so your car runs and drives fine etc after the swap... i know whats all involved with the swap with what parts i need etc but how does the car run etc.....
this might be a stupid question, but whats the difference between the 02, and the 03-05 ecos?

The fuel rail

What makes you think that it is the injectors? What is it doing? Have you checked fuel pressure? I would ask if you have checked your spark but that is tricky on the Eco. I had the same problem with my car a while back, was driving and it just died on me like it ran out of gas. Turns out it was the ignition. New IDI and cover and it was back on the road. You might wanna trouble shoot a little bit and make sure it is the injectors. It would suck to do the swap and your car still not run. Good luck and keep us updated.

John... i replaced my fuel pump a few weeks ago and just all of a sudden i got the multiple cyliner misfire light.. and the car was running on 2 cylinders well i replaced the spark plugs and boots and no go.. i replaced the coil packs and now the damn thing wont even start on the old packs or the new ones.... so i am replacing the icm next because i am getting fuel but someone told me that because i had to fix my return line on my pump it might be messed up. see i snaped the return line off the pump during install and took a wire crimp and pressed the metal out and used finger nail glue to gule it back together. someone told me that the gas ate that gule and cloged up 2 injectors but i talked to a buddy of mine thats a cemestry major and he said that nail glue is not like superglue and gas wont touch it.. so i dont know.. if te icm doesnt work i was considering doing this since the gm charger is on my to do list....
you need the whole rail and the injectors and the injector spacers I have the p/n at home somewhere
I have had problems after the swap, the car must warm up to 150 degrees before I can drive it without it stalling when I come to a stop
If you wanting the Gm charger your only option is to rip one off a cobalt motor, if your waiting for the kit good luck thats pretty much never happening
