Dear sir
I have Hyundai accent 2010 1600cc. The timing belt was broken and it's broke 2 valves after I replaced it the car stated normally after about 3 to 5 minutes the engine was showdown by itself. Then I tried to started the engine but the engine can't stated ( die) I used the OBDII show P0340 I replaced the sensor can't start too I checked all the wiring and the voltages every thing looks fine. What should I do ? Please advise,
kind regards

 

The code is providing some direction, however, we need to verify if ,

we have spark available
do we have fuel available , remove one spark plug and see if it is wet or dry.

If wet,could be fuel question (quality) or no spark condition
If dry, no fuel condition
Which do you have?

 

I checked it
got fuel and spark

 

Because I have found this to be a problem before,
It sounds crazy, but unplug the alternator and see if it makes any difference and starts.

 

I have disconnected the alternator it's same nothing change still give P0340
and the engine can't start

 

I believe a compression test is the next course of action, so you know where you stand, can you do that?
