Why won't my car start with a jump?
Hi,Possibly you did it wrong or maybe the car has a fault that can't be cured by jumping it. Typical faults CAUSED by jump starting are blown fuses or worst case, blown ECU's. What jump starting CAN'T fix broken starter, broken I injection system etc.To jump start.1 pick a suitable candidate to jump from.Be sure the car actually needs a jumpMake sure jump leads are serviceableWhen connecting, connect earth to earth and pos to pos….. obvious I know but you'd be amazed how many people don't!DO NOT just connect leads and try to start….another reason things go wrong.With car that will provide the jump running connect the POS to POS and make sure it's a good connection.Connect the NEG again making sure a good connection. Reason NEG is connected second is to minimise shorts.A word on modern cars with battery monitoring . Some cars DO NOT respond well to connecting batteries direct. They might want neg connections made to specific points. Always check.Once cars are connected go have a brew. Tea for Brits, coffee for Americans. Leave the jumping car running a good 10 minutes before trying to start. The idea is that you're using battery power, not just the leads…this is another cause of failure.Try to start vehicle.If it turns over properly but won't catch then there may be a problem.If it doesn't even try to turn over then the problem may not be a flat battery.If it starts CAREFULLY remove jump leads pos first.Once running take car for a drive. DO NOT leave it running at idle to charge battery…. If batt is an AGM batt and it's flat the alternator will get very hot charging it. If you just leave it idling you may damage alternator. Drive it, that way you'll stress alternator less.Provided everything went all right, get the car checked for parasitic loads…. They are things that cause batts to discharge and require a jump. Typical offenders are boot light switches, glove box switches, ECU's etc.Simple rule. 3 things make a batt go flat: The batt is knackered so needs replacing. The alternator isn't charging. Something's been left ON. It will only ever be one of those three things as a rule. Hope this helps.Finally if car won't start after jump and you suspect jump caused it. Check fuses as some cars are sensitive. Fusible links (not the same thing) and dash lights in case an ecu has been damaged.
What is the reason a car won't start after running out of gas and putting gas in it again?
Fuel system needs bleeding of fuel to remove air ingested when U ran out if gasThe fuel pump will now be pumping fuel, but you'll have to crack each injector fuel pipe connection and allow fuel to flow to allow air to escape. When fuel flows solid from each injector pipe without bubbles, it's bled.
My car won't start, but if I let it sit for a few minutes it starts, why?
Does the car not crank over at all or cranks over but won't start? Year, make and model? mileage? any recent repair work done? More info needed. An intermittent no-crank situation could be caused by a bad or misadjusted ignition or neutral safety switch or starter "heat-soak" issues although heat soak usually lasts for an hour or more to cool down the starter. Engine heat soaks into the starter and expands the armature which binds it up and won't allow the starter to turn until it cools down....common issue on some vehicles. If it cranks over but won't start, you could have other issues like low fuel pressure, bad pump, pressure regulator, faulty relay, etc.. or vapor lock on an older vehicle without fuel injection and hot temperatures. Edit: All cars have a neutral safety switch to prevent starting in gear....you can only start in Park or Neutral or with the clutch pushed in for manual trans. For auto trans...You can try wiggling the shifter a little when trying to start or try starting in Neutral....if that helps, the NS switch is bad or needs adjustment. For manual trans...move the cutch pedal a little or test switch with testlight. If not , you could have problems with the ignition switch temporarily not working/making contact...adjustment or going bad...or have issues with a bad starter solenoid or wiring issue.
Car won't start, burning smell?
I tried to start my car today, but it wouldn't start. Tried to start the ignition, and I could hear the car try to start, but it wouldn't. The battery light was on, so I think the battery must be dead. But there was a burning smell too. What does the burning smell mean?
Car wont start but starts a few hours later?
so a few weeks ago my car's engine started turning over slowly and taking a longer time to start.. then the car diied, we tried charging and jump starting with no luck, took it to a shop paid 450 dollars to fix.. (replaced the starter) then a few days later we had trouble starting the car again.. it made a sound when i started it so i took it to another shop that covered the warranty of the first replaced starter, they then put another starter in.. now 2 days ago my car died and wouldnt start..doesnt make any sound when it turns over, the lights and radio turn on and stay on when i turn the key, it just wont turn over.. so we left the car, a few hours later when we came back to leave a note on it so it wouldnt get towed, it magically started we took it back to the shop to have it looked at and they said nothing was wrong with it... now today the car once again just wont start.. doesnt make a click or any sound when i turn the key, lights just turn on but car wont start..
Car wont start, it turns but wont catch, smells like gas?
The most common reason a car will crank but not start and you smell gas is you flooded it. Too much gas to the engine causes too rich a fuel mixture and the fuel won't ignite. If you have throttle body injection (it looks kinda like a carburetor but sprays fuel down into the intake manifold) then press the gas all the way to the floor, hold it down and try to start. If it is a fuel injected engine then crank the engine without touching the gas pedal. If neither of these work then let the car sit overnight and then try to start it as you normally would. One thing you can easily check while you are waiting is if the spark plugs are getting any fire. Pull the plug wire off any spark plug and lay it on the engine close to some bare metal. Then crank the engine. If it is firing right you should get a nice blue spark and a popping noise from the end of the plug wire. If it doesn't fire or the spark is weak (yellow instead of blue) then you have a problem in your electrical firing system and will probably need a mechanic to diagnose and fix it. Another common problem on these late model Fords is they have rubber timing belts instead of steel chains and they have to be replaced about every 20,000 miles. The belt gets old and stretches causing the engine to get out of time. If it's far enough out of time your engine won't fire at the right time and you get raw gas fumes out the exhaust or as blow back through the carburetor. On older model cars it's easy to check the timing on your engine. But these later model ones have electronic ignitions or coil packs and I have no idea how to check the timing on them. You will have to get a mechanic to diagnose and fix it. I hope you just flooded it and it starts up easy. Good luck.
