I had my car sitting for since february of last year, I would go outside and let her run every week up until september when the battery died. I purchased a new battery and put it in now all the power works but when i push the start button the car cranks but wont start ?????? this car has never had any problems what can this be ??????

i keep hearing it could be the little bit of gas that i had sitting in it or that i need a gas treatment????
has anybody seen this?
Any opinion will help me at this point...

 

If you had the car sitting around for a year you should of bought a battery tender. Maybe the alternator is messed up ?

 

I think the gas went bad.

How much gas do you have in it currently? Is it near empty?

At least for motorcycle storage, the best thing outside of draining the tank, etc. is to fill up the gas tank to the very top and if possible put some stabilizer in. The open air in a near empty tank will cause the gas to deteriorate faster.

I wonder how the high pressure fuel pump handles old gas too..

 

Does the new battery turn the engine over quickly or does it drag? Is there any sputter like its trying to start or just spins over? It could be a number of things, but I doubt it could come from bad gas.

Can you hear the fuel pump prime before you start the car? When you go to start it do you hear and see the radiator fans kick on?

 

you say that you went "outside" to run it every week. do you live in the city or in the country. If you have a code reader, see if there are any codes. leaving it set over winter outside is just asking for a mouse to take up residence under you hood. if you got a mouse and he chewed a wire, the best way to find it is with a scanner. if its not starting and not throwing a code i would try spraying a little, a very little, starting fluid into the intake and try again. if it sputters then most likely its the gas/fuel pump. Putting 5 gallons of fresh premium gas in it with a bottle of gas treatment and keep trying until you get it to start. When you press on the start button, you can hold it in and it will crank for extended periods, kinda like turning the key to start and hold it in the "old days". Also check your fuses and relays.
