It was all started when she refuse to start on petrol
first thing came into mind is the fuel pump , but when I inspect through sound fuel pump was working,so 2nd step I checked the fuel lines weather its pumping up till engine block or not & it was, now its bit fishy that why its not starting on petrol ,let me clear, on gas its perfect so no problem in conversion switch so decided to went to Hyundai Town ship Peco road.
They open the fuel pump & found hose leak, let me tell you this small white color wrinkle hose is of pathetic quality and get hard very quickly(as I installed it last year) but no choice
so replace that hose , but ---- no starting
now the guy named Bilal was bit worried and divert his attention toward the CNG conversion switch that may be it was not converting properly but I stooped him on time that its not the fault, anyway next step is to open the injectors, and believe you in me all the 4 injectors were blocked
anyway fault was detected & they start cleaning it with all desi style means injector cleaning spray and tapping
thanks GOd all 4 start working(as new 1 each is 1050) & now she is in perfect condition
, I also changed the fuel filter so fuel came in the system bit cleaned.
Anyway things were pending on it so I decided to give her some time as she looked bit Naraz with me
, & i was embarrassed with her
but Thanks GOD end result was perfect.
