It could be your timing at the distributor and oil pump.

When you installed your oil pump and distributor did you line them up properly.

There is 3 steps to setting your timing.
First you have to set your crank at TDC and set the cam accordingly.
Second, when you install the oil pump and distributor, you have to stab the oil pump shaft properly.
Third is when you adjust the time with the timing light.

Set your engine at TDC and pull of your valve cover, make sure your cam sprocket is aligned properly. If it's aligned properly, then remove your distributor and look down the hole and look at how your oil pump shaft is positioned. The end of the oil pump shaft looks sort of like a upper case D (do you know what I mean?). Looking down the hole, the shaft should look like this "(\". Once you stab the distributor back in, the rotor should point at the 4 O'clock position. That should set your mechanical timing and allow you to start the car. If it cranks but doesnt want to start, twist the distributor a bit to either direction and see if it helps. After you get it started get a timing gun and set your timing to the second mark from the right. Once you finish that you should have your timing set.

Also, make sure you have your firing order on your spark plug wires on correctly.

It goes: Starting from the 11o'clock position clockwise 4 3 1 2

And make sur.e you gap your plugs right too, they're supposed to be .44

ok

well when i stab oil pump/dizzy the rotor was facing at 4 o'clock and

when i turn dizzy towards car revs more and higher idle more responsive and turn it other why idle go down and car acts laggy spark plug are gap correctly



Could some of the sensors on motor be bad? or still dizzy timing

See if you can rent or borrow a timing gun from autozone. Then adjust your timing.
