I have a 1993 5.0 mustang. It is hard to crank and when it does it has a rough idle almost like it has a bigger cam. It bucks on the road and has no power at all. I got it from my brother and he replaced the fuel pump, fuel filter, distributor cap and rotor button plug wires, plugs, he said that he took the pickup assembly out and cleaned it and also took the mass air flow out and cleaned it with a electrical spray cleaner, and the computer was rebuilt because he had ants in it. [? ] I found that the firing order was wrong against what I had so now it is [ 1 3 7 2 6 5 4 8 ]. It didn't help much. I also found out that he has been adjusting the timing by turning the distributor so I got the light and tried to set it back at 14 degrees, what I was told I have no book yet. The mark was jumping around and I could not get a good reading. I was also told that there is a plug that needs to be unplugged at the distributor to be able to set the timing but all I see is the control module plug. Before the fuel pump went bad the car ran fine and was pretty strong considering the mileage. What do you think I need to do or check next?
