Oh BTW, if you hook up 1E via a low voltage/wattage ignition switched LED (the ECU pin 1E is the switched ground) you will have yourself a functioning MIL (Malfunction indicator Lamp)

this is doing my head in now.

i CANT get it working, damn it, i have probably blown something by now, i ****ing hate this car.

Are you still having problems??? Have you got it to turn over yet???

FD3SNuttah · March 31, 2006, 09:04:27 PM

frustrated earlier sorry!

sometimes when things dont go how i expect them to and i have absolutley no clue how to resolve it when it doesnt work and no one to help me out i get ****ed off!

I did get it to turn over (in a fashion) i crossed the starter and it was turning the engine just fine,. however it wont kick the starter when i turn the key to the cranking position.

i *think* that the problem may lie with a couple of the connections may be wrong and the fact that an auto inherently cant be started unless in park / neutral. this means that i have to figure out which pin it is and cross/ jump it so that this "feature" is removed. but i cant even find the right plug / wires off the tranny / body harness. the two are different as well the single pin connection on the starter motor on the S4 comes off the wiring loom from the gearbox, where as on the S5 its in the body harness. so i cut the plug off the auto box and then plugged it into the body harness and then to the starter and still no joy. :2Mad

im looking at the FSM and its all going blurry.

ok i been studying pretty hard, and it must be the inhibitor switch! im going to by pass it and run a new cable from the starter relay, problem is i dont know where that would be anyone got an idea where it is located? the FSM isnt very clear on this.

stuart wizy · April 01, 2006, 10:15:52 PM

did the starter kick over before you did the engine swap, ive got 2 fc starters here if you wanna try another one, if it turns out to be the switch over device on the starter.
are you getting voltage to small wire on starter when key is turned to cranking pos?

stuart wizy · April 01, 2006, 10:23:05 PM

sorry im not reading all of your posts, just read the difference between s4 and s5 wiring and for an auto, sounds like a real head scratcher this one.
like you say, take a feed of the ignition barrel for cranking, straight to starter small wire to engage starter.

FD3SNuttah · April 02, 2006, 12:14:48 AM

ta for the response any help i can get is appreciated. i will have another go at it tomorrow.

FD3SNuttah · April 02, 2006, 03:17:50 PM

well i have got it cranking off the key now! waheyyyyy! :cool

however its not going to fire just yet until i rewire my fuel pump relay. thats the next task. :Yawn this car is taking AGES to sort out, but i can see the light at the end of the tunnel.

so heres the task list left

rewire fuel pump / and relay.
wire up reverse switch
fit heat shielding under g/b
fit exhaust this might be a pain as i have to drill out some rusty bolts and weld new ones on.
remove rear spoiler.
replace rear lights for s5 ones
final checks (fluids)
and then hopefully waaaaaaaaaaaaaaaaaaaaaaa tsh. :WaveBye to the MOT station!
respray front s5 bumper and T2 skirts then fit them
refurb those rims and fit tyres.
get to rotorstock without breaking down!

good work mate, the beauty is when you do a project like youve done, you get to know the car like the back of your hand, fault finding becomes easy because you can relate most faults to things youve done and changed.
it will all be worth it in the end mate, theres no better feeling than driving the car knowing you did all the work yourself :WaveBye

FD3SNuttah · April 02, 2006, 04:04:06 PM

hell yeh!! im getting to know this car rather too intimatly (might start having to call it me missus!) i have never driven an Rx7 before (well up and down my road doesnt really count) so im looking forward to hitting the cruise when its all up and running,

i still havent found the relay!!

haha. instead i have decided to take a feed from the off the pin on the ECU. which isnt a good thing but at least i know i have got the iggy wires in the right place!

im hopefully waiting for someone to tell me where this damn relay is cos in the fsm diagram im not sure if its inside the cabin or in the engine bay!!

antnicuk · April 02, 2006, 04:12:08 PM

i think its in the nose cone at the front

Is the S5 engine from a manual car?, Reason i ask is that if its auto it wont have a pilot bearing in the end of the eccentric shaft.

The wire on the clutch pedal may be for cruise copntrol as when you dip the clutch the cruise switches off.

Stick with it, it sounds like a good project

FD3SNuttah · April 02, 2006, 06:07:23 PM

yeh the s5 engine and box are out of a manual coupe. the cab used to be an auto but i have added an extra pedal now lol.

there are a few relays there! but im sure they arnt the right ones because the FSM points to something near the firewall area. there is a little metal box behind the coil nearest to the firewall, but the wires dont correspond so im stumped. i cant see anything behind the dash area.

antnicuk · April 02, 2006, 10:50:35 PM

Ah, i was thinking of my FD, the fuel pump relay is under the dash by the steering column. sorry about that.

FD3SNuttah · April 08, 2006, 04:16:08 PM

quick update got all the bits needed for the fuel pump rewire. 40 amp 12 v automotive relay and some fuse holders. i need to go and buy some wire now.
