The car dosent start, no spark
The first thing a mechanic would check is for power and a ground signal for the coil. The pickup coil in the distributor sends a signal to ground the coil. The coil sends the spark to the distributor cap thru the rotor to the plug wires.

The simple fix would be to get a ratchet and spark plug socket and tighten them. First remove the plug wire from the plug and then use the socket to tighten them one at a time so you do not get the wires mixed up as to which one goes to which spark plug. Tighten them slowly to avoid breaking one of them but do not over tighten them either.

Could be fuel pump, is the pump running when you turn key on, you should be able to hear it. You are likely going to have to take it to someone with a pressure gauge to make sure it is getting proper fuel pressure. Fuel pumps commonly go on these vehicles
