Down gas! Sorry, bad joke.

Well, I guess I found my no start issue. I started Anita with starter fluid and she jumped to life! I have new injectors that are unproven, so that might be the issue as well. However, the gas is over 2 years old so I bet that's my problem. Any remedies other than drain the tank?

 

2 years old? Not driving much these days? I'd drain it regardless. You might want to drain it from the pick up at the bottom of the tank so that you can replace the screen filter at the same time. I'd think you are more likely to get the crud out that way vs. trying to pump it out. Fairly easy job -- put the rears on ramps, undo the strap over the tank cover, remove the hose at the bottom of the tank (be ready with a big bucket or three) and then remove the drain-tube/screen with an open end wrench.

 

Too late to add fuel stabilizer, but the gas should not cause a no-start even if left that long, so I think you have other issues.

Drain and refil if you must, but I would just add some fresh gas to it and run the first tank to as low as you can before refilling with a full tank of the fresh stuff. You might get some performance issues until you burn all the old gas, so I wouldn't try to tune anything until your second tank of fresh gas.

I guess I should check my new injectors first, but I can't believe all 4 of them are bad. My noid tester says I am getting fire to all of the injectors, so it's either all 4 injectors are bad, or the gas has deteriorated to the point the car won't start. Waddaya think?

 

Are you getting gas into the cylinders? If you pull a plug you should be able to tell from the smell and see it with a flashlight. Are they stock injectors? If you put 9v battery leads to the injectors, you should hear them click if they are good. Pretty darn unlikely they all failed at once... Have you checked fuel pressure?

 

It seems unlikely that all your injectors are bad, did you do any other work in the interim that might cause a no-start? Also, how much gas is in the tank?

This is what I would do if I have room to add some fresh fuel to the tank. if you have 1/2 tank, top it up with fresh and feed some of the new mixture (50% old/ 50% new) through the fuel lines to the fuel rail. Disconnect the fuel line from the fuel rail & using a catch can run the pump. Reconnect the fuel line and if you still have a no-start, look for other causes.

 

if your charge on your battery is not up enough- it will not fire up.

 

The injectors were bought used from a friend of evil944t who used them to dyno an engine (or was it a little old lady who used them to drive to church - I can't remember). They have maybe 200 miles on them (hours would be better terminology). I know I have gas to the rail and the noid says there is power to the injectors. I do NOT know if the injectors are firing. I guess I should put the old injectors in to work from an established baseline.

The tank is nearly 3/4 full. I have a charger on the battery and it has charged about 24 hours. I need to check to see if the charging is finished.

Thanx for the help thus far!

 

Michelle,

I had an unfortunate instance before a DE session where I pumped my tank full with gas that had water. Its a long story but I managed to run to the auto parts store and buy a siphon ($12) which went to the bottom of the tank. The remaining fuel which was in the system was removed by removing the nipple from the fuel rail and having the pump drain it.

BTW....did you remove the nipple and smell the gas? I was able to get a cup in a clear glass bottle to see the seperation of the water and fuel after it settled. You can see all the fuel we removed outside the paddock.

I'm going out to swap the injectors now. I'll take a whiff and sample of gas when I purge the rail.

 

Well, it was the injectors. I switched back to the stock injectors and she fired right up! Anybody have a set of 72# injectors they wanna sell?

 

Its probably easier to send them out to have them bench flowed and cleaned.

 

Are you adding larger injectors to you car without changing the chips?

 

I have a MaxTune and new t04e turbo

 

I may just do this.
