1997 Saab 900 SE Turbo. Problem repeats. Car is off the road. Had started up just fine, several days in a row, now it turns over just fine but does not start. Can hear the fuel pump pressurize. HAd done...
start with the basics: an engine with no internal problems (like timing belt broke, or valve train not timed) needs fuel and spark to start.Since your getting fuel up to the fuel rail to feed the injectors, lets assume for the moment that the injectors are working to put gas into the cyllinder (You coud check that by pulling a plug or two out and see if they are wet or smell of gas.) Then check for spark (Hold the metal tip of plug wire 1/4 inch from a metal bolt or ground on the engine. Careful you don't get a shock-you can also buy a spark checker for a few bucks. just put the plug wire on it and ground it with the clip. Then you won't get a shock.) If you see that it is getting spark, then you may need an expert diagnosis for why it won't run. If you do not detect any spark (might want to try more than one plug wire) then you need to diagnose your ignition. If your car has a distributor, take off the cap and check inside for a cracked dist. cap or bad or worn rotor. You may also have a bad ignition coil or ignition module (expensive, but not as expensive as a bad engine control computer. Distributorless ignition? Again, may be a bad coil, coil pack, or ignition module. good luck, i'm about out of suggestions.
