Help, broke down!

[DeeTurbo]

The cable goes down and there is a second plug lower down on the block that you could take the readings off. It's yellow and might be cable tied together.

[tbaxter08700]

Brilliant mate, muxh easier!

Right when I hook up to the yellow plug that comes from the fprs I got nothing at all. When I connect to tje yellow plug that im assuming comes from the fpr I get 8.6 on the glow plug posistion and 7.6 when cranking.

[Poodle]

That's not right, what are you measuring in?

You should be getting at least something from the pressure sensor, if there's nothing showing i'd be having a good look at that.

[tbaxter08700]

   

That mate.

There's 3 wires from it isn't there, a green pink and white. Does the pink and white go to the fpr and the green a live or something?

[Poodle]

Not 100% tbh, one is power, one's an earth and the other is to the ecu i think.

Did you manage to sort out an autodata account? That'd tell you which is which.

[tbaxter08700]

Havent been to to compuer mate but will sort that out tonight.

If there is nothing plugged into the sensor then it wont be powered will it so I wont get a reading? I dno!

[Poodle]

Erm, no. Why would you unplug it?

[tbaxter08700]

So I can put the multimeter in to it to get the reading. Got autodata on anyway but not sure what to look for.

[tbaxter08700]

Defiantly something up with the injectors as they measure 0 ohms and as it shows here in autodata they should measure 0.2ohms.

   

[Poodle]

Yeah stick your mm needle into the wires.

[tbaxter08700]

Dont have mm needle lol will sort it tho and get back with a reading.

Something has shortened all the injectors tho don't you think?

This might help. Password is the same as the album title, but all lower case with no spaces

[tbaxter08700]

Cheers for that mate will have a good look through them.

Where abouts in autodata is all that as I have it on the pc.

[Jonny81191]

It's not..

I "acquired" it through a guy I know who's an RAC patrol.

[Poodle]

I've never heard of the injectors being "shorted out" and i'm not even sure it's possible. Plus you'd struggle to do it with the voltage generally found around a car, especially considering it takes 80v to fire them compared to the 12v everything else uses lol.

Two minutes on google and i found this for you: http://www.obd-codes.com/p0200

I still think those codes are a red herring myself, can't understand how braking hard would have affected the injectors at all.

Any luck finding someone/some program that can sort you some live data?

Brilliant read mate, will try all that when im home later. Wouldn't I of got that code tho when I read them if this was it? I dno, its strange I have no codes now I have cleared them

I know what your saying about not being able to but its just they defiantly measure 0 ohms which they shouldn't according to autodata.

Yeh, I have someone coming at the weekend with a pp2k but would like it sorted before then lol I have autodata now but I guess it can only help so much!

[Poodle]

Yes, I would expect the codes still to be present if the injectors were genuinely at fault. Still reckon its likely to be a connection or loom issue somewhere myself.

[tbaxter08700]

Well I will check all wires and loom later. So it should see 80v when cranking?

Forgot to put this yesterday. This what I got when I measured the injector connectors

[Poodle]

You should see pulses of 80v, you might find your mm isn't quick enough to record them though tbf. Will have a look at that vid later.

[tbaxter08700]

Ok mate and maybe. Will buy another one later to confirm.

Cheers

[Poodle]

Youll pay big money for one that can measure cr injectors pulses tbf, be better off buying pp2k imo.

[tbaxter08700]

Oh right.not sure then. In the video it fluctuates between different volts so I dno.

---

What do you think about getting someone out to diagnose it? Think they will have the appropriate software.not sure how much they would charge tho.

[Poodle]

Don't know tbh mate, depends how desperate you are to have it back on the road this week. I think most specialists charge at least £100 for a call-out, and a lot won't guarantee they'll fix the problem for you either.

[tbaxter08700]

Stuff that then lol

[Toms306]

Yeah, you need like a picoscope thing to measure the injector pulses lol! I doubt you'll do it with a normal multimeter as we couldn't with the college ones.

Are you anywhere near a garage? If so, I'd tow it down to ask them to have a 5 minute look for a few beer tokens to see if they find anything you missed. They'll probably stick it on a decent code reader as well. Cheaper than getting an auto-sparky out lol!

[Tom]

Oscilloscope type thing Tom?

[Toms306]

Oscilloscope type thing Tom?

Yeah, Picoscope is the brand name I think.

Huge piece of equipment that looks like its been nicked from the cardiac ward at the hospital....

[tbaxter08700]

Not really near a garage.

This is what I have found

Frps 1.3v OK

Fpr at multi plug 0.3 ohms OK

Fpr at connector 11.4v OK

Crank posistion sensor 11.2ohms ???
Should be between 315-405 according to autodata.

Could it be the wiring going to it or probably the sensor?

[Toms306]

405Ohms? Is that through the sensor? That's massive resisitance, sounds like its shorting out inside the sensor if its as low as you say.

[tbaxter08700]

Yeh it is mate
