Metering Unit TR6

[Corco]

Have just fitted a reconditioned metering unit on my TR6. Everything seemed to go well but cannot get it to start. Getting fuel to the injectors ad am out of ideas as to what it could be.

 

Any suggestions appreciated.

Hi,

If you enter your query on one of the general search engines you’ll almost certainly be directed to forums where similar issues have been discussed previously.

This is a link to a similar query on the TR Register Forum which may help?

Three questions to consider:

- has all the air been bled from the injector lines?

- is the choke cable adjusted so that the enrichment lever operates fully with the choke knob pulled out?

- is the new MU correctly timed?

If you need to bleed the air from the injector lines, then I find this device useful:

       

The usual advice is to place the injectors in a large tin, as shown, while you turn over the engine on the starter.    This makes difficult seeing which is spraying and which not.

This tray, made from simply folded alloy sheet, joined with pop- rivets over hematite sealed joints, makes any offender very clear , and leaves the injector tips accessible for pulling on if needed.   Since taking the pics, I've added some legs, so that it can sit over the throttle bodies.

NB only pull on the needle with the finger nails!  Never pliers.

That is neat! Think I will make one for the TR6.

Thank you for all the advice, bit of a schoolboy error on my part. When I took the MU out I did not notice the little red plastic drive dog, which dropped onto the floor.

After a lot of head scratching had a look round and there it was on the garage floor. Refitted with the dog drive in place and now the car is running. Need a bit of work on the timing but just grateful it actually runs.
