Your idiot lights should have one inclusive of it. There is a single wire check connector by the leading coil. That wire when grounded to the negative terminal of the battery and w/key to on the Check Engine light of the idiot lights will provide you w/flashing codes if there is a trouble code to be had.

well when i first put my battery back in and tried it there wasnt any codes at all. So i wanted to see what it would look like so i unhooked my AFM and it went something like this. 1(long one) a pause then 8 short ones, so would that be my Ignition Coil - Trailing Side And my AFM?, i left my battery unhooked and then ima hook my afm back up and try it again see what happens

ok so lets re-cap on what has been accomplished here

Fuel Pump, Filter, Lines replaced
Oil Lines replaced
New Spark Plugs
New Clutch (i know has noting to do with the car running)
New Vacuum lines (3.5mm I.D)
All Actuators have been serviced cleaned and working properly
ECU pins have been Continuity Tested-Everything Working properly
Trouble Code Testing- No codes- Working Correct
Ohm out the AFM- Everything within Spec according to FSM
Sanded Down and Re-grounded my Ground wires

Im starting to run out of ideas, i think this thing has to be outta time

Code 18 would be the TPS. Codes should be definitely thrown if a sensor is disconnected so you might want to disconnect a couple of items or so on the list and check for codes to see if any are thrown or not to see if this aspect of the ECU is working or not.

sorry for the HUGE pictures in this im still trying to figure it out, but anyways i was reading the forum about timing and it says that the pulleys differ from S4 to S5 i might have the wrong damn pulley on it, is there anyway to tell them apart

no i haven't had time to mess with it yet, ill probably do it Friday or if i wake up early enough one day this week, its just super aggravating because it will fire up and you can put your foot on the gas and it will rev up, but once i let off it just dies. but sometimes it will idle perfectly if i unplug the AFM. so ill re-time this thing about 3 more times then if it doesn't work I'm out of options
