No spark on cylinder 1 and 4

[justinhill]

Like the tittle says, put in a new coil new power thing next to the coil, has new crank sensor car starts and runs on 2 and 3. any input what it is? Could it be a bad CAS?

ECU maybe or cas

I had the same problem. I forgot to install my cam postioning sensor. See the cam sensor runs one pack and the crank sensor runs the other pack. Looking at the motor if you left pack is doing nothing but the right one is then its your cam sensor. if the right one does nothing but the left one does then its the crank sensor. Least thats what it was on mine.
if it is your cam sensor make sure that you remembered to install it and plug it in. If you forgot to install it you can put it in without taking your belt off but you have to be very carefull and loosen the cam sprocket and pull it off just enough to stick the sensor in there. Its hard to do but I managed to get it done so I know you can do it.

^^^ Quoted right from talk^^^

You need to find a working cas

New CAS,switch coils,switch power transistor still no spark.

I was going to say the power transistor.

Swap the wires from 1-4 to 2-3 and see if the problem follows the switch.

update: I pulled the plugs on 1 and 4 and i'm not getting gas to 1 and 4. Is there a certain way the Crank sensor suppose to go in? and the cam sensor? when I replace the cam sensor I lined the timing up and the little paint mark with the sensor, was i suppose to line the crank sensor up with the timing on mark also could that cause no spark in 1 and 4?

how does my ecu look? http://i56.tinypic.com/2qxp91v.jpg

Ok, I got this narrowed down... I went through the whole harness patching/replacing wires,New crank sensor,Changed out CAS,Changed out Coil packs,Changed out power transistor,new wires and plugs . All I need is someone that can test my ecu in there running car to see if thats the problem also would a bad injector resistor pack cause to no fuel and spark to 1 and 4? I been going at this for the last 8 days for at least 8-10 hours a day this is getting stressful...:jerikoporn:

bring ur ecu up to my place and I can see if it works. Ill be around tomorrow so text me if that works. 651-269-2314
