1995 Pontiac Sunfire Front Wheel Drive Automatic

My car does not start sometimes when I start it. Can I know the reason why?

I'm not sure of the litre size of your vehicle? Can you check for codes? I believe your obd11 so you would need an obd11 code reader or scanner. If you can't check codes, can you do some of the basic tests?

I guess your saying it cranks good but won't start?

Can you check for spark at the plugs, depending on which engine you have, maybe you have plug wires? Pull a plug-wire loose, stick a known good plug in the boot, ground metal part of plug to metal part of engine. Have a helper crank the engine, watch for spark at the tip of the plug. If you have spark everywhere, check fuel pressure.
