I got a M-tdi pump what's the plastic cover thing?
« on: May 11, 2018, 01:20:50 pm »
 I bought an mtdi pump from William Smith.
 It has a plastic cover over the fuel stop solenoid.
Here's a pic:

How do I remove it?

I have seen that before on a pump.  I don't know what its function is and I don't know how to remove it.  I do have confidence that you'll get it figured out, though.   :)

Plastic part, plus hacksaw blade might equal removal here.

Ahhh the simple solution. I was going to grab the cutoff wheel.
 My buddy ran the part number on the cover,.. I'll post it later.
 It looks like 2 bolts clamp the plastic cover onto a normal 1.6D looking stop solenoid.
 We'll see why there are 3 wires.

Just looks like a cover for the stop solenoid really.  Not really needed, three wires Eh?   Will be interesting to know what it hooks up to.

AFAIK its the pump side component of the immobilizer. Some force and a chisel was involved when I took mine of.

Hack saw worked great,.. just a regular 1-wire stop solenoid under there,.. more circuitry than I expected.

Here's where I cut it:

The one bolt got cut but the other one loosened up and came out easily.

And here is the stop solenoid with the cover removed:

What was the other circuitry used for?  Any ideas?

 No, there was more circuit/chips than I expected
