Rover V8 EFI wont run pulling my hair out now!!!

[adam quantrill]

Wow - page three before someone mentioned the CTS!

Yes the injector click test is a really simple one and looking at this thread well worth performing.

To recap:

1. Ignition on.
2. Swiftly rotate throttle butterfly (under the bonnet)
3. Listen

Without the engine running it should be easy to hear a set of clicks.

If no clicks, then:

1. Check throttle pot operation (see http://www.vintagemodelairplane.com/pages/Rover_Te... )
2. Check the connections to the ECU
if still not working check power to the ECU, or swap out the ECU with a known good one.

The clicking tests out the drive circuits of the ECU, power, grounding, etc.

Thanks Been out today reset throttle pot checked wiringing, sadly still awaiting starter thought it would have been here by now,, have bailed out now feet and fingers starting to freeze, how do tools become that cold!!!
If I get to ECU stage which I think I might anyone know were to get these tested repaired , I am near Ashford kent

Hi

These guys are in Rochester, I had a friend have his ECU rebuilt and it cost £200 with a lifetime guarantee ...His Wedge was transformed.....

CSI = Cold start injector

Also CTS = Coolant Temperature Sensor.

and the ATS = Air Temperature Sensor....

And the MAF, don't forget the MAF!

Mass Air Flow sensor: https://en.wikipedia.org/wiki/Mass_flow_sensor

My car has one anyway

Is there no one that you could borrow off just to test it? They are regularly in fleabag for less than £80.

and in my experience problems with the flapper system are typically multiple issues and not just one thing. You have to be methodical.

Fully agree with this. Wendy was running very poorly. Went through things methodically. Vintagemodelairplane site I linked to on page one was very useful and the time spent reading it was not wasted.

I ended up checking all the 'circuits'. There were plenty of 'faults' but I didn't find one single cause. She finally started running 'right' when I checked the continuity of the ecu wiring. The continuity tests didn't reveal any issues.

One final thing was that I had a rolling road tune done and they also found some issues inside the flapper unit - which they dealt with.

There's a glitch in the matrix.

What is the part no. Of a flapper ECU does anyone know? Can't get at my ECU flap very easily in the garage! Be a handy spare to have on hand and £80 could be got back easily if not used.

The reference number is PRC 4764.

Nothing to do with me but there is one of flea for £79.99 right now:

And another for £115:

Cheers for that.

Or send your ECU to Mark Adams.
He will test it for you and will be able to repair or upgrade it if required.

[jensencars]

Have seen the ones on eBay but you need to be 100% positive it's a good one or you will be going round in circles

[jensencars]

Mailed the guy with the £115 one he said he doesn't know if it works or not

And you need to suspect the fuelling first...

... did it run on ez-start?

If it does, all the spark, dist, caps, leads, timing, valves, pistons etc are fine.
Else we may never know

[jensencars]

Have easy start been waiting for new starter motor solenoid burnt out on old one, it's here now but been to cold to be fitting it !!!!!

Carbs - no messing with crappy and unreliable not to mention ageing Efi.

I know of a spare working one. But agree that Mark Adams can repair. Python Racing may alos be able to help with repair as well. Paul Smith is another but I'm not sure if he is still trading.
