You may have fried something in the ECU. Check the wiring to the distributor.

So if I did fry something what needs to be replaced? The ECU or the Distributor or Both and how will i be able to tell? I'm wondering if it has something to do when I jumped that car?

Most likely the ECU, unfortunately. Pay special attention to loose grounds and connections. There's also a control module under the right front seat. The grey wire there feeds the tach.

The tach signal comes from a couple of sources. There's a crank position sensor in the distributor, and the negative, or tach side of the coil. Those feed into the control module I mentioned above, which generates the signal to the tach.
