There are many things that can cause the light to come on. Generally if it is serious most 'check engine' or 'service engine' lights will blink. The simplest (and cheapest) method to diagnose the problem is to take the car to AutoZone and they will read the computer codes free of charge and tell you exactly what it is (such as the oxygen sensor got a bad reading and needs a reset, or its time for an oil change... etc.)

Service engine soon light


Not exactly.
The fuel pump would not cause a trouble code, but low fuel pressure could.
Have you checked fuel pressure and the computer for trouble codes ?

If it won't start have a compression test done and see if one bank doesn't have compression . The intake cam is known for breaking at the front lobe

Pulled out of my driveway it hesitated than took off went about ablock and died tried to start it and wont start


If there was not service engine soon light, good chances are that your fuel filter has reached the end of it's life and is to dirty to allow the fuel to flow through properly. Start with the simple and replace the fuel filter after you inspect all your fuses to ensure your fuel pump is still working.

Thank you for using fixya and a dirty fuel filter or faulty fuel pump will not set the service engine soon light to come on.

When I start my 2001 alero the anti-lock, traction light, service engine soon, service vehicle soon lights all stay on all the time. But my car seems to be running fine. Why is this?


the anti-lock and traction lights will come on together if there is a common problem with the two, since they are closely related. may be a wheel speed sensor or something similar. the service engine soon light indicates a problem with the engine computer, can be anything from an emission system problem or an engine performance problem. all of these lights can come on with no apparent running problems on the car. the service vehicle soon light is basically a maintenance reminder, an oil change light. take the car into a shop and have the codes read for these lights.

If it has miss and hesitation only warm not cold you may have a coolant temp sensor problem . but if the service engine soon light is off i would chek ignition system(plugs, wires ,boots).most likely one of the cylinders missfires when hot.
