I need advice please, I just converted my Toyota Picnic to CNG, now am finding it difficulty to start the car in the morning, different mechanic has done different things yet no solution, I have gone to the CNG people and they said the CNG option can not affect the car starting,. I don't want to remove the CNG yet because it has reduced my weekly fuel cost .
I don't know if any one here had a similar experience?

Your battery or alternator is weak

Bring it to my shrine let me douse it with the blood of a Benue state virgin

Kickstarter, coil, nozzle and rail, plugs, fuel pump casing ,airfilter.

Always start your car with fuel in the morning as long as it is injector system.
Secondly go and get grade a iridium spark plugs

Like someone said battery or alternator may be weak. Don’t rule out faulty kick starter

Hard starting most times is due to .....

It's in the key starter or the ignition.. tell them to put something called a quick start.. I can't remember the name but I can link you to the mechanic

Na lie, no be all those things... It has to do with the CNG setup.
CNG nozzle, pressure and the gas combustion.

If I may ask before the CNG conversation does it start normally?
Was is after the conversation the problem started?

do you experience that before converting to CNG, did it happen immediately after converting to CNG, is your check engine light on? scan the car, it might be a sensor, check your Crankshaft Position Sensor, Camshaft Position Sensor, Engine Coolant Temperature Sensor, Fuel Pressure/Rail Sensors, scanning will give you a better result, you don't need a sophisticated scanner, those TEMU 25,000 OBDII scanner can also do the job

Try starting it on fuel first, if it continues even with that, then rule out CNG calibration defects.
Get a mechanic to clean up your cam shaft sensor

The problem is YOU. Why will you covert your car to cng without even having knowledge how the cng works. Don’t start with cng in morning only petrol before switching back to cng. You are going to wear your car engine soon if care not taking.

If it happens only in the morning, then I suspect 'cold start sensor'

I guess they tinkered with it the day they were fixing your CNG. You don't need to buy a new one , let them fix that one well

May that picnic vehicle that has turned your night mare , not explode and take your life, Amen 🙏

I was told that the CNG does not start the car but always pick up after some second depends on the engine temperature

Start your car with petrol first before switching over to CNG, if situation persist, get a good scanner and scan to find the error code

i dont advice CNG it weakens your engine over time due to dry combustion

Let me know when this is resolved, please.

Cold start sensor! You are right. My car once had that problem.

Your CNG needs to start with petrol first. Go to a mechanic workshop that knows what they are doing. Leave all these "Kazeems" mechanics.

Always make sure you have enough fuel in the morning to start the car....
It is better to start with fuel before switching over to CNG, that's how I run my Spider

Take it back to default mode

You don't know what you are saying

Prime the pump before you start in the morning by turning the keys to ACC twice before starting.

this will let you know if you are losing fuel pressure overnight.

If that fixed it and the had worked around the injector rails you may have a fuel leak that might turn into a fire one day
