Assuming that the starter is rotating and turning over the engine. Check for spark Check for fuel - You can get a can of starter fluid form an auto supply stoe - spray a little into the intake. Car should try to start - if it atttempts to run for a few seconds then the problem is fuel relatedm if not then it is spark related.
I checked fuses and replaced blown fuses and now it won't start.
Check fuses as the battery change should not initiate a "No Start" condition.
Start simple- check the fuses and battery. If those are good check the starter.
It is the VAT system, thinking your are a car thief. Repair or replace the system.
Is this an automatic or manual transmission?
If your headlights, horn and everything work, I would have the ignition switch checked out. Make sure you checked all ingition fuses and relays first.
Check ignition relay. Jump the battery directly to the starter and see if the starter is any good.
Check all earth wires from battery to engine and earths from body to engine
You may need to have your starter checked. If the radio comes on, then its not the battery. Does the truck make a clicking sound when you try to turn over the engine. If it makes a click -click noise when you try to start, then its not your starter.
This problem may not be make and model specific. Usually when it takes a long time to start your car, there is a problem with the starter or the fuses that help start your car. In addition, your battery could be wearing out (check for corrosion as well), this can make it harder for your engine to turnover. I recommend having the fuses in the starting system and the starter itself checked out by a professional mechanic. If your battery is old, you should probably change it because a stronger batter could provide more electricity into your power system, making your car start faster.
Sorry but your question makes absolutely NO sence whatsoever! do you mean that you have already Changed-(with an A, try using spell checker next time pal!) your battery with a new one and your vehicle still will not start? Have you checked ALL fuses and relays related to battery, starter, altenator, ignition and fuel pump? Have you checked ALL spark plug wires? distributor cap, spark rotor or coil pack wires? Have you checked for fuseable links and if your vehicle has any are they bad?
The battery does not have sufficient voltage to start the car when it's cold. Have the battery checked out. If it still goes click click after running the car for a while, have the alternator checked also. A bad battery will not hold a charge and a bad alternator will not recharge the battery, (That is the reason to have the battery checked first). Make sure the connections at the battery are clean and tight.
