Hey guys so I've rebuilt my wife's engine all fresh ect. It's taken 3 years I know a hell of a long time. Connected everything up she turns over but not firing. So I assumed spark so got new spark plugs, on taking the old ones out they where bone dry. (New ones in anyway) I depressed the Schrader valve on the fuel rail to see if there was pressure. She squirted out. What can I check next?

Kind regards

 

Power/ground to injectors?

 

What do you mean mate? May have missed something out here

 

Check for power - check for ground from ECU, ideally get a noid light kit they're checp off ebay, simply plug the injector in in turn and crank the car, the noid light will flash if the ECU is switching the injectors.

 

Thank you will get one of those and give it a check.

 

Worth checking all the wiring you've had disconnected to see if there's any pins pushed in /bent also.

 

Il get on checking all of them. So I did get a new crank sensor and I didn't actually put it back on. So it's on now still nothing. Checked to see if there was a spark. Couldn't see one and the bottom of the pugs still looked dry. I'm going to drain the fuel out of it as it's 3 and a half years old and clean the mesh/gauze. Also do you know what this wire is as I can't figure out what it's for.

 

No idea sorry

 

Ok mate thanks. What's the easiest way to get to the fuel pump?

 

Also put the noid light on in the connection on the far left on the injector rail and there was no light. What would be the prognosis on that? I assume ECU is fucked

 

With the noid light, if when cranking there's no light you need to see if there is power going to the injectors with a test light/multimeter.
the ECU will carry out the ground, if the ECU is ok.

 

Where will I use the multi meter? I.e test the ECU? Not the best at electrics

 

There's 2 connections on each injector wire, live 12v+ then the other is switched ground by the PCM/ECU Need to check that one is power when cranking if you have power then check with the noid light the ECU switching when cranking , if the noid light does not flash at all when cranking you really need a wiring diagram to see where the fuses and relays are.

I'm sure with a bit of you tubing you can find step by step guides how to do it.

Looking again at that wire looks like a ground wire thats snapped/corroded off , see where it reaches you'll find where youve snapped it off from .

Further than that you;ll need to get the fault codes rread, might give you more of a clue, but be weary that there maybe lots of codes that have been man made during your 3 yrs job.

​​​you are talking about those connections to the injectors aren't you mate. And looking at the broken wire it seems like it's a broken ground. Not 100% sure where it goes though..will have to dig around on that

 

Also found the broken earth wire. Connects to the side of the gearbox so will be getting that sorted now

 

Yeah the injector plugs look like that.

 

OK so illve had a quick look. Put the multi meter on the injector harness and nothing. So check a few connections and nothing looks bent or anything. I put my scanner on and it came up with cam position sensor no signal so cleared it off and it tried to start then just carried on to turn over but still trying a little bit but same fault code P1345. Changed the sensors from a spare engine I've got but much the same.

 

You've probably got no feed to the cam sensor wiring if you've tried sensors

Wasn't an ST but was a mk2 Focus, I had a problem with it kept blowing a fuse that fed the VCT solenoids and coil, had a shorted out wiring harness on top of the gearbox.

Check all fuses!

 

Looks like P1345 could be a cam/crank correlation code as well, did you use the proper tool to set the cams?

Did you get the non signal code descripton from scanner?

 

I did read that too. I didn't use a cam tool. Everything was marked up. I'm thinking I'm guna need to buy one. Ye the code was from a scanner.

 

Did you fix that broken earth wire.

Seems like you have a few issues that will stop it starting, difficult to fix from afar! I used to live nr Worcester J7 M5 so not too far frm Kiddy. Shame I wasn't nearby now!

 

That is a shame. Ye I'm just waiting for a new bolt to hold it on properly. Think il have to go through the wiring and check all the connections. And I think il get a proper timing tool too. Just expensive

 

And assuming there's no signal there is no power getting to the sensors!!??

 

Exactly but you need to test the wires, like I posted before check all the fuses, start with the basics.

 

All fuses are good. Checked all of them. There is a connector I came across whilst putting the new crank sensor ok.


so it's the one that's circled. It spurs of after the crank sensor connector.

 

Have you had the gearbox out too? Reverse light switch maybe?

 

I did have the gearbox out as it was easier to get it all back together and slot it in. Will have to have a look at that. But I think your right there mate.

 

If I remember, the reverse switch is under the shifter where the gear cables go on.

 

Yes mate your right. All connected. So I've put new cam sensors on and I checked with a multimeter to the cam sensor and it came up with a reading of minus 1.12 to minus 2. Something.

 

Without a wiring diagram its hard to say wht each terminal should read on the cam sensor, how many wires is there?

 

I've got a whole PDF of wiring but I don't know how to send it over here. My mate sent it to me through what's app. I'm going to check the ohms when I finish work

 

 

That's the engine electrical system and the symbols sorry there's so much.
