05' tC, 98k Miles, Dezod S1 Turbo, etc.

It has a CEL light on with P0335B and P0340.

Replaced the Camshaft Position Sensor, and ordered the Crankshaft one. Just replaced the fuel pump with a Walbro High Flow one. Not sure exactly which relay/fuse is for the fuel pump so I just tried moving the Horn relay around a bit. Also tried resetting the AEM Piggyback (Disconnect battery for 10minutes.) Car still won't start.

The car will start up most of the time with some starter fluid, but will die if you try to drive it.

Anyone have any ideas if the Crankshaft Position Sensor doesn't fix it? (Will know in in a few days.)

EDIT: Took the AEM F/IC out and plugged into the stock computer. Car still start, rev to 3000, and die.

Should I try to get ahold of AEM and get the F/IC looked at or should I try to change the Crankshaft Position Sensor first?

Who made your harness? I'm 110% convinced it's wiring.

EDIT: If you bypassed the FIC, it's obviously the wiring harness. I'm going to guess it's a boomslang harness?

Do you have the resistors in your harness?

RJSCION · 08-18-2012, 11:55 PM

I was going to reccomend the resitor idea, but I wasn't certain anymore about that. I know when I installed my harness, we had to REMOVE the resistors for it to work. But I can't speak for TCs.

95% sure it's a boomslang harness (just got the car a few weeks ago, first turbo'd vehicle so getting used to all this kind of stuff.)

The guy I got the car from said that he had the resistors in but to check them to make sure they didn't go bad or something like that. Like I said above, first turbo'd vehicle so I've never dealt with anything like this. Always been a 4x4 guy.

Mind elaborating on how to put resistors in/check them/replace them/whatever.

Sorry for not really having a clue as to what I'm doing, or what I'm really talking about. We all gotta start somewhere

Anyone else have any input?

Still won't start

sebbyxtc · 08-21-2012, 03:01 AM

Call dezod

Dezod or AEM?

Start with Dezod, they might be able to point you in the right direction

AEM keeps having me leave messages, and Dezod told me to check a few things and tried to help but couldn't do much for me over the phone.

Still looking for solutions. Anyone think maybe the AEM just ____ out on me? Should I try to get the plug and play replaced by AEM or do you think I should just throw in the towel and take it to a shop (prefer not to with my funds.)

sebbyxtc · 08-22-2012, 03:54 AM

send the fic to aem for troubleshooting, maybe the map sensor crapped out. what did dezod tell you?

Dezod told me to pretty much check all the vaccum lines, etc.

Perplex · 08-23-2012, 06:23 AM

Today I disconnected the battery for about two hours and then reconnected and let the car sit while I went to work. About 8 hours later I came home and was going to vaccum it before having it towed (so when I got it back I wouldn't have to.) I decided to give it a shot and start it up - and it started with the AEM F/IC.

I drove it around for awhile and it seemed fine except it couldn't idle. Anytime I went to a red light I'd just give it a bit of gas and have the car rock rather than let it attempt to idle and have it die out in the middle of my town. I went and washed it, and then went to restart it and it took 2-3 cranks but it eventually fired back up.

However, it used to idle at around 700-750rpm and it's now idling (rough) at anywhere from 300-500, usually sitting around 450-500. It sometimes dies, and will sometimes idle at that RPM. Could this be the AEM F/IC just ____ting out?
