Hello,

The coil pack is likely overheating for having excessive internal resistance.
It can also be triggered by spark plugs.
Since you are not getting any spark it could be due to faulty coil or bad spark plugs.

Here is the ideal resistance for the coil:
Primary resistance : 0.78 ± 10% (Ohms)
Secondary resistance : 20 ± 15% (k Ohms)

As for the fuel pump, if the pump is inoperative. It could be due to a bad pump, relay or wiring.

Please let me know of any questions.
Thank you.
