ford tempo starting problem - no spark? - still

A couple of months back I had troble with my Ford Tempo not starting and draining the battery fast. Someone suggested the starter. I let it sit for the last two months, because I have not had time to work on it yet.

This weekend, I put in a different starter, and the car does turn over, but will not fire up. I have put in a new TFI module, a new coil, and a new relay as well. If I put a spark plug on the end of the coil wire, and try to start it, I just get a orange spark. I checked each cylinder off the distributor, and each of the four wires has a spark, but it is a dull orange spark. Even before the distributor, the spark seems weak.

Should I not be getting a bright blue spark?

I cleaned and sanded all the grounds, and reverified the coil was working. The coil has the appropriate measurements per the manufacturer specs. I checked the fuel line and it is putting out gas. I pulled out each (new) spark plug, and they do smell of fuel.

I am sure I am so close to getting it running, but don't know what to do now.

Anything else I am missing? Help, I am at the end of my rope.

Thanks
Dan

You have an ignition problem. The spark should be fat, blue and consistent.

Check the pickup in the distributor for one possibility.

Ignition isolation?

Should disconnecting the coil wire from the distributor, and installing a plug on the end of the coil lead, not isolate the distributor.

I have done this. Trying to start the car with only a spark plug off the coil, I still get a dull orange spark. Would this not mean the trouble is prior to the distributor?

There should be a radio noise suppression capacitor connected to one side of the ignition coil. They sometimes short internally, which can cause a weak spark. Disconnect the capacitor & see what happens.
