I've got a problem /o/. My dad has had this firebird for 2 years and he is letting it rot in the grass and keeps procrastinating. I doubt he'll get it fixed so I want to. It cranks over but won't start. I've jumped the battery and use starter spray. Still won't crank over. Any ideas what would cause this?

Check fuel/air filters, spark plugs
What happens when you try to start it exactly? Sounds, vibrations, etc, be very specific.
>>14855348
Cranking like almost to start but never catches. Also backfires bad if using starter fluid
Check for spark
>>14855357
Sounds like fuel isn't getting to engine or spark plugs aren't firing.
>>14855380
Any specific way to do so?
If you haven't put fresh fuel through it and it has been sat for 2 years it aint gonna start
>>14855416
I siphoned the tank and put new stuff in

Random question. Would the security system cause it to not start?
>>14855480
No.
>>14855499
Alright thanks. I'll check all the plugs
>>14855506
And the air filter.
>>14855324
Run an OBD2 scanner and see what the check engine says. Buy a Bluetooth scanner off Amazon and buy the app it'll save you time and money I greatly recommend it.
>>14855534
Just take the air filter housing off and let unfiltered air into the engine. Should help you start it but you want to put the air filter back on soon after.
>>14855562
if its not starting it probably won't pop a code
>>14855324
you need 3 things for the car to start
spark
fuel
compression
check for spark then check if fuel is getting to the cylinders
and then for compression you'll find your problem in there
Check the schrader valve int he engine with the key in the run position. You should have fuel coming out.
If no fuel comes out, congratulations your fuel pump isn't working.
>>14855480
No, if it was the security system it wouldn't crank at all. I've dealt with the VATS bullshit before.
>>14855534
>>14855590
No, no that won't help anything. You're a special kind of stupid aren't you?
This is an Optispark engine, right? God help you.
Go to Harbor Freight and get a fuel pressure tester and a compression tester. They are about $20 each. Could be a bad fuel pump (just changed one, you have to cut a hole in the floor of the trunk to get to it).
>>14856715
It's a 3.4 V6, do you not know your fucking 4th gen body styles?
>>14856644
>not getting any airflow won't help anything
Come the fuck on, it's like 30 seconds to make sure the filter doesn't look like it came out of a coal bunker.
>>14856636
Could be a possibility. Considering I have to crank it with pliers. I'll show pics in a bit
>>14855324
GM cranks but no-start? Fuel pump.
>>14855324
sounds like the cranker is fine but the starter is gone
I got this to deal with too so

you know why your dad left that Thunderbird to rust?

>>14859085
I seriously can't tell if this is bait or not.
>>14859085
Thunderbird?
You mean like the show with the marionettes?
Everyrhing has been covered in this thread except one thing.
STOP spraying starter fluid in a fuel injected vehicle!
There is no where for the excess pressure to go and it will go boom. Ive seen it happen and your asking for a nasty fire.
Also I recommend you change the fuel filter. Cheap and easy and could be your problem.

i was on the fence but this is definitely bait
>4/10 made me reply
If it gets fuel, spark, and air, try checking if the temperature feeler is ded. Might be reading as if the engine is warm, and then giving you less fuel and more air, making it not wanting to crank.
>>14859115
>what are valves
>>14858982
>VATS
>That's the *other* GM problem.
If the car fires for like half a second and then stalls and a Security light is on in the dash you've got a VATS problem. The most common failures are the lock cylinder contacts not actually making contact with the key (new lock cylinder) or the wires that connect the lock cylinder break internally. You'll need a diagnostic flow chart to know how to test for where the failure is. I can't image somebody hasn't uploaded it by this time so it should be on the intertubes somewhere. Happy searching Anon!

The only real way to tell is wheels and if it's a firebird or a formula/trans am.

No you don't, you filthy ape. The correct way is to drop the tank.
