Your timing belt/chain may have jumped a tooth. Have someone crank the engine while you watch the easy the engine belts as they turn. TheThey should rotate in sync. Then pull#1 plug and check for timing Alignment for top dead center. It's really helpful to use repair manual for locating the timing marks to do this procedure

SOURCE: car will not jump start

Check battery voltage. If volts are very low, put on charger. In many cases, you can't jump through a really dead battery... not enough voltage gets through to computer etc to make systems operate.
Battery may be used up... if it will not take a charge, replace it and check charging system before driving. PS: use a charger to charge battery. If it is very low, you candamage charging system in other vehicle. Also,,, You cleaned terminals already RIGHT???

SOURCE: vw corrado g60, wont start.

i used to have a golf g60 and had a similar problem, with mine it was the coil lead.
but it could be a number of things? i sold mine due to the amount of problems i had with it aswell !
if the fuel is still in the cylinder then it has to be an electrical problem as its not igniting. are you getting a spark from the plugs? leave one out and get some one to turn the engine and see if the plug is sparking. if its not then its either the coil, rotor arm, dizzy cap or leads.

with the battery fully charged try scraping the positive over the terminal on the battery and see if it sparks like a draw is sucking out amps if theres no draw on the battery it wont spark at all (good) if it sparks (bad) you have something grounded and killing your battery.. gl

Car wont start when it gets cold out


You don't say whether it is petrol or diesel engined or whether the engine is cranking fine but won't fire.

Certainly an engine must crank quick enough but even then if it is the best diesel engine ever made it is unlikely to start below freezing without an artificial starting aid. Such an aid is already installed but must be in good condition. Heater plugs do fail sometimes or get tired and lazy so they need checking and sometimes the timer relay fails to switch them on. Good injector spray patterns are also needed for good starting.

Petrol engines need enrichment of the fuel/air mixture for cold starting and a very good spark at the plugs. Worn spark plugs is the most common cause of poor starting and if the ECU isn't getting the right information about temperature it will be unable to make the correct fuel adjustments.
A good injector spray pattern is also important.

Lots to think about...

Automatic choke not working


There is no choke on a 94 Camry. Might you have posted in the wrong category?

The extra petrol required for a cold start on this car is supplied by the injectors as controlled by the car's computer. If you experience hard starting and hesitant running when cold, it is most likely that you have a

- failed enginetemperature sensor
- malfunctioning fuel pressure regulator or fuel pump
- faulty cold start injector (3VZ engine only)
- carbon tracks on distributor or rotor surfaces

Sometimes my car starts and sometimes it does not. everything is on in my car but engine won"t turn over. i let it sit for a long period of time and it starts. what could be worg with it?


The first thing I'd suspect would be the distributor cap & rotor, but my 2003 PT Cruiser manual says:

1 - Inspect Fuel Injector Pressure Regulator --- Faulty Fuel Injector Pressure Regulator.
2 - Inspect Carburetor Float --- Faulty Choke Float.
3 - Inspect Choke Pulloff --- Faulty Choke Pulloff.
4 - Inspect Choke Thermostat --- Stuck or Improperly Functioning Choke Thermostat.
5 - Inspect Fuel Injector Cold Start Valve --- Damaged or Faulty Cold Start Valve.
6 - Inspect Spark Plugs --- Fouled Spark Plugs.
7 - Inspect Relay - Fuel Pump --- Faulty Fuel Pump Relay.
8 - Inspect PCV Valve --- Plugged or Damaged PCV Valve.
9 - Inspect Carburetor --- Choke Not Operating.

My 1996 Toyota Camry is having starting problem. It turns over but won't start unless I floor the gas pedal. Once she's running, she runs like a charm. She starts right up when I'm driving running errands....


all cars have automatic choke system when the engine is cold the choke is automaticall at onn

you must have noticed that when the car was ok and was cold started it use to stay at high rpm and after its warm the rpm reduces

so get your choke settings checked or needs some part to change in the choke system

1975 Datsun (ie. mechanical fuel pump). Carburettor, electrics (inc. battery all good) fuel strainer all good. On cold start engine needs to be cranked several times. Warm start is invariably immediate. ...


Carburated vehicles ether have an automatic choke, or the very old ones, a hand choke. Yours has an automatic choke. The starting problem likely is a problem with the choke. The problem is almost certainly not the fuel pump.To set the automatic choke, push the accelerator to the floor, and RELEASE. Then start the engine just like you would a fuel injected vehicle. If this doesn't solve the problem, then the automatic choke needs to be repaired.

Will not start on hot day's in the sun.[engine cranks normal]


The normal reason why a hot engine doesn't start is the choke. Your fancy new range rover will have a computer controlled choke that will be activiated by a temperature sensor. maybe this has failed or is disconnected
In my ancient range rover I have a manual choke but essentially the same engine. I know that if the motor is hot I can't start it with the choke on.
The way the choke works is it restricts the airflow into the engine so that there is a richer fuel / air mixture which is needed for a cold start. If the engine is hot and the choke comes on the engiine floods with petrol and there isn't enough oxygen for it too ignite in the cylinders. To start a flooded engine you have to open the choke and crank the motor without pressing the accelerator. This pumps out the petrol vapour and eventually it will fire and start. If the computer thinks it is cold because of a disconnected or faulty sensor it will put on the choke whenever you try and start and the engine will flood.
I think a vapour lock is unlikely unless you driving in extremely hot weather (above 40 degrees celsius).
