Hi all, new to the forum. :D

I recent purchased a barn find 1975 CSI. (Silver)

The fun starts here! Where to start ?

I am no mechanic, but keen to get the engine running.

Current state of play:

1) engine not ceased
2) turns over via battery
3) spark plugs dry, and have a spark to each
4) fuel pump filter cleaned, and pump running via key
5) fuel pressure at 2.5 bar, and circulating via fuel rail to injectors
6) injector contacts in distributor working

Problem is the engine will not fire.
It seems that the injectors and the cold start valve are not getting sufficient voltage to operate.

I have connected 12 volts direct via a spare battery and they pulse.

I have also turned the engine over via starter fluid, through the air intake, and it briefly runs.

Question I have are:

A) What voltage is required for the injectors to work in normal conditions ?

B) does the Ecu feed direct to the injectors ?

C) what terminals within the ECU confirm it has a power feed from the main relay ?

Any advice would be much appreciated.

Kr

Andy
