    Exclamation Corolla GLi 2008 startup problem

    The car in question belongs to a friend. 100K Km on the clock with CNG, mostly driven on CNG. It does not start easily after being stalled for 1-2 hours. Need to manually switch to CNG and Petrol alternatively and giving long self start tries, and it eventually starts. Runs fine on Petrol and CNG otherwise.

    Another option to start is by putting a few drops of petrol in the opening of pipe leading from Valve cover to the air filter (marked in the picture). PS. The picture is not of the car in question, but a randomly picked picture from the internet.

    Once hot, the car starts fine, but cold starts are the basic problem.

    Toyota 3S mechanics first advised replacement of injectors. When argued that in case of bad injectors, the car should demonstrate missing while driving as well. Then they advised replacement of fuel pump. This shook our confidence and we decided to call for experts' help on this forum.

    Please help!

    Keep your friends close but your enemies closer...

    Did you check your injectors and Fuel Pump? If Injectors are leaking they will drop petrol in the cylinders and also the fuel pressure rail will lose its pressure.

    You can check if injectors are leaking or not by removing injectors but keep them with the Fuel Rail and power the Fuel pump only as the pressure will raise you can spot the leaking injectors.

    Also check to see if your fuel rail is holding enough pressure after car is switched off.

    Check Emulator, Connect the injectors directly and test.

    the starting problem can be either electric or related to the sparks at the right timming in the cylinders
    or
    it can be a feul related problem means the feul is not being fed properly into the cylinders, which can be injectors or other feul injection problem.
    but
    in your case all i can say for now is there are two types of cng kits available. one for the older simpler technology cars. these kits are cheaper
    the second type of kits are more expensive ones which are automatic and specifically designed for feul injection engines.
    the simple kit can also be installed in a feul injection car but it will not run properly and will keep on giving problems like the ones you mentioned in your post.
    for now i would only suggest you to check if your cng kit is the electronic one or is it the simple one. there are people who install cheaper simple kits in there feul injection cars just because they cost much less and these people dont have the know how of the technicalities.
    the last thing i would suggest, and this is just a suggestion, if it is possible for you to run your car only on gasoline and dont use cng. i know petrol is expensive. but the problem here is these engines are designed for petrol as a feul and when we use other options as feul these sensitive feul injection engines can give problems and sometimes lead to much more expensive repaires. thats just a suggestion. i know this is not easy as feul prices are sky high. but cng is already going scarse and it will not be available in a short period of time

    check for advancer / emulator for its function also in morning before cranking engine check if there is any fuel smell in engine bay.

    what is battery & plug condition.

    1) First of all, Check the spark Plugs. They seem to be the initial problem. Condition, Age, Gapping. k-16r-u11 is the denso code for the 2nz-fe Engine.

    2) If the injectors/Advancer etc would have been trouble makers the car wouldnt be running fine or either petrol or CNG.

    3) The ignition coils could also be trouble makers as you said the car is driven on CNG mostly. But as there isnt missing i doubt coils are a issue in your case.

    4) If you car cranking fine or does it slip?
    Get over the fact that Xli lacks power windows, Its an Xli because it lacks thoose features or else it would be a Gli or an Altis if had all the goodies.

    in low temperature these days the advancer / emulators are failing due to dry solders over the circuit boards (moisture over the circuit boards is observed)

    Mostly cold start problem observed because of incorrect valve seating and a weak ignition system.Some time, if cold start system not functioning properly then same thing could be happened.
    However,first of all replace air and fuel filter,they might be clogged up.
    Never loose hope in life,every step gives u something.

    ^
    We dont have proper equipment to check rail pressure desi way is to when car is witched off give it 20 mins and ask your mechanic to lose the fuel pipe connected to your injector rail and see if the rail got some pressure in it.

    BTW did you install a relay so when your car switches to CNG the Fuel Pump stops working? As without it when ever your car is on CNG Fuel pump will be pressurizing the fuel rail and injectors all the time this might cause your fuel pump or injectors to go faulty or Fuel pressure regulator.

    Used Fuel pumps are tricky to try but you can get XLI One for around 1200 Rs in a good condition to test.

    can any tell that what is the procedure to check FUEL PUMP as i also faced similar problem in 2007 corolla

    & same issue, 3 dealers have no final point, some says that injectors r problem, soem mechanics says that check from cng guy some says fuel pump is weak

    when i took to cng mech.( he told that advancer/emulator is issue, that problem will sort with expense of 8k)

    while dealers 7 petrol mech. told that problem with fuel pump

    IS THERE ANY WAY TO CHECK THAT FUEL PUMP IS WORKING PROPERLY ?

    problem is this:
    its 2007 xli

    Stats are such as Local: 115 to 120 km on 55kg cylinder( means iin almost 8 kg gas)

    we have shown to some mechanics but mystery still not solved car is very smooth & ok on cng but on petrol causing lots of jerking, also seems "ghutee hoee", even with full accelerator pressing, car hardly move, rpm does not increase, this stuation causing problem specially when car satnds on traffic signal & ur car give such performance,


    u know khi traffic, they start horning u like u come from mars or jupiter, so in such cases no choice other than to put it on cng

    please help me as this issue causing problem specially when families sitting with u , any idea

    CURRENTLY BCOZ OF this we can only drive it in cng, mostly my cousin drive with family so we cannot take risk in city like khi

    but nowadays cng availability is issue.

    i wanna it perfect on petrol too.

    i dont knwo 1 other small issue is related to this or not(car starts with a littel delay, not too much but little delay, that point is used as a base by mechanics that FUEL PUMP is problem)

    PLEASE TELL ME PROCEDURE TO CHECK SEPERATELY PERFORMANCE OF FUEL PUMP
