My son's 91 sedan would crank over nicely, but never try to start. We sprayed a short shot of ether into the air intake and it started instantly. This proved that we had ignition, but not getting fuel to any cylinders. A shop tested for the electric pulses to the injectors and saw none. He then disconnected the wireing plug to the one injector that is accessable, and the engine started and ran on 5 cylinders. That one injector was shorted and was killing the pulses to all the rest of the injectors. If the bad one was one of the ones that are buried under the cover, we may never have figured this one out! Jim Harlan, Albuquerque If the above-answer didn't help, check your fuel pressure. You might have a bad fuel pump or pump relay
