Hey all,
I am just finishing up a turbo build and am having big issues. To begin with, the car will not stay running unless my fuel pump is off and my fuel pressure regulator is unplugged, otherwise if its plugged in and the pump is on, it will run for a couple seconds then flood out. I am getting air fuel and spark I know, but I'm still confused.

Can I get spark still and my ignitor be bad? Cause I figured that might be a possibility. I have a aem fuel pressure regulator in the works so we'll see if that helps. But any ideas otherwise? I've been searching and have only found a couple helpful hints. Thanks in advance guys....

are you running stock FPR now?

did you change our you injectors?

Yes, sorry I didn't mention my setup, I have a stock FPR right now, I am running 1000cc injectors with a walbro 255lph pump, built bottom end, etc. If you have any more questions that will help you help me let me know. Thanks
Max

 

Did you change your engine management to compensate for the 1000CC injectors.

What management are you using?

I guess I'm leaving everything out, lol. But yes, I'm running hondata s300 with a good map just for break in, no boosting, rev limit at 4000rpms. And this is an h22 in a 4th gen lude....

Do you have a wideband that you can log and post up.
Also can you post your fuel table from the S300? Something can’t be calibrated right.

It really sounds like your flooding the motor out.

If your igniter is problematic, it could still spark, but if its dead I don’t think you would get any spark.

I do have a wideband, since I can't rev above 1500-2000 rpms, my a/f's from the wideband are right around 13.5-14, then it reads lean at 2000 and feels like a cutoff, and I haven't gone any further cause I don't want any detonation....
Here are the high and low fuel maps, sorry for the size but I couldn't read anything when I shrunk it... let me know!

Anyone have any ideas? If I had the IACV unplugged would that cause this problem? Just a thought...
Max

 

IF the engine is flooding with fuel, most likely one of your injector is bad. Put back the oem and see if it idles.

 

I don't have the stock injectors anymore, would it be worth it to have them cleaned?
Max

 

arent those the hi cam fuel maps? i think you should be concentrate on the low cam fuel maps in this case!

unplug all injector clips and put them on again and make sure they are in snug...and yea double check the orde rof the spark wires too and snug too! IACV doesnt give fuel cut as i know

have a resistor box hooked to those 1000's?

Yes, resistor box is hooked up. I was messing around with the car again today and I heard when I turned the car off a slight buzzing/humming sound coming from the small module on the front side of the intake manifold where the injectors plug into. Looks like a relay or something... What is that and what does it do?
Max

 

All I saw there was two different high cam fuel maps.

Whoops, fixed...

 

Just an update, I believe I have found my problem, I think that I flooded my motor, which would explain why the car only runs when the fuel pump is off and can only rev up to 3k before it leans out. Since the motor has a built bottom end, when everything was put back together and I was troubleshooting it since it wouldn't start, the fuel pump primed many times just dumping fuel into the chambers, and now that it runs, I have straight unburned fuel coming out my exhaust. So what I'm going to do is pull all my plugs, drop a small amount of oil into each cylinder to seat the rings, let the fuel clear/dry out, and try this all over again. let me know what ya'll think and if you have any more suggestions!
Max

 

Well, an update on the car, I flushed all the gas out and placed some oil in each cylinder, the car will now run with the fuel pump on, which is progress. However, I still cannot rev past 2k and there was some faint white smoke coming from my breather valve on the valve cover, leading me to possibly believe that my headgasket is blown, but hopefully not, cause this is a fresh rebuild, however I may have personally screwed up putting on the head, but I thought I torqued them down correctly and everything.

However, another question I had was should I use a catch can setup instead of my pcv valve so I don't pressurize the crankcase? Cause that was something that I thought might have caused the smoke. And one last remark, I filled the car up with coolant and went to bleed the system while the car was running but it was bone dry after running for 5minutes, no coolant whatsoever. Anyways, any help would be greatly appreciated! Thanks
Max

 

Bump for help

 

check these:
1-compression
2-leakdown
3-injector offset
4-oil pressure

i recommend you to use stock injectors or any high impedance injectors to see if thats gonna do the fix...cause i have a feeling your 1000s probably need some offset settings or drivers! if the injector have a delay its possible to smoke slightly from the crank breather!

If u had coolant and now u dont, and u SAY there is gas coming from the exhaust, it was probably coolant.Ur headgasket is probably upside down or soemthing.

check the gasket from the vtec soleniod side! (i mean where the gasket is sticking out of the head on the side) if you see a part number written "P30....etc" on the top then the gasket is put right, but if its flipped then its upside down!

 

Okay, well I couldn't see the gasket sticking out of the side at all, however I may have had poor light. But if the gasket was upside down, I assume that the wells wouldn't be aligned for coolant or anything properly, would that cause my problems??? Also I don't know if this is normal, but my turbo and exhaust manifold are unbelievable hot even after running at 2krpms or below for like 5 minutes....

One last thing, I took the thermostat out of the housing to let coolant in and also disconnected my top charge pipe and the car ran and idled and even revved fine (i only tried to 3krpms) but once I re-connected that charge pipe and drove it around in first gear at no more than 2k rpms it fell flat on its face and wouldn't rev, once again pegged rich on my wideband o2. Anyways, problems are slowly lessening and I appreciate everyones help thus far, and hopefully ya'll can help me figure it all out! Thanks again

what map sensor are you using...???

i had a problem with my GM 3 bar... i had it started, and running, drove it a bit. then all of a sudden it flooded... so i changed plugs... same thing...

Took me a few hours on the side of the road to figure out what was causing it... i tried stock injectors back in it, and same problem... i could even unplug the injectors and start it, and it would run for 8 seconds without them plugged in.... WAY to much fuel..

i burnt a chip (luckly i had my burner in the car) and used the old map sensor, and she fired right up....

 

When you burnt your chip were you running hondata or crome or uberdata? I didn't think you could burn a hondata chip... Anyways, I suppose I'll look into the map sensor failing, I just hope it isn't cause its more money to spend, would you recommend any particular brand???
