Two things I can suggest right off: turn the starter and see if the tach bounces about 1/16th inch. It's barely perceptible. If it doesn't, I look at the speed and/or ref sensor. I just had identical issue and it was the speed sensor (closest to the firewall). There's a round shim under this sensor that's held on with the bolt and if it's missing, the sensor will drag on the teeth of the flywheel and damage the new sensor. That's what the problem was with my car. Clarks garage has a good article on checking the resistance of each sensor to verify failure status and how to remove them. Second (and easier) is to get a new DME relay (They're about $20 to $25 on line). Buy two so you always have a spare. Don't get the Uro ones. They fail about 1/2 the time when new. Get some other mfr or go to Pelican Parts. If you're unsure if the injectors are being pulsed, get a noid light at the auto parts store. They're real cheap and work great. Pull the injector connector on each injector (be careful you don't lose the spring clip) and plug the noid light into the connector and start turning the engine. The light will flash each time the injector is pulsed. Good luck with the adventure. Drop a line here when you finally find out what the problem was or to confer further.
