My Corolla altis 1.6 2017. It’s cranking but doesn’t start

[pwuser170599162366]

Battery is new. According to the mechanic “gaari mein pulse nae arai” card saaf karwaya, immobilizer ki reprogram karwaya, no tracker in car. Koi lights show nae horai. But yes self maarney k baad if gaari start nae hui to throttle sey ya uski side sey awaaz ati hai. Second throttle body bi change kar k dekho issue gaya nae. Obd scanner bilkul perfect health bataraha no codes.

fuel pump pressure and health checked ?

What kind of moronic mechanic have you visited? Its a pretty straight forward case.

After checking for power and grounds is the ecu registering engine rpm when cranking engine? If not then test the crank and cam sensor for working.

Without crank sensor activity there will be no ecu workings.

Poolss nai aaraha is not a good answer from a mechanic.

[pwuser170599162366]

You are absoulutely right. I have check for those sensors but they are working fine. Can u suggest me a good mechanic,they are like k we should change the card and i was like what the fuck you are talking about. I might have some videos what car is doing and share it too

[pwuser170599162366]

@hash4u health is showing no error or anything, even when car is idle.

[pwuser170599162366]

Also if anyone can suggest me a good mechanic

Visit Irshad Ahmed at Jameel Autos, Shahrah-e-Qaideen. 0300 2237538. It seems like you might have nonexistent or intermittent crank sensor signal to the ECU, if your fuel and ignition are confirmed to be good.

You didn't need to replace any of those things that you did. How is the "card" "cleaned?" Don't let random idiots poke around inside your ECU.

[hash4u]

With a tooth brush and spirit

[Xulfiqar]

How did you test that they are working?

[Xulfiqar]

Fateha on ecu!

Btw, never heard of ecu champi paslish! Is this a new fangled job?

[pwuser162557941033]

Another thing to check is whether you have a check engine light visible on the dash when the key is in the ignition position with the engine off.

I spotted this anomaly when my 2003 Corolla was doing a similar crank no start thing and left a family member stranded at a petrol station out of the blue, even though it got there perfectly fine. The ECU fuse, in the under-hood fuse box, was corroded and making random, intermittent contact.

Replaced it, and the check engine light was visible on the dash again with the key in the ignition position. Cranked it, and engine started up instantly.

Btw, never heard of ecu champi paslish! Is this a new fangled job?

I would've thought that it makes some sense that they'd clean the harness connectors, but never the actual PCB. If that's what they're doing, it's madness. But I'm not surprised by Pakistani antics anymore.

Idle means engine running at idle speed

In auto repair the term used should be

KOER
KOEO

Key on engine running
Key on engine off

Please use correct terms to not confuse others.
