Hi

Recently i changed my fuel pump, and after it was not run rigth...Almost like the fuel system had a lot of crap inside it. But that was cleaned put for 3 monts ago. So, we took out the injectors and clean them with brake cleaner....(did the same last time the car was so poor running., and that worked fine then) but now the car wont start. I can clearly hear the fuel pump running. But no starting.

The starter runs fine, and i allready tried to switch over the relays under the hood.the two relays are the same, so i tried to switch them with each other but that did not help..

The car wil start and run with starting fluid, so compression and spark is fine.
So in my head there is two things that can be wrong... The injectors wont open and close when i turn the key...Or there might be some vacum that are conected wrong.

[




Anyone? Really need some help now....Have not been driving my sporty for 4 wheeks...:(

You need to concentrate on the fuel delivery.
What is the fuel pressure at the rail..?
When was the filer last changed??
Using a stethoscope, do you hear the FI clicking when the engine is cranked.. Philip

The fuel filter was changed 3 months ago.... Also at the same time i had the fuel tank out to clean it. The injectores where cleaned in this proces... (brake cleaner 12v power source and a switch to make them open on close...) I also changed the fuel pump at this time, but this pump only worked for 3 months... it was a "AIRTEX" pump from ebay... But the fuel pump i have no is a OEM style pump from a local car parts shop... looks totally the same...
But im thinking if the vacuum line for the fuel pressure regulator is conected in the wrong wacum port, or not conected at all, will that make the "No start" condition?

:) Thank you :)

Btw: I really never got the chance to messure the fuel pressure at the fuel rail...I was thinking about getting a fuel pressure gauge to mount around the fuel filter, but never got the chance to order it....

FI coils are prone to damage when activated with raw 12vdc

I would be inclined to test their function with a NOID or scope, regardless they require the correct pressure to work properly.... Philip

So you are guessing the injectors are bad? Is there a way to messure them? Like a ohm-meter or something?

But, say the vacum hoose the the fuel pressure regulator is NOT conected. Would a normal start up anyway, or migth this be one reason why my car wont start?

Thanks :)

Ok, thanks

Wondering about the injectors, is it the (OHM) Impedance i should messure?
Sorry for all the question, but im from norway so probably need some good explaining :)

I am interested

  • first that you have adequate fuel pressure (gauged),
  • Then that you have a fuel signal pulse(use a NOID light plugged into the harness)

The chances of all four injectors failing at the same time is pretty slim. Whatever the problem is it's something that would affect all of them.

First, just because you can hear the fuel pump running doesn't mean that it's actually producing flow. I've seen fuel pumps where the impeller has detached from the motor, or the pump output is not connected to the line out of the tank so it's just spraying gas around inside. It's annoying that our Sportages don't have a pressure test port, but what I like to do on such vehicles is the activate the fuel pump and use a stethoscope to listen for flow in the fuel rail, yes you can hear it. The fuel pump can be activated with the key off by running a jumper from the battery hot post to pin 1 of the diagnostic plug, or by removing the fuel pump relay and jumping the feed and load terminals there.

If you can hear fuel flowing in the rail, next check to make sure the injectors are getting power. Turn the key on, and using a multimeter, black lead on a solid ground, check for battery voltage at each injector plug. I'm not sure, but it should be the green wire, or whatever wire is the same color on every plug. If there is no power then you've narrowed it down to an electrical problem. If there is, then you know either all injectors are bad (unlikely) or the ECM is not commanding them open.

If you have fuel flowing through the rail (and even low pressure should allow the engine to start, just not run well) and power to all four injectors, make sure the check engine light comes on with the key in the Run position. If it does, then you know that ECM is getting power (I'm sure you've checked every single fuse already, anyway).

Assuming all that's good, we get into more complicated troubleshooting. The ECM relies on the Camshaft Position Sensor to time the injectors. Some vehicles will run in "limp mode" without the signal, but not all. I don't know about the Sportage.

Hope this helps.

Thank you guys for all help so far :)
Im going to buy a stethospope today, never thought about that. Thanks. :)
About the fuel pressure test port that we dont have, ive been looking for that at. Ebay but never really seem to find the ideal part to use , any suggestions here?

All the fuses plus the few ones under the hood has been checked and found ok.

Really like the NOID tool. I think a remember earlier on ScottyKilmer channel at youtube seeing a simpler version of this tool...hmm. see if i can find it...


