Car will not start...

[Livefast]

Switched from E85 back to RON98 fuel.
Car started fine couple days.
Last friday morning it didnt start (cold engine). Starter was running but car just not want to start up.
After estimate 10mins of trying it fired up. And worked fine whole day and saturday.No matter if engine was warm or not. Worked fine....
Saturday night it did it again. But started after couple mins.Drove it to friends yard.
Sunday i went to pick it up.And again,would not start. Tried so long that battery went out. Put it on charger.Went again yesterday and changed new spark plugs. Still had to try so long that battery went out.Today i changed main relay and switch all green relays between each other. Nothing..... Car is still standing there
Also tryed with different ROM´s. No changes.....
What i know is that car is getting fuel. Sparkplugs go wet,i smell gas when i try long,and there is also fumes coming out of exhaust.....

Today i ordered new blue relays from SSP,but it will take some time because i had to transfer money to my Paypal account.

Any idea?

Did you have this problem on E85, or when you were on gasoline before that?

What year is your Ralliart? What is the average temperature when you're trying to start it?

Mine had a hard time starting this past Friday when it reached freezing temps at 0530 in the morning, started after a couple of minutes and been fine since.

Something in your tune and super cold may be disagreeing.

Once you get the cylinders flooded with fuel, you need to dig back out of that hole. You can unplug the injector connectors or the fuel pump to crank it for a while to dry out the cylinders. It may get to a point where it starts to fire and you can reconnect them.

If the fuel relay (the secondary one we all replace with the blue one) fails, that only affects full throttle and it would lean out. That can not cause this problem.

Otherwise you need to confirm that you have fuel, spark and compression in the cylinder. If you have all that at the right time, the car starts and runs.

Nope.Problems started couple days after fuel swap.

Car is 2009

It´s not temp what it causing this right now. We had many freezing temps week ago. Now it´s quite warm again.

Not cold at moment. Was a lot colder week ago.
And i also try with different roms.

I will do and check all that. THANKS

Okay,i THINK it´s something on fuel delivery.

I did what Mike told. Unplugged injector connectors,and it fired up imediatly.
Continue starting that all possible fuel will burn out from cylinders.
Plugged connectors back,but didnt start. Again unplugged and started car.
Fired up and i connect very fast everything,before it shut off.
And finally it was running. I let it idle a while and giving some gas time to time.
After estimate 5min idle,it just started lowing revs and shut off
Again tried start it,but nothing. Only way was that i disconnected connectors,started,and put all back when car was running again.
But now it wasnt good idle at all. Had to give throttle little bit all time,or engine shut off.And i try many many times.
AFR was also quite low. Almost same that i normally have on under WOT.
When i put gear on,it shutted off imediatly. Needed a lot throttle to move.
And black smoke was coming out of exhaust when giving throttle gear on.
Manage to drive it out from that yard,so tow truck can come pick it up now.
Have to call tow car to pick it up for tomorrow or friday. Thank god i just got new own garage.

So what i think all of this:
Engine is getting too much fuel on start. And when engine running,it gets too little.I dont know....Hard to say.But what i know,it´s not tune.Tried with different roms.

Maybe just need to start with compression test.And if it shows ok,then have to start cleaning fuel lines.

What do you guys think?

Can you provide more info on the mods that you are currently running, plus any changes you've made recently?

Also, how did you "switch" from e85 to regular gas? Did you use up all e85 and then fill it with regular or...?

[razorlab]

Bad injectors maybe, I can't remember, are you running DW's?

Just a hunch..

No changes recently.
Engine mods:
-InjectorDynamics 1000cc
-Blaqops E85 kit + Walbro pump
-Fujita EvoX intake
-EvoX OEM turbo & manifold.
-3port boost solenoid
-Turbo XS downpipe & catted testpipe
-Synapse diverter valve
-Ultimate racing fmic,uicp&licp

I use up all that i can.But i didnt suck left of 85´s out of tank or anything
And remember it didnt do all of this just after swap.
I drove couple days and two tanks.So im sure there was 98% pure fuel then.
