Turns over but why doesn't it start?

Hi,buy some easy start and spray into carb or air intake and that should help it start,hope this was some help,all the best.

Have the cold start fuel inkector checked for flow.

Can\'t really help you with the no start problem without more information, but would advise you to stop using starting fluid right away. Starting fluid is hard on Diesel engines but they are made for much higher compression so will usually survive intermittent use of starting fluid. Gas engines just plain can\'t handle the much higher than normal compression that starting fluid produces which will destroy valves, piston rings, connecting rods, starters, ring gears on the transmission and head gaskets in short order. If you don\'t want to have to completely rebuild your gas engine don\'t use starting fluid on it ever!

The year make and model would be handy to know.
You would need to check the fuel system and find out why you don't have fuel to the injectors or carb.

the little black pin is to stop the needle going back dont think a jump start would cause that but if when you jump start and terminals are reversed polarity if could fry the battery cels

Check fuel line fuel pump

If the car is getting power from the battery(lights turn on; radio turns on) when you turn the key, then it is your starter or gas distributor. To test that, you need to pour a little gas right in the hole where the engine and intake meet. Pour a little gas in that hole. If it starts up, then it is your gas distributor that is the problem not giving gas to the engine. If it doesn't start up with gas in the engine, then it is your starter. Either will be $100-$200 fix at a shop.

Sounds like you might have a fuel delivery problem, being it tried to start up after you gave a shot of starting fluid tells me theres probably a no fuel pressure issue with it, check the fuel pump fuse and relay and make sure they all check out fine, if they all appear to be good theres a good chance that you have a faulty fuel pump and will require the fuel tank be removed to access the fuel pump for further inspection....

pull the plugs....could be full of water and coolant....experiennced same symptoms a couple of weeks ago on a customer car....good luck...Lee

try a little starting fluid and if it starts it might be the fuel pump or the fuel filter .. starting fluid will let you know if its a fuel problem or just what .. thanks Jerry
