So i just bought these coil packs off of amazon, and decided to replace them before i head to work. Once i finished replacing them i tried to start up the car and it just shuts off. Its kinda weird because it sounds like more of a vacuum leak but i checked all the lines and everything, and everything is connected and nothing is out of place. Please can anyone help me. I mean from before it just vibrated a bit it was misfiring but now its just shutting off while sputtering.

Bad coils maybe?

Are you sure you not put a spark wire wrong? Or one of the connector on the coil is bad? No made a good contact? If you check the air lines, check the wires that go on the coils. Both wire touch and made missfire.

Again, check your wires coils. Also, can be one or all the spark plug wire going bad as well.

Hey mate, does it have any codes?
If not, see if the following can help -

• I would check the wiring of the 2pin connector to all three coils to make sure there's no shorting like "Mcon" said.
• Use a ohms meter to confirm that the resistance of the primary and secondary coils meets specs according to the supplier (which should be similar to oem specs).
• Use a spark tester with a big gap (10mm) to see if all lines are sparking. (do one at a time and unplug injector plugs while doing the test.)

Apart from those things, check your spark plugs, check for carbon tracking along the coils, HT leads.
If you have a scope, you can check the actual primary ignition waveform on all coils while cranking, this will show you that the igniter is trying to fire the coils and the coils are generating spark properly.

Really quick question I see gs300 spark wire sets online and it says that it comes with 3 but I know there's 6 spark plugs of course on a gs300 ,do I only need 3 spark plug wires or 6 spark plug wires , please help

you only need 3. 2jzge's are waste spark and you 1 ignition coil for two spark plugs resulting in 3 ignition coils and 3 wires

Very nice answer

it is a safety feature when a coil pack fails or is bad. The flow of gas is shut off after 2 seconds when a bad pak is detected.
