do you have a crank no start, or a no crank no start?

if you have a crank no start as in the engine turns but it won’t fire, it may be flooded try holding the pedal too the floor too disable the injectors and crank the engine and clear the carb cleaner out, if this doesn’t work let it set a few seconds first
also i suggest do a visual inspection of everything first see if there is anything unplugged or out of place.
I have crank no start… i crank the engine with pedal too the floor… i did a visual inspection of everything… I checked the fuel pomp it’s works… I checked the main relay, fuses are ok… but steal no start…
do you have spark going too the plugs? check for spark.
i would also let it sit a while see if that makes a difference too, sometimes the older vehicles don’t have a clear flood mode and you can make flooding worse buy holding the pedal too the floor, usually they do. i have seen cases also where clear flood mode doesn’t kick in with pedal too the floor, so my next suggestion is let it sit now and let it clear out and sit a while maybe that will make a difference.
also if your fuel pump is buzzing it may just be weak though highly unlikely still a good idea too check fuel pressure if you have spark.
it sits about one week…. I’ll check again the spark plug…. last time when I checked were dried but I did not for spark and I did not checked fuel pressure as well… thanks for reply
SORRY FOR MY SPELLING 😀
First, I do not recommend cleaning throttle bodies as a maintenance procedure. It usually causes more problems than it solves. That said, it’s probably flooded. I would recommend you remove the spark plugs and see if they are wet with fuel. If they are, either replace them with NGK or Nippon Denso plugs, or let them dry out along with the cylinders. Once they’re dry, try starting in the same way you have with your foot to the floor on the gas to turn off the fuel injectors.
Good luck and keep us posted.
Modern vehicles have the pcv valve dumping engine blowby into the intake manifold. On my car, after thirty thousand miles, the throttle gets sticky. Let it go awhile and the vehicle becomes difficult to drive at city speeds. A simple wipe out of the area where the throttle plate closes at idle, using a with a shop towel with a little carb cleaner on it, solves the problem.
You have to be careful when doing this because, depending on the emissions package, there will be a few or many tiny vacuum ports in the area of the throttle plate. Plug any of these as a result of your cleaning and have problems.
Also some throttle bodies come with a throttle plate that has a coating on its edge to better seal in the throttle body. Solvents can remove this coating. There’s a product sold that can repair this but I have no knowledge of how well it works or how to do the repair.
One time I decided to get serious about throttle body cleaning and I dunked one in carb cleaner. To do this you have to remove everything that isn’t bare metal. In this case there was a thermostatically controlled idle valve, throttle position sensor, idle switch, and idle control valve. You have to know how to remove, replace and adjust these items.
After a good soak I was surprised at how much black stuff I was able to blow out of the vacuum ports. It makes me wonder how throttle bodies continue to work after thousands of miles.
Well, something is wrong with your vehicle but I’m having a hard time believing the carb cleaner has anything to do with it. Like Eric said, it might have initially been flooded but that stuff evaporates fast. Within minutes it would have been not flooded.
Something else is wrong not related to carb cleaner. You need to retrace what went on while you were doing this work, what else you hit, bumped, had apart or cleaned.
If you only sprayed carb cleaner in the TB and did not remove anything (other than air cleaner) or do anything else before during or after cleaning the TB I suggest you look for wires you may have knocked loose & if that doesn’t turn up anything get the battery tested. They do “suddenly” fail to work when they finally quit. You can get what sounds like the regular amount of juice from it but its not enough amps or voltage to get the starter going fast enough.
I agree with you… today I checked the spark plugs and I have seen no spark…but i think my battery is pretty bad from so many cranks… I ordered an spark tester so I’ll try that again … another problem is I’m not very good mechanic especially the electronic part so it takes me more time to find a car issue and fix it…but i learn from that..
Thaks a lot for the replySORRY FOR MY SPELLING
If the battery is weak, that could be your entire problem. Try charging it up, and then see if you can get a spark.
[quote=”Litto” post=104335]Yes Tomh but a few days ago I couplet another car to my battery and still no start…[/quote]
Coupling or jumping a battery often will not work if the battery being jumped is bad or too low. Get the same guy to let you put his battery in your car to see if it starts. Then you can take it out while its running and put yours in to see if it takes a charge. Like you said maybe you just depleted it trying to crank so much not knowing you should wait for the vapors to disperse.
