You need to back up to square one on this. See if there is 12 vdc at the coil's small black wire with the key on. If there is see if there is 12 vdc at any of the injectors. One pin on the injector plug will read battery voltage the other a bit lower.

If there is no voltage at the coil then check the ignition switch. If there is voltage at the coil but not at the injector then check the DME relay. Also check that the red wires at the battery positive terminal are clean and tight.

You should hear the fuel pump run for a half second or so after you stop cranking.

You can bypass the DME relay by using a jumper from the battery positive to the coil's small black wire and putting a jumper from fuse #2 to #3 on the aux fuse block (the one without the cover, count from the drivers door).

If there is voltage at both the coil and the injector check that the HV cable from the dist. to the coil is good. Check that the rotor is secured with both bolts and the cap is on straight.

Once all the above is confirmed it's either the sensors or the DME. Note that the front sensor triggers the spark (through the DME and not directly).
