Hey all, I'm new obviously. My girlfriend has the above. The motor was replaced once, less than a year ago. Though not listed in recall for the theta, she had a bad engine.

Here we are now. It was cranking but not starting. I checked the fuel pump/injector fuses and swapped for a known good on each. And then pulled and inspected the relay. And then tested it.

And then pulled the back seat so I could hear the **** fuel pump priming.

And then a buddy stopped and we checked the timing belt for tension or signs of slippage.

And then he hopped in and I held down the throttle and it puffed smoke and fired up. All right before he tried running me over. Good thing I'm nimble.

Be the water.

Anyway. It's started there after without issue. But I don't have a why or a what.

This vehicle is like 15 years too new and the wrong nationality for me. So there are some things I'm just not going to know about. So please don't feel bad explaining **** to me like I'm 5. I actually encourage it.

is the car a touring(wagon)? if not, then the engine is a 1.8. unless it is a transplant, there never was a 2.4 in the elantra. also, the 1.8 has a timing chain, and even if it did have a timing belt, there would be a cover on it that would be kinda difficult to get to. did you mean serpentine?

No I meant the touring with the 2.4.

It very well could have been the serp. Passenger side under a cover with 4 10mm. He thought it may be slipping. I didn't particularly agree.

Flooding explains the exhaust, but not the cause of the no start.

I do think it is fuel related. But I'm not sure why. Maybe the fuel pressure gauge I'm getting for the bronco will fit the rail on hers.

Flooding explains both.

How'd the engine flood on the first crank attempt? It didn't ignite.

How did something with no spark gain spark without me changing anything?

So let's say it flooded on the first crank. That's the what. What's the why?

It didn't ignite because it was flooded.

How do you know it had NO spark?

May have been flooded before being cranked,


That's the what. What's the why?
Leaky fuel injectors.....bad regulator...

Would the injectors leak sporadically then? I ask because it fired right up at 645 this morning. I checked so I could leave her the bronco if necessary. To test, I would have to put a gauge on it and measure the static pressure and then let it sit for a day and check again after? Without energizing the pump.

I can't run and do anything now as I'm 2 states away from the car, but it would be nice to look at it this weekend while the paint is drying on my core support

Also, I'm assuming about the spark. I'm assuming there was no ignition because there was no fire. I'll have to ground a wire and check each wire.

Without a coil and a distributor and a timing light, grounding out a wire and sticking it into the coil packs (???) And looking for the arc, there's no simpler or less risky of a method, correct?

I'm not afraid of the car or messing with it.

I've ripped apart the front and rear and I'm doing the rad support, timing and water pump on the truck this weekend . I can do diag as well. It's like I said, the vehicle is too new for me to know tricks for diag. Nor am I an auto mechanic.

This is what I know.....A flooded engine may or may not kick during cranking. When you went to clear flood mode, WOT, the PCM will not excite the injectors and there's a full gulp of fresh air. At this point the vehicle started and you seen the effects of it's 'clearing it's throat' with the gases being expelled out the tail pipe.
Was it flooded....I can't say for sure but it did EXACTLY what I've seen from flooded engines in the past. The pedal to the metal clear flood mode worked in your case.....in severely flooded engines the plugs may be so fouled it will not start even when the system is forced into clear flood.
I wouldn't condemn the secondary ignition due to it's not firing when flooded.

So, in order to test for a flood, I can pull the plugs the next time it doesn't start and see if they are wet or there is evidence of fuel pooling?

If wet, we have our culprit. If dry, I will know the gremlin is elsewhere.

Sound somewhat accurate?
