testing FI parts Options

[eg914]

I am new to this board, and have a question that I haven't found answered in searching the forum. I have owned my 914 for about 7 months, and love it. It is my daily driver. It is a '74 1.7L (does that seem right?). The PO had installed a progressive carb. I bought the car with a box of FI parts. I think most/all are there, but don't know if they work. The carb is giving me fits in the mornings. How do I test the box of FI parts I have before putting them on the car? It looks to be the appropriate D-jet injection for the 1.7L. I would like to have the FI working before winter.

Thanks in advance for your help

there are lots of easy tests that can be made of the components, like the vacuum holding test of the manifold pressure sensor and the electrical resistance of same. one thing i would suggest is to check the continuity of the wiring harness so you could eliminate possible snafu's from that. one source that could be used is the diagram in the clymer/lash manual. there are 2 good diagrams in it: 1) looks like the harness in that the connections are "to scale" or at the actual location along the harness in the pix just like the real harness. 2) is a diagram of connection pin #'s and pin numbers on the parts, that is, the pin on the connection plug is shown and the pin on the, say for example, the aux air regulator is shown.
