Transit t350 Mk7 starting problems

[richy_B]

Pulled the ignition covers off. Disconnect, cleaned, had a look at and reconnected firmly all the various plugs. No difference.

I took off the black item, which I think is the tranceiver/part of the immo control. The fault code changes to 11 - immo control not connected. I assume this means this item is the immo control and the likely cause.

I plugged in my ibc reader incase but no codes come up (no engine warning light so makes sense).

Checked batteries and one was 12.6 and other 12.5 sp I don't think thats the problem.

How do you check the earth is good? Just that they are connected/intact?

Where it was attached to the body it had rusted badly and needed re connecting

I'll have a look when I get back. That's bits often covered in mud and gunk so could be an issue.

 

Do you remember if you were getting a flash code like my '12' ?

Not sure, but my dash display looked like a disco[emoji23]

It was filthy underthere but doesn't seem to be the issue. I think I'm going to have to try a dealer.....

Been driving around all today. Stop, start, no bother at all. Just back at the yard I tried to turn it on again but it wouldn't start. Red light on the dash display flashing constant red. Got out, locked it, tried again - nothing. If I flick the key round quickly it tries to start for less than a second then stops. I'm 99% sure the immobiliser is kicking in.

 

Tried the spare key, no change so don think it's the key. Assume it's not being read by the van.

 

Pull the battery and left it out for tonight. Fingers crossed it'll be fine tomorrow when I plug it back in. Maybe not though....

 

Anyone had this? Any thoughts.

I had almost the identical problem with my tipper , spent hours on the immobiliser , eventually traced the fault to the fuse box above the glove box . One of the boys had spilt coffee down the dash , took the box out and opened it up and found a bad/damp joint , managed to resolder the joint and it worked fine again .

I had a photo of it somewhere , I’ll try and find it .

At the back of my mind i keep thinking about it being snow covered for a few days.

Spend your time at work and take it to a garage who specialises in ECU issues.

Possibly crankshaft/ camshaft sensor but there are several other sensors on that vehicle that are all linked to the ECU and if faulty/intermittently faulty can result in the symptoms you describe. Can't rule out fuel delivery system issues either.  Good luck.

You jinxed me Richy. Went to start my Transit this morning and the engine said no. New Battery and all sorted.

 

I'm sure my mate had the same problem as you. It was a relay for the ECU. Might be worth checking.

Well I'm back on the road! I thought I'd have a punt on putting a new transponder in. Ford only, £131 plus VAT. Doesn't need coding etc, just plug in and off you go.

Cheers for everyone's input.
