HELP! Wacka wacka but no puff (car doesn't start)

I used the car Wednesday and it worked OK. Thursday it didn't start, I just took my fiance's. Today I'm troubleshooting and this is what I got so far:

Car's engine turns when ignition is switched to start position (and makes wacka wacka) but it makes a very weak puff and dies. Thought it wasn't getting enough gas, maybe fuel filter clogged. Walk to auto parts store, got fuel filter, came back, changed it. No improvement.

I disconnected fuel filter again, it squirted some fuel out so, fuel pump is OK. Connected it back, no improvement.

I check the OBDII codes and got this list:

P0003 - Fuel Volume Regulator Control Circuit Low
P0200 - Fuel Injector CIrcuit Malfunction
P0013 - Actuator Circuit Bank 1

P2815 - Haven't found what it is.
P2900 - No Idea
P007e - No clue

I'm gonna go check the fuses now.

/sad rube' off

P2815 - you have gremlins.

actually, if there is such a thing, maybe your fuel flow sensor needs cleaning?

Pump is getting weak it sounds. A fuel injector requires somewhere between 50-80 psi if I remember correctly. Sometimes they will pump but shroud enough force. Borrow a pressure gauge and work from there. Could also he a failing pressure regulator. Good luck.

What type car. I had a Ford that died with symptoms like that. Ended up jogging on a desolate stretch of US27 to the glades to a fish camp, leaving the family at the car. It was a rental and they sent a tow truck that brought us into Ft Lauderdale. Turns out, there was a reset button for the fuel pump in the trunk and that is all it took.

I also have some symptoms bothering for a few weeks. Starting up was pretty rough running for a minute in the mornings. More rough on cold temps. I added fuel injector cleaner and it got better for a few days. Changed air filter too, tho it looked clean. I do have the haynes book for it... just can't find on what box I packed it (I'm in the middle of a move).

Sometimes it would get really weak when accelerating... it would only accelerate *very* slowly.

I'll research the fuel pump possibility a little further...

my car does that on cold days and it's because the MAF sensor needs to be cleaned of carbon deposit. It's a known fault on my car.

When a Hyundai randomly doesn't start, look at the Crankshaft Position Sensor. I also suggest joining elantraclub.com and elantraxd.com forums. Yeah, not Accent specific, but they have a lot of Hyundai knowledge, especially Bobzilla on ElantraXD- he has an Accent of about the same age I think.

Also, you can get to Hyundai's tech manuals online at HyundaiTechInfo.com. It's free to register and use. If you have any problems with it, ElantraClub.com has a common membership ID and password you can use.

I found the Haynes book yay! Too late/dark/cold to do anything now tho, will continue tomorrow. I'm just undecided as per what to look into first:

1) Crackshaft position sensor
2) Fuel Pump
3) Fuel pressure regulator

Crankshaft sounds more likey as it would explain the rough starts. But then, it was only rough when starting so I could probably rule that one out. I had replaced one of those on a jeep cherokee. That thing really jumps like a rodeo bull if the sensor is out of whack.

Fuel Pump & regulator sounds tricky... how to know which one is the culprit? But the idea of getting a new tool (fuel gauge) sounds fun.

PS: Fuel pump seems to be 100 bucks a pop... I'll hate myself if I replace that and is not the culprit.

I also had a crankshaft position sensor go out on a Cherokee. It caused random failures to start. Recently had a fuel pump go out on my Saab, it just flat out failed to start. If you're sure you have spark, and it sounds 'normal' when trying, it certainly sounds fuel related, especially considering the nature of the codes.

All of your codes are fuel related, I would look at the fuel pump/regulator first.

BTW, on Car Talk just now someone had a similar issue, though theirs was intermittent, and on a Civic. They suggested replacing the fuel filter relay.

Here's a second on the crankshaft position sensor. I had one fail on a Hyundai accent but it was really easy to replace however my computer threw a code for bad crankshaft position sensor.

Oh wait. This is Ruben's car, isn't it?

Fuel pump is commonly in the fuel tank (less chance of the fire department showing up that way), and replacing that would mean taking the kitchen table out to the garage. Unless your family likes the smell of gasoline while they eat.

OK... I replaced the fuel pump. It was a PIA because the pump and gas level gauge is one unit. Haynes tells you where it is (under back seat) but not how to take it apart. I had to take the seat off, unplug hoses, and take the assembly out of the car... let the gas drip/dry and off to the kitchen table where I spent 2 hours trying to figure it out. It was all plastic with a gazillion clips. I finally got the new fuel pump into the assembly and went back to the car. When the assembly is out, you have a 5 inch hole that goes directly into the tank, car's cabin was full of fumes... Rube got dizzy but finished the job.

After fuel pump was replaced it took quite a few cranks to get it going. Gess it was the air on the lines. It finally started. Is still running kind of weak, specially during acceleration. I put the fill it up with expensive gas and put fuel injector cleaner on it. Tomorrow I'm gonna reset the codes, take it for a longer spin and re-read any codes still there.

If I put in on neutral and try to accelerate it acts like is gonna die. :\ But at least is running (slowly).

Be thankful you have that access panel. Many cars (my 1999 Saab 9-3 included) do not, and you have to drop the tank.

See if the vent to the fuel tank is clogged(old french fries,condoms,taco wrappers).
You did change the fuel filter,right?Pressure regulator to the fuel injection?Former ex-s boyfriend pee in the gas tank last night and spoil fuel?

*Please refer to the damn Haynes first for vent/pressure regulator location before you bother us again then we'll talk.

No. If they are clogged, you need a new one.
