FTO wont start

[Connor_1994]

lol,
my car has fuel,,
not much, but still does,

guess its a wire problem, probly have a coroded crank sensor or something i guess,

[PHIL069]

Your crank sensor was replaced, it would have already been on the half cut engine

those tiny little silver cylinder type things that have a you shaped bracket that bolt on, do they have to be bolted on to eart out?
cause the one near my throttle body isnt, but the other one never used to be either

You mean this...

[Connor_1994]

yeah i mkean that,

that one in particular isnt bolted on,
the other lower one is though,

and i mean my crack wire, theone that goes from my plug to my ecu, that may be corroded
also, my damn oil light is on
atleast now i know my fuel light works haha, when its on the damn E with only 5 litres in the tank haha

[payaya]

Your oil light will stay on until the engine is started!

Don't worry about everything else, check to see if you are getting spark and sufficient fuel pressure.

How are you testing for spark and pressure?

Check your fuses!!!

[Connor_1994]

my oil light has never been on until it flooded,
the engine goes out after it has started yes, but the oil light has never been on,

not sure on how to check fuel pressure :/

spark plugs are easy, hold the thread of the plug on metal of the car and turn over,
just watch for back fire if you do it near the spark chamber
(mate lit half his head on fire last time, -.- idiot
haha

I helped Connor tonight over the phone for about 6 hours trying to get his engine started, now I'm stumped and need help to help him.
Engine is turning over, there is no spark from the plugs, the plugs are getting wet with fuel.
We tested, as per workshop manual......
1. swaped out control relay
2. all coil pack intake wires from ECU = 1.5V fluctuating while engine turns over
3. all coil packs resistance test = 18 k ohms
4. all coil packs primary coil and power transistor continuity check = current flowing - continuity of 580 (closed circuit)/ no current flow - no continuity (open circuit)
5. ignition falure sensor check = 0.1 ohms
6. swapped out coil packs
7. swapped out spark plugs
8. swapped out coil pack circuit capacitor
9. engine light turns off after 5 seconds with ignition on
10. fuel drained out of tank and replaced with new
11. coil packs removed, spark plugs attatched and earthed, turn engine over = no spark visual from plug
12. no MUTII to use, manual code reading not working, we followed instructions for earthing out pin but no response
13. fuel is pumping out of the pump and the fuel filter
14. all sensors are plugged in
Ignition system tests all good but still no spark, WHY?
Engine is from half cut and was pre tested ok

Faulty ecu? I have a spare

[PHIL069]

Both ECU's, from original car and from half cut tried, and we are getting a current from ecu to coils.
Is it far for you to go to him with ecu for a test install

[payaya]

Look at your cam/cranks sensors. No signal means no spark.


Is it making a choosing type noise when starter engaged?? If so check the timing belt out.

yea its a good 1 ish -2 hr or more drive

Thanks payaya,
No noises coming from timing belt, checked through the oil fill cap and the cams are turning.
Might have to swap over cam/crank sensors tonight

[Connor_1994]

how are we gonna do that Phil?

ive had another look through the manual and wiring diagram this morning, havnt found anything we havnt already tried :/

[silverGPX]

So you have power at the coils but no spark?

Odd.

[Connor_1994]

tell me about it :/

[PHIL069]

how are we gonna do that Phil? PRAY TO THE FTO GODS

I will have a look at the book again myself, if we can't get it started by the end of the weekend you might have to get a mechanic or auto electrician to come over for a look.
Did you like the rundown post of last nights attempts? I was hoping others might have some ideas

P.S. My ears and throat were sore after 6 hours on the phone and I didn't have a dream last night telling me how to fix it

Dam you fellas have covered some ground getting to this point already, well done.... I dunno If I can help out all that much but I'd apply some basic logic (make it real simple for me because that's the way it needs to be so I understand it)

No spark.....

Okay if I am reading this correctly.....
All those crap sensor give that ECU thingie what ever is required too fire,
So X voltage should come out of 10,11 & 23 (not sure what x voltage is, it could either be a 3.3vdc or 5vdc (standard logic)
Trying to apply a little logic... an NPN transistor, for current to pass from the collector to emitter there should be a small voltage applied to the base. Logic suggests you should see a small voltage here.

Either way and a point I would start is at the Ignition Coil.....
Sitting on pin 1 (coil) should be 12vdc
Sitting on pin 2 (coil) should be a good ground

I read this part of the circuit as.....
This signal makes it's way to the Ignition coil and puts a voltage onto the Base of an NPN transistor, allowing current to pass from pin one (collector) to pin two (emitter), thus giving a current flow across the primary & secondary coils.

[PHIL069]

We have tested all the components in that circuit and the ECU is sending current to the coils.
We are now starting to test individual sensors, starting with crank and cam

[PHIL069]

If we test the output voltage of the coil pack to the spark plug (where the spark plugs plug in) while turning the engine, what voltage should we expect to see?

[silverGPX]

Could it be the switch that doesnt allow u to turn car on if car is in drive?

[PHIL069]

We have a manual gearbox!!!!!!