Again guys Thank you! I really apreciate it :)

Ok, so i bought a stethoscope the other day, and today i did jump start the fuel pump... conection #1 to + on the battery. And i listen with the end of the stethospope to the fuel rail, and you could clearny hear the fuel was running past. But it nevert stoped....Almost like it was just circulating, not building up any pressure...(Just a tought....) And again, i checked all the fuses inside the car....(Just checking...) But still no start. (But, the car start and runs if i spray alot off starting fluing inn the air intake...(But, thats a NO-NO!)

But if not i have been said it before, i do now: The fuel pump that is installed now is actually for a Mazda 626...(where our engines where in the first place haha), But atleast by looking at the fuel pump it is the same as the earlier i ordered from ebay...Atlest at the looks of it..

But, i do have 2x brand new fuel pump, ordered from ebay that i can try out, these fit my sportage...(The item ad said so...)


Any sugestions? Thanks :)

Hi dj-vega,

If you haven't already, recommend ordering (replacement) Main and Fuel Pump relays & installing as a diagnostic step - rule out the relays are not the cause of your fuel delivery issues.

re: fuel constantly running while jumpered at the diagnostic connector: that is normal / what it is supposed to do: jumpering at the diagnostic connector *** (bypasses) the Fuel Pump relay and supplies direct power to the fuel pump.. ***

*If you can, post a pic of the top of the fuel pump assembly as installed in your Sporty, if it matches here I will check & post the hose connections so we can confirm all lines are installed correctly..

Regards,
GottaCruise

As i promised here is a pic of the top of the fuel pump asembly

Ending up taking it out today, and instal the Ebay pump..
Really did not do any diffrence, but that ok...
Next is computer i guess?, or is there a cheap way to check the fuel injector wire harness?, (Thinking about a 12v led and cranking? )



Here is the computer

Greetings,

Thanks for posting the pic - your fuel pump is different than the one on my Sporty here, will take a look and post back with the setup here & how to trace back from the fuel pump to the motor tomorrow or Friday,

Regards,
GottaCruise

Ok, some updates... My buddy called the local kia shop here in norway...They said the realys and/or the immobilizer to be the problem of the cause.
Searched at the internet about the relays, found a way to check em.

"Take of the Positive (+) terminal, and remove the fuel pump relay.
Then put on the positive terminal to the batery and insert the relay.
Get a friend to take the ignition key to step 2/run, if the relay clicks i should be ok."

Since the PCM/Computer relay is identical to the fuel pump relay i just changed them with each other...So in my head, booth relays should be fine...

But, what about the immobilizer? I really did not think i have one in my car, due to the size of the ignition key...the plastic on the key is like 1x2cm, and there is no way to dismantle it...Thinking about the central locking, that for somewhat reason does not work anymore... Is the immobilizer integrated in the central locking system in anyway? ALL fues as i have seen is good.

So, after what they told at us kia thats the only thing they could think of, due to the car has fuel pressure, compression and spark...

So my buddy, ending up doing some more working in the engine bay.
Taking of the fuelrail, injectors and inspect the colur of the fuel that comes from the fuel tank...(Was a lot of crap in the tank before we cleaned it...last year) And it seemed fine. The injectors are open and close, if you put 12v on.
he also checked the spark plug, on had some oil on it, (allready changed the top cover gasket, but have not got the chance to take out the plugs and temporary clean it....The car has been sitting for almost 6 wheeks now i think..

Evrything is mounted agai as it was earlier, so i would really like some tips... Unfortunatly i starting to loose the motivation to keep going with my sporty...
We have owned it for 3 years now. And have repairs and addons for over 70.000 NOK. (10.000 USD is around 60.000NOK...)

Clutch, Head gasket, rear welding frame, exhaust, catalytic converter, etc...

But, than again....i really love this car...my first baby...(i guess to all been there and miss your first car...)

Is there still no tips?
My baby is stil no starting. But i am able to start it and run is, when i spray starting fluid in the intake...I guess the injectors dont open and closes...So maybe a problem with the ecm? Anything DIY i can do?


Thank you guys ;)

Go here and join free, this is the Official Kia website. After joining go to " Service Info ", then select " model ", " Year ", > G 2.0 DOHC > Engine Control/Fuel System>Fuel Pressure Regulator...and check for pressure...if fuel is flowing without pressure, the fuel pressure regulator may be bad...just a thought...
