Thread: Pulled DIC and now car won't start

Thanks - just disconnect the air filter and spray carb cleaner in the throttle body? Or other recommendations to clean throttle body?

Subway guy thanks! I pulled the throttle body off, it definetely had carbon build up but I don't see how that would cause it not to start.. Anyways I cleaned it very very good...Looks brand new.. Then I took the IAC off (was a Autozone duralast) and the penile was extended all the way out - the spring looked stretched - didn't look in good shape. So since AutoZone has lifetime warranty I just replaced it. Put it all back together and fired it up - started right up - very very smoooth.. so thanks!

Now I just need to figure out why my 3 bulbs on the DIC aren't working. I ohm'd them out and they are ok.. I switched them to the two on the trac and they work.. so I will put some fly wires on the V rails and see what I got.. I'm thinking a CAP may have went bad that supplies the rails.. If this is the case I have no schematic so I will just get another DIC.. I did shine light against the display and I can see the computer is working just fine.. just the bulbs are not on.. Hopefully it's just the socket wings on the bulb not making contact.. Some fly wires and readings will tell for sure..

Again - thanks - strange the IAC and/or dirty throttle body would happen at the same time I am working in the DIC.. 267,000 orginal owners miles and now onwards to 300,000!
