Default No start 1995 sportage

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

Test fuel and FI signal..... Philip

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

This may also help, particularly the last 25%.... Philip

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.
