Get the codes. A '94 would be an OBD I system.

Go from there.

Make sure the battery is well charged.

Check the wiring in the ignition circuit for loose connections, corrosion, broken wires.

Check for dampness in ignition wires. How old are the plug wires?

Make sure the spark plugs are good and properly gapped.

after countless hours on the web i came across a way to test the 4 wires going into the coil 1 is a power the other 3 pulse telling that coil to fire 2 of them are reading almost no voltage with the 3 rd reading about 10v on the pulse what would cause this ? the computer? if so do i need to have it flashed when i replace it ?

but yea checked the wires and plugs they are good so im still stumped changed the tps map and crank sensor today also still no run

Are the cams turning? How old is the timing belt? Start with the basics.
