No Spark on 1 & 4

[805eclipse]

Ok im stuck in my home town and i need to get back to school tomorrow but my car broke. here is whats happening, my car starts and barely runs it idles like crap and has no power at all i can barely get above 15 mph. i checked the spark and only cylinders 2 &3 have spark 1 & 4 have nothing. Occasionally i can get it to start randomly but the problem comes back and now it wont run right at all. Any ideas?

oh and the ecu was just replaced because of leaky capacitors. THANKS

check the plug for the coilpack. 1/4 are on the same coil. if the plug is okay then try tapping on the coil with a extension or somethign and see if it works. you may need a new coilpack

yeah i actually have another coil pack laying around from a parts car and i hooked it up but it had the same exact problem. any other ideas ill go check the plug and wires.

Update:

I have a CEL and checked it with my datalogger and it comes up with 44 ignition coil/ power transistor unit. so i think it is my PTU what do you guys think? and how do you test it?

Ya thats your problem they are going bad left and right. Not sure the test on it but just get a new one and problem solved.
