HELP!!! Gs won't start and has no spark!
 

Ok guys I need help ASAP because this cars my daily.
I was at bumper to bumper traffic and as I accelerated car did a hàlf second sputter. Instantly I thought she overheated. But the temp gauge was normal. She cranks all day but I pulls the wires and there's no spark. Here's what I already ruled out.

Check all the fuses and everything is fine.
I replaced the efi relay and it did the same thing.
My cousin has the same exact car so I swapped the igniter with him and still no spark.
I swapped the relay that says engine I think and still no spark. The fuse that says engine main is still fine. I checked only the front and rear coil packs because the middle one is blocked by the intake.(still would safely assume the middle coil is out also. Now as far as timing I checked briefly. The 2 cam gears were both still in the matching positions to each other so I assumed the timing was set right.

Can anyone help me with this? I need to get this sucker fixed now!

Check engine codes. Could be Crank sensor.

I had the same problem turned out to be the fuel pump, you can check by spraying carb cleaner in the intank and crank it to see if it starts.. hope this helps

Fuel pump still works I can hear it. There's clearly no spark. And I don't have a scanner. And I thought cam sensor and cps would only make it run like ****. But she should idle some.

I said CRANK sensor not cam sensor. Crank sensor controls when your plugs ignite.

I know your said "CRANK" sensor as I stated wouldnt the crank sensor just have the car fire like **** and it still would spark?

If the crank sensor is gone it will not fire at all. If the cam sensor was bad it will run like ****. Doesn't hurt to test though. My car did same thing. I had fuel, compression, proper timing but my spark was not consistent. result was my car wouldn't start and I had wet plugs. I basically changed everything you said you did and still nothing. when I changed the crank sensor it rolled over right away. I say pull the wire on it and do a Ohms test just to be sure.

I think you're thinking of the knock sensor.

So i scanned the car no codes and live data showed up fine. I'm going to get my key reprogrammed. If that doesn't work in going to swap out the cps and if that doesn't work it's only gotta be one thing the ecu....

I had this issue a while back. Turned out it was the key. If the key's not programmed to the car then it will crank but not start. Maybe the battery died on one of them? I'm not sure if a dead battery affects it, probably would though. I had 3 keys and 1 wasn't programmed so it would crank but the other 2 started it up just fine.
