I finally got the ignition and fuel pump hooked up on my 76 2.0 L and the engine cycles between reving and stalling when I hold the pedal down to get a fast idle. What do I need to be checking now?

Two suggestions, one take photos of your engine bay and post them.
Second suggestion which is what I would do, is to very carefully remove your FI harness. Then label each connector on it with tape and mark it exactly as shown in the diagram I sent you; A, B, C, D etc.. Then, find each associate sensor, etc. and mark that area with tape and label it; A B C D according to the diagram; example "I" = coldstart valve. Then use the diagram as a check list as each piece is connected. That should help in getting it installed properly and minimize any connectors in question. Otherwise it looks like a birds nest of wires. Hope that helps. |

I determined that the fuel injector wires were mismatched on both sides of engine. I found all the little wire numbers just as described. I verified wiring on the air inlet and down near the bottom of the distributor, the wiring loom for the distributor connections and the head temp were routed wrong such that the head temp wire could NOT reach the sensor, so I rerouted that so all wires could connect like they are supposed to. I have one wire from the coil wiring loom that I don't know where to land. Where does the RPM tach meter wire to? Engine sounds excellent! I was finally able to move the 914 over to the first car bay where the heater is so I won't be freezing my tail off anymore. I am SO excited! Pictures later this weekend!
