Car Wont Idle, DEAD

[xxShaneOmac]

Well Last night my mom left my lights on all night,
Woke up car dead, wont even turn over just Click.
Ok I get a jump, And the car Starts and runs the idle drops the engine rocks back and forth and dies,
I cant keep it alive for more then like 30 seconds, I will floor the gas I will feather it, I wont touch it. Nothing.

Fuel presure is pretty nomral. I have Gas Everything is off when I try.

I have a Check Engine light that comes on, But my DsmLink wont connect though my labtop to tell me what it is.

Any suggestions,
New bat? Fuel backing up?
I dont know .
help if you can thanks.

Try charging your battery first. If the alternator isn't able to deliver enough voltage to charge the battery and power the ECU, the low ECU voltage causes strange things to happen. If the car jump starts fine, I'd suspect the battery/alternator.

Also, it sounds like it could also be the CAS. There is a housing on the pass. side of the intake cam with a black sensor and plug coming out the back. Try unplugging it, blowing into it and plugging it back in and making sure it's snug. If that fixes the problem, you need a new camshaft position sensor ($80 - I just got one).

Also, you could try reading the code while someone is jumping the car. My guess is that the ECU isn't getting enough juice.

Ok ill throw a charger on the bat,
see what that does.

The car didnt start for a while when i jumped it.
but after waiting like 10 mins it then started but died quickly each time raised a little in idle time. but right now i cant get it past like 30 seconds before it dies.

Ill check that CAS too.

Btw I cant get my dsmlink to hook up to it at all. wont connect
I change back to stock ECU and now the car only cranks wont start.

Stumped

Ok, This morning got in the car, Would just crank and crank. Wouldnt start.
So I get a Jump and it still wont start, I have the other car gas it and my car starts, but is real ruff. And my car dies as soon as i let off the gas from the 2nd car.

So I go and buy a new battery. Car Starts with 95 Eprom DSMLink ECU. But idle surges to a point where it chokes and dies down low in the rpm range.

I change to the stock ecu, Wont even Start now.

Where to next.

Altho with the new bat, CEL is gone.

Old thread but curious as to what ended up fixing this?

I am getting a P0340 with the same conditions sometimes. I found an Airtex CAS for 45.79 plus shipping at RockAuto.com

Badass, you may have just scored me a 6bolt Sypder GST for $4000-4500 because it won't idle/run. Even if it doesnt do either at this price a new engine would still make this worth it.
