You electrically disable the cold start injector by disconnecting the cold start injector from the wiring harness.
You then place a tolerant resistor of the same load as the cold start injector.
You do this as the cold start injector driver in the ECU expects to see load. A fault code is indicating a faulty cold start injector, otherwise.
The next and somewhat messy step is:
- At least removing the cold start injector from the fuel line, then plugging, removing or something with the fuel line.
- You then remove the cold start injector and plug the hole using the same cold start retaining hardware, a cover shaped to fit the cold start injector hole, and some gasket method, appropriate to the application.
Indeed, why in Bosch LH-Jetronic 3.1, Bosch remove the cold start injector complete. Yet you only have the Bosch LH-Jetronic 3.1, and corresponding EZK ignition, on Volvo 240s 1988 or so and newer with manual transmission and no EGR.
Others can direct you to the procedure. You may want to use Google and target brickboard.com using search terms. Include in the search field the expression, and without quotes, "site:brickboard.com" or, maybe better, "site:www.brickboard.com" The www limits the network protocol the search engine uses to search the domain of your interest, I believe.
