If it's like mine It's your security system, try unlocking the doors from your keyfob, then start it. It is a security feature to stop people from breaking a window, breaking lock then stealing your car. it will either wait 20 minutes, or you must unlock a door from the keyfob or by using a key in the outside lock, and not by the inside lock button.

Repair the car

key less entry system goes thru key decoder.common and likely problem is key tumbler assy. wires (small like speaker wires) breaks off key tumbler which will cause security light to flash or stay on. tilt whell up or down, sometimes vehicle wires to tumbler will touch enough to start vehicle. if so, vehicle can be driven to repair shop for repair. est for complete service.. aprox 350.00

Could be something in the distributor cap, a blockage in the fuel line, even a bad timing chain.You need to know if you are getting spark to all of the plugs, fuel pressure to the injectors, and normal compression. If it is a fuel problem you should be able to spray carb cleaner into the throttle body to make it try to start. If you have spark but at the wrong time, it will backfire by firing on the wrong cylinders. This can be caused by a faulty dist cap or rotor, or the timing chain.

the fuel pressure regulator will not do it. you need to look at spark plugs ,wires ,air filter, fuel filter. tires pressure if tires are under pressure can cause bad gas mpg

Whens the last time you changed tranny filter and fluid. it may be the vacuum modulator or your bands inside the tranny. Pull out your tranny dipstick when running and check level of tranny fluid. Add dextron II of needed. Smell the tranny fluid on dipstick to see if tranny fluid is burndt. if you change filter and fluid, add a can of trans-x to the fluid. Will help seals in tranny.

may be an oil pressure issue. Happened all the time to 2 of my customers. one was fixed with a new oil pressure probe. The other was a new oil pump & pressure unit. May not be your problem, but try again with a fresh oil change and see if it still does it.

possibly low on power stering fluid or maybe over due service

You need a noise filter on your power line to your amp it sounds like be cause your filter cap on the alternator or distributor is not filtering out the noise.

In the bottom of the distributor under the plate there is a coil with hair-fine wire, a broken wire there will cause the no-spark issue for sure, check it with an Ohmmeter for continuity, good luck!
