Any codes? I had a cam position sensor (the one in the distributor) go on a 93. If it's that, sometimes you can tease it into temporary life by turning the ignition on, then going and unplugging the distributor connector and replugging it (with ignition still on). It's good for one start per operation, a hassle but could get you home. If it works, you've also tested the cam position sensor and found your failure. On the Renix system, sometimes you could do something similar with the crank position sensor to get it to start. Might be worth a try.
