hks fcd problem,car wont start,run properly

[Mikey4410]

its getting progressively worse

 

[MARK@CMBAUTOS]

iv seen folk mix up the 2 wires going to the map and fcd and it gives u all the symptoms ur getting

as in swapping the white and yellow ones round
also whats it set to while ur installing it ? if u set it to 12 that should the factory settings as if it wasnt installed

 

[triple j]

plug it out man, and see if u still have any problems.

 

[Mikey4410]

its not in .took it out the other nitght when it didnt work

 

[triple j]

check your plugs and leads, what pump did u put in to it.

 

[Mikey4410]

a second hand "uprated one "

 

[triple j]

get it out, try your old one in if it not fucked, chances are that second hand one is fucked.

Check you have 12 volts on the red and black, then check you have not dislodged the pin to the ecu in the ecu plug. Sometimes when searching and stripping the wire back it can be pulled back into the plug a little to much and cause a bad connection.

 

[Mikey4410]

original pumps back in now and i even left the battery plus of for 5 mins and put back on.

the car doesnt rev up barely at all now and its undriveable.........

i just dont get whats goin on. somebody please help

got to cycle 10 miles to work now each day.

the car drives like when a few years ago on my other starlet i blew the dashboard electrics which i believe is inline with the map or maf sensor.

it coughed and farted and didnt go anywere with the hint of throttle ?

 

[weeJohn]

Check all the connections you were at, then remove the map sensor plug and see if it gets any better.

Is the check engine light on? Has the ECU stored code 31 or any other codes for that matter?

Can you get a video clip of the engine running, it would get you a little more assistance.

If your not sure how to upload a video via youtube, photobucket etc... email it to me at texx@toyotagtturbo.com

just tryed wiggling the wiring and checked the plugs and all looks ok

the car just about ticks over but sounds like a subaru,definatley sounds like its a cylinder down ??

 

[Mikey4410]

i just removed the plug from : sensor assy,turbo pressure,and the car stopped.
undid the other unit in the left corner of engine bay if looking at car and that didnt do anything(has to vacuum pipes going in)

i will do a video but i have a poo phone so dont expect to much.

With the engine idling, pull the spark plug leads off one at a time (if you've got some thick rubber gloves, put them on). If you pull a lead off and there is no change in how the engine runs, then you've identified a cylinder that's in trouble.

sounds exactly like you got map sensor wires wrong way around, or disconnected.

 

[Mikey4410]

i have a 31 error code !!!!!!!!!!!!!!!!!

You've just disconnected the MAP sensor when the engine was running, so that's not surprising. Now reset the ECU (remove the battery negative terminal or the 15amp EFI fuse for 30 seconds), run the engine for approx 30 seconds giving it a few revs and then check for codes again.

im thinking the fcd killed it ?

its only played up since wiring in the fcd (from what i know 100% correct as i have checked over and over)

That's unlikely, more likely to be a wiring issue if it's not something unrelated.
