I hope someone has an answer for me. My Jetta started running a bit rough, especially at start up. I assumed it was the coil, all signs pointed to that. So I replaced it. Didnt really help. So I went to start it to leave work and it wont start at all. Cranks just fine, just wont fire. So after getting it scanned it gives me code P0321, all signs pointing to the engine speed sensor. So I replaced that as well and looked for bad connections. Still won't fire. I have checked the fuel relay, and all fuses. Any ideas what else could cause this? Maybe fuel pump? Frustrating.
