Engine starting and running troubles Options

[scoobykvn]

I have a 1970 1.7 and I need help. The first problem is my starting issue. I replaced the ignition switch and checked all connections and have found no issues. When I turn the key I get the oil light on and fuel pump running like normal. When I turn the key to start I get the oil light to go off and the fuel pump to run. All I get out of the starter is a click, most of the time. Every once in a while it cranks and starts right up. The starter is also new.

Now, once it starts I can't keep it running. Previously I could get it to stay running and it would run very high rpm for about 30 seconds then start to fluctuate and eventually die. I replaced all of the vacuum lines and now when it starts it will only run for a few seconds. My guess is the tuning is way off. If this is the case, how do I find a good starting tuning point so I can keep it running in order to fine tune it? It is still fuel injected and all standard tune-up components replaced.

Update:

The oil light does not go off, I was mistaken. I installed a hot start relay and the starter issue seems to be solved. After this I was trying to get the car to at least run long enough to tune it, and after about 5 or 6 tries to get it running, The fuel pump stopped working. I checked all of the connections relating to the fuel pump and they all seem good. I jumped the pump and it is still functioning. Could this problem still be related to the ignition switch?

Also, when I got the car to fire up and run for a very short time, It did not like any throttle input. It would start to bog heavily then die. Is this my throttle position sensor? When I press the throttle down I do get injectors firing until about 3/4 throttle, then nothing.
