Spitting too much fuel??
 

After buying aftermarket bolt on parts my LS, I've been having problems starting the car. It seems like it is spitting out way too much fuel. Sometimes the car starts like its brand new and sometimes it don't start at all. When it don't start, I have to remove the spark plugs and wipe off all the fuel. I cannon figure out why it is doing this... could it be that the bolt on mods changed something to where I need to adjust air/fuel ratio?


BTW: I have intake/exhaust manifolds, cold air intake, fuel rail, and bigger exhaust piping.

could be your fuel rail....why did you change that in the first place? the stock one is fine for the bolt ons you mentioned....if your gonna boost then yea you'll change ur fuel rail, get colder plugs, higher injectors, and FPR......but for a intake/exhaust...put back your old rail and see what happens.....if you gotta wipe off your plugs with fuel, then your plugs aren't able to burn the fuel fast enough its gettin too much

A few weeks ago, I think we told you that the aftermarket was not needed at your level of modification. I'll be that the aftermarket fuel rail is the major determinant in why you are running so rich.

Re-install your stock fuel rail, reset your ECU and you should be fine.

How do you reset the ECU?

The stock fuel rail don't fit too well with the aftermarket intake manifold. The fuel rail came with the manifold. So you guys don't think that a FPR will solve this problem?

I found that post in less than 20 seconds.

How do I adjust air/fuel ratio?

Your gonna need a fuel managment system ~~~~HONDATA......but like i said before your mods are in the baby stage still, you aren't even close to being some wat moderate with mods........i don't understand why the stock rail doesn't fit, wat manifold did you get?.....if you want your car running fine again you gotta figure a way to get the stock rail back in....my 2 cents, good luck;)

Ill work on getting the stock rail to fit today and I'll post back, thanks for the inputs.

Okay bad news for me, I switched the fuel rail back to stock and reset the ECU, still have the same problem.

I'm not sure if this is related to this start up problem but my coolant level dies down really fast... where the heck is all the coolant going? I never see any drip of coolant anywhere.

do you see white smoke out of your exhaust? if so then your burning coolant that where its goin
