just tried to jumper it and i still cant here it kick on. It seems like it wants to start if i spray starter fluid in the intake but it just stumbles.

 

The fuel pump turns on w/key to on if the fuel check connector is jumpered. And you might have leaky injectors if the engine is flooding. And again, on an S5 the throttle all the way to the floor w/key to start is how you deflood the engine.

A car which starts w/o starter fluid which revs up and then dies quickly thereafter has a likely vacuum leak.

 

ok worked on the car last night and with starter fluid it will start and rev and i can rev it for a total of 5 seconds and then it dies. That was with the fuel pump jumpered. I dont here the fuel pump kicking on.

Just a question. When the fuel comes to the fuel pressure regulator does the regulator give the fuel actual pressure or does it just regulate the pressure the fuel pump makes?
Thanks for continuously helping me out. I just want this thing to start

 

The regulator just bleeds off excess pressure from the pump, it doesn't "add" any extra.

 

ok. i think a friend is going to come help me test the fuel pump this weekend. hopefully i can find out what the issue is. im leaning towards a fuel issue.

 

If you disconnected the return fuel line followed by placing it into a jug followed by jumping the fuel check connector followed by turning the key to on then the jug ought to fill up with fuel. This is a simple test of the pump.

 

ok thanks. ill try that and get back to you tonight. im just changed the injectors so im really hoping is the fuel pump or filter rather than them

 

i just tried the return line and nothing comes out, however fuel will come from the feed line.

 

If the only line disconnected at first was the return line and nothing came out then you appear to have an obstruction of some sort in the fuel system. I would wait for another person to chime in on what exactly that could be. If there truly were an obstruction then air should not be able to pass through the lines thus you could test it from that perspective.

 

Yes the only line disconnected was the return line and nothing came out. Could the issue be the regulator?? When i disconnect the vac line from the regulator it doesnt appear to have fuel in that line. i dont have any idea as to what could be or where it could be blocking it.

 

As far as a vacuum hose is concerned, if it's the one from the fuel pressure regulator control solenoid then that is just a vacuum hose and nothing should be inside it except for air.

 

thats what i figured, i thought i read somewhere that if there was fuel in that vac line then the regulator was faulty. im stumped

 

As suggested, you should be able to blow air or suck air through the system.

And make sure the hoses are connected properly as opposed to the feed line running to where the return lines goes etc.

 

was this with the fuel pump connector jumped AND key to on? Hard to believe you got it out've the main line, and not the return, that would be one HELL of a blockage

 

Hopefully you're not getting owned by your fuel filter. Did you change it, or are you dumb? Just kidding but seriously.

 

If it he has the lines crossed it would make it more possible.

 

Fuel pressure gauge would solve this problem

 

yes it was tried with the jumper.

 

I have not changed the fuel filter, i didnt even think to check i it was bad. But fuel comes through the filter so wouldnt that mean its ok? My buddy is supposed to bring his fuel pressure gauge Saturday so we can test that.

 

Which lines are referring too??

 

This is what my vac lines look like at the solenoids. Could this be any of my issue.

 

Theyre talking about your fuel lines being crossed, ie inlet on the outlet and vice versa

 

Ok i finally had a chance to work on the car for a good solid day. I got the car to were it will try to stumble starts without starter fluid. Found a wire frayed in the gas tank and soldered it up and thats where it started trying better. after taking the intake mani off again i noticed the primary injectors dont have the mixing plate or anything like that in the sockets. Is that my problem. I see the secondary do so im guessing these are really needed?

 

When you say mixing plate are you referring to the diffusers/air bleeds? Some people run their cars without them.

Can you get fuel to flow out the return line now?

yes those are what im talking about. I noticed them not in there but i also noticed the injectors not seated correctly and flush. so i believe they could have been leaking and causing a vac leak. im going to try and get the car back together in the next couple of days.

thanks
