***03 GTI LE RFI NO Start got spark, compression, fuel... WTH***

[aaajaws]

Bought a used 2003 GTI LE RFI 215 hours. was told he swapped alot of parts out to get running in the end he says he did but it sucked water in cylinders because he had a gasket on backwards . Anyway my problem now

Wont start sputtered couple times but no start .......... not getting fuel ??

No reply is to simple to try, yes I put 3 gallons of gas in it and it has plenty of oil

1) Good solid newer battery + Keep her on a 2amp charger when working on it as well

2) Good Spark, New plugs , gapped .o22in, new boot ends , I can see a good blue spark when when both plugs are out and grounded

3) Compression : both plugs out I have 125 psi on both cylinders

Can crank and crank but never smell fuel on the plugs ......?

4) Fuel so far I can hear the pump kick in for 2 secs every time I put the DESS on , on the fuel line left side ( I will call it a schrader valve) green cap I can depress with a screw driver and gas does shoot out .

4a) it does if I leave the key in 4 beeps ( which i read is normal) but the dash clears and then reboots ???

I did shoot some starter fluid in #1 cyl a couple times with no luck.

That's it so far , nearest service center is 1 1/2 hours away beside the fact that I love figuring it out ( or with others help ) and hate paying "stealer" rates.

Help is all I can say, I have a volt meter and know how to use it, I would much rather buy a new tool to help diag then pay the dealer.

Any and all help truly appreciated Not afraid to make a donation to your favorite charity ( beer money ) if we can figure it out. PS in the way North near Canada so freezing temps not far away

Thanks
Jaws

If he swapped parts... you don't know what you have. Timing could be off, could have too much clearance on the rotary valve, wrong rotary valve. You don't want a ski some clown worked on you need to verify everything. Download the repair manual and start checking things If I had a 787 with 125 PSI reading on an accurate Compression Tester I'd do a top end for certain... no question.

Question - Are you giving the ski throttle when you are trying to start it? Did you check fuel pressure.

I"d start from scratch and begin with a fuel pressure test. Next replace the fuel filters in the tank. Timing could be off but you need to pull the rotary valve anyway and have a look. Check the clearance. Good Luck

Did not have WOT on a compression check so will redo that just read that is needed so should boost PSI

no throttle when trying to start most of the time did try a couple 1/4 throttles .... my understanding wide open kills spark and fuel on RFI machines

Yes I have a feeling something minor but not installed correctly on this machine. He did say he messed with the rotary valve

Thanks for the reply

just did a WOT 138 PSI which should be good enough ??

138 is a lot better than 125. LOL You got fire and that is a good thing. From where you are now I'd check fuel pressure and the fuel regulator. A good regulator will hold the fuel pressure for a time after the pump shuts off. Don't let a pressure drop scare you though. I had one drop all the way to 20psi in about 15 seconds and the ski ran fine. Of course I replaced it.

I read that sometimes the Throttle position sensor and the air pressure sensor plugs get switched so you might want to check that. Lot of times the TPS has red or orange tape on it.

Run the component checks from the manual. TPS, Air Pressure sensor, Crank position sensor, Rave Solenoid, injectors, I think the one inside the air box is an air temperature sensor. There are 3 in that small area. There is a misprint in the manual with regard to one of the checks. it sends you to an incorrect pin on the plug. I don't remember which one it is but they send you to PIN "1" and the correct pin is "11". If you do it there way it will show an open line. Follow the color of the wires and take your time. Good Luck.

I have not had a lot of success with the Candoo programmer on the RFI skis so don't go thinking you need to spend $400. Good Luck !!

Well went to the auto parts store rental tool and got the fuel pressure gauge set none of the adapters fit , tried at the quick disconnect at the fuel rail and the schrader valve so have to try something else. I read #1 is where you take the reading but how the hell do you connect there ?

 

[aaajaws]

OK where do you get one of these ?

 

[etemplet]

Hmmmm.... I had a GTI LE RFI that had a TEE in the line with a cap on it. I just purchased another fuel line and put Tee in there with a schrader valve.. That way I can watch the pressure while the engine is running. Here is your fuel pump module and filters.

 

[aaajaws]

I do have this but none of the adapters fit . Gonna have to find one that does this come from the pump to the quick disconnect of the fuel rail. i see your above picture of the pump and filter I should probably go ahead and order a filter anyway

OK change direction last owner said he put all kinds of parts blah blah blah but gasket was backwards on the large black pipe ( head pipe ) and when he got it running good son took it out an it flooded the block.

Went to try and spray some starter fluid directly with qtr throttle look at the hull that there is no suction its spraying out oil/ possibly water, I dont smell any gas in it either ?? what would cause this blow back ?

No luck with direct shots of starter fluid .... TIMING ??


Or is there still a fair amount of water /oil in the bottom of the block ....how could I drain I would think it would have all came out of the spark plug wholes by now while cranking with them removed ? I have never hooked it up to a hose while trying to crank since it has been at my house .

Maybe I should remove plugs and see if it comes out plug holes or still through the arrester housing / throttle-body

Pull the spark plugs and put a towel over the cylinders. If ther eis water in there it will shoot everywhere. Don't run the starter for long periods and let it cool down. That is the only way I know to get the water out unless you pull the rotary valve.
If there was much water in the engine it would just lock up. If he tried to start it with water in the engine he could have damaged the rotary valve. I"d pull the rotary valve and have a look. Glad you finally got some usable information from the pervious owner. They seldom tell the whole truth and most don't know any better anyway. Good Luck !!

I was checking my youtube videos and came across this one. This was my first time checking the fuel pressure. You can see the problem I was having with the fuel pressure regulator by the pressure drop. Some people posted that the pressure should not drop at ll when the pump shuts off. The engines don't seem to notice a few psi less, but right is right. My current pressure check holds very well at 50psi and the ski seems to be happy.

When I got it a tried to fire only some spit at this point came out. And as you see a tiny bit sprays out the throttle body. Maybe I should dig all the way do to see if Rotary valve is scratched or bent ...?

I am waiting on my new FP test gauge to arrive and check
