2003 Jetta 1.8t AWP - 140k had an APR 93 since 40k.
The only code I've had lately (and consistently) is the coolant temp sensor.
It's been very cold and it's been pretty rough starting lately. (and usually when it's cold I need to keep the RPMs up for a bit if it hasn't been started, to prevent it from choking/dying) I tried to start it last night, and the battery started to die. So, I charged it up, left it connected to another vehicle and it would just crank and not start.
Anyway, today I didn't hear the pump starting every time I opened the door, but verified the pump is working by taking the hose off at the rail to make sure it is getting fuel. Next, I took the coil pack out along with the spark plug, and dried off the spark plug. We left it out, grounding it to the valve cover, and tried to start it to see if it sparked, but no spark!
Could just a faulty coolant temp sense prevent it from starting? Could it be some of the other culprits, such as a engine speed sensor, even though there is no code? Wouldn't something causing the plugs not to fire have caused a code? Are there any tests I can do with my Vag-Com?
I've done quite a bit of reading/searching and am out of ideas... any idea how to troubleshoot this? I would think if the coilpacks or plugs were dying, i would have had at least one little misfire here or there, but haven't.
Thanks!
