No spark at the plugs or coming off the coil, I have fuel at the rail. Believe me I have been over the simple stuff with a fine tooth comb. What I'm trying to figure out is why I'm not getting spark.

I hear you. have you taken out your spark plug and crank the car? I have found out with these cars it can be anything

If you have any problems, just drop me a PM.
On the spark, have you tried tapping the (-) side of the coil to ground? That should generate a spark. If it does, next step is to look at the sensors and the DME coil driver and see what the signals look like. All the signal and test point are in the DME/KLR test plan (service manual). If you don't have it, drop me a PM and I will get it to you, big file. There are two control signals to the DME relay that might be causing a no-start. Have you put in the DME relay jumper? Clarks has a nice description.

I believe i tried the jumper when i was initially troubleshooting, but i will try again to be sure.
Reno808 As far as taking a spark plug out and cranking, im not sure what that would accomplish? I already know im not getting spark.
I will be able to work on the car this weekend after i get back in town, ill try the jumper and setting the sensor gap, as well as checking for spark by grounding the coil... will post back with the results!
Many thanks again, im a pretty good mechanic, but the electronics side of this is kicking my ***. Starting to make me wish I hadn't sold my NA

Check your PM.

The DME relay powers the DME (pin 87)...that its name. Poor power or no power will cause all sorts of problems. The DME generates the tach and coil signals.

I wonder if there could be more issues with the under dash wiring harness for the fuse box? It seems like if there was an issue with the wiring for the DME relay you could have a no start condition.

I have seen several cases of bad contacts and wiring to the DME relay. If the relay get hot due to a high current draw from a defective injector, fuel pump, DME, idle controller etc. it transfers heat to the relay plug and wires. Its always a good thing to rule out.
I sent it, let me know if it gets through.
