.
To check whether isproducing a spark.
Remove one spark plug from engine. Reconnect HT lead and hold it touching car chassis and turn the engine. Do no hold the Ht lead with bare hands while doing this as it carries thousand of volts and will give you nasty shock. Hold it with some insulted material .
When you turn the engine you see spark across the plug electrodes.
As for fuel,trace the fuel pipe coming into the carbureter and disconnect pipe and have someone turn engine .Petrol should gush out showing that the petrol pump is working.
try taking the air cleaner assembly off you might not be getting enough air to engine
if this is the case then the throttle body needs to be maintenanced
heres another suggestion it just hasnt sucked gas to the engine to crank over sometimes they help
go out buy an electric fuel pump
find the fuel inlet source to engine hook up electric fuel pump
attach only ground to something in engine compartment
then get a can so that when gas comes out it has something to go into
tap the electric fuel pump power lead to the positive of battery let run till gas comes out make sure not to spark your working with gas
once gas becomes present detach electric fuel pump all the way set aside
hook gas line back to port and then start vehicle this should start
also with fuel filters there are 3 on a vehicle
one in engine compartment
one on chassis back by the tank
and one in the tank called the sending unit this has a filter in the tank this one could be clogged
make sure these filters are in the right position with gas flow flowing in right direction
make sure fuel is going to engine from injectors, you can try by adding carburetor cleaner to intake and crak it, if it runs for a little be then ijectors are not firing, some times the ignition module to control the spark will keep the injectors from firing
