I replaced the head and head gasket on my sunfire. I also replaced the starter and battery and now when I try to start my vehicle it wont fire. I am thinking it is the computer itself. What is your opinion. Thank you

I suggest rechecking all your work, because if it started prior to the repair you may have missed something.

Changed head gasket and now wont start at all. When i go to start it back fires out of the throtle body. Is this my timing?


Sure sounds like your timing, or it can do this if you didn't properly adjust the valves when putting the head back on.

2000 pontiac sunfire replaced head gasket now it still wont start, it just backfires


It sounds like a timing issue. Make sure the cam shafts and timing belt are installed correctly. Hopefully you have not belt any valves while trying to start it. Good luck.

New starter 5months ago, now wont start...Getiing power to the radio and dash lights.. just makes a click noise. Try to bost it. It will jump start. could it be a Relay?


If you can jump start it from another vehicle , the starter is not the problem. Most likely a low battery , or dirty connections at the battery posts / cables.

Car turns over but does not start. Battery good


If it over heated, could have bad head gasket's, fill radiator with water, crank engine with radiator cap off, if water is push out of radiator while cranking, bad head gaskets', also remove spark plug's, crank engine if any water, bad head gasket, also when spark plug's removed, check for any water on them.If there is any water on plug's, bad head gasket, also could try doing a cylinder compression test, if bad compression, head gasket, no compression, wont start that way.

Why wont my 2000 sunfire start?


starter relay,ignition switch,park switch.need to use a volt meter and start at the starter,see if you have at least 12 volts.if there is have the battery tested.does your head lights come on?next no voltage, go to the fuse box under the hood and check for (2) 12 volt powers with the key on and a good ground.if ok replace the relay.next move the trans shifter to neutral with foot on brake and try and start if it starts you need park switch.if not next is the ign.switch to test,you will need to locate the starter wire and check for voltage when starting if none replace the ign.switch hope this helped.also the alternator has nothing to do with the cranking of the engine on this car.

I replaced the head gasket on my 97 Sunfire it doesn't start


If your timing is off you will have no power.check and make sure all timing mark's are correct.Some engine's are contact motor's,which mean's if your timing is off you could cause damage to valve's or piston's.Also you should do a compression test to be sure each cylinder has adequite pressure.Hope this help's.
