I'm in the last stages of installing an 73 FI 2.0 engine into my 73 that had a carb engine in it. I've got 3 wires coming out of the FI wiring harness near the coil, but don't know for sure where to put them.
A black/red wire and smaller black wire are "bundled" together with a sleeve. From the Haynes wiring diagram it looks like the black/red goes to coil #15. I can't seem to find the black wire on the diagram. There is also a green wire that comes out of the harness by itself (not bundled like the two above). The only green wire on the diagram goes between the coil & the distro so it's obviously the condensor wire, not the one I've got. Can anyone tell me where these wires go? Also, can you confirm that #1 coil is also the one marked + ? I can't see the number markings at the moment and I can never remember which number goes to which +/- sign. Thanks! |

It's ALIVE!!! - Well sort of anyway.
With points & condensor back in it I've got spark and the engine started. It idles for about 30 seconds and then dies. It won't rev above idle. This is pretty much the same behavior I saw when I converted a 1.7 from carb to FI, but didn't change the fuel pump. I'm guessing at this point that I have a fuel pressure problem because I also couldn't get a reading on the gauge when I tried to check the fuel pressure earlier today. I've not run this pump before (bought it from a Rennlister, but haven't used it til now) so perhaps the pump isn't putting out enough pressure. Fuel pressure is supposed to be set at about 29 lbs. Anyone know what a pump is supposed to put out. I'm thinking of hooking the gauge straight up to the pump instead of the fuel rail. Enough for tonight. I can sleep better having gotten this far! If anyone has any other thoughts on what may cause this behavior, I'd like to hear them. |
