sad and upset

[bentvalves]

That I have spent so much time and energy under the hood of this car and it is not running ! Its taking a big dump on my face after installing a new turbocharger, it is driving me bonkers, not turbo related, coincidental that Im having problems now but it makes it so hard to accept that something else is wrong.

[skunkmonkey]

that engine bay is looking awesome! sorry to hear about the engine troubles though...

[Buddyworm]

!@#$ing awesome. That's a beautiful engine bay, especially the red bull can.

[meminto]

Yeah man, very tidy engine bay..

I understand your pain, totally understand...

[NUT-CSE]

I know the feeling, my car has been siting in the garage for 2 years now and its gonna be awhile before its roadworthy.

[zmannz]

I feel your pain ks. I started my project last year with hopes of it being drivable about now, but I don't even have my motor in yet. I got ripped off on my welder and tools, kinda put me back. Nice bay though man, I am eager to get mine that far.

[ca18detgabby]

holy crap greg that is hot.

shall we play the game...... what isnt it doing?

what do you mean it took a dump on your face ? HG? rod through the block? something else?

could it be something as stupid as old fuel that isnt good anymore or clogged fuel lines.

what happened

sorry to hear your issues greg

[bentvalves]

It was going great with the s15 turbo, I had to futz with it, installed 2871, now it struggles to start and is being generally defiant.

I'll keep you guys updated when it stops playing hard to get.

haha i just read what you wrote again gabby and noticed that smiley face licking his lips at the mention of "dump on face" lol haha one day I will smile whole-heartedly again!

Just run it off a map sensor, IAT sensor, remote mounted coils, and a crank position sensor. Its so bulletproof.

Slap that bish around, don't let it tell you what it wants to do. My car ran horribly when I started it up from sitting for a month, so I limped it out onto the street and did a full 7500rpm 2nd gear pull and now it runs perfectly.

[bentvalves]

yea one day Id like to upgrage to a D-jetro SR pfc to be able to ditch the MAF and have IAT compensation tables n shyet.

[MeanGreenS13]

karma is a ***** greg. when i didnt want her anymore, i sent her to you for sloppy seconds. MUAH!

seriously tho... hope you get it fixed soon, ill be knockin on your door before you know it.

[r34 gtr]

Its a long drive and one crazy-a** traffic circle to knock on his door, just warning you.

[bentvalves]

dude if you come a' knockin and my tail is still between my legs..............

I dont even feel like joking, I just want to be negative, excuse me.

it has compression, correct MAF voltage, correct TPS voltage, correct WTS voltage, no restriction in intake, no restriction in exhaust, no boost/vac leak, no nuthin.

oh god what did I ever do to deserve this craziness? I feel like someone has sabotaged my car. Bad input = bad output....but all the inputs are there.

It fires but just DOES NOT want to run.

We're gonna need more info on your car's specs and specific symptoms regarding the engine issues. What's your ECU? Maf? Timing? Cams? Injectors?

-m

[Dattebayo]

...interesting!

It looks like an as$-backwards V-mount setup.

[karism]

Holy Poop! Look at that engine bay!!!!!

Keep your head up!You will figure it out soon enough.

Cant help with suggestions just yet,will have to think

[r34 gtr]

Did you try setting your timing to not off the chart ridiculous? I saw that thing run, I know it runs, just tell it to straighten up or die!

EDIT: Its totally timing. 100%. Will stake my life on it.

[bentvalves]

yea but the cam timing was not touched, timing in the maps is fine, I tried adding/subtracting 10 degrees and nada man, no difference.

I have a feeling its something electrical related. The fuse block under my hood, what do the 5 relays there control?

3 green, 1 grey, 1 blue. The cover/panel is faded, and I cant find anything online....yet.

[r34 gtr]

Can't be anything important. Fuel pump, headlight relays, etc. I mean, I'm running a totally custom ECM and I still have all those relays untouched.

[ca18detgabby]

how is battery voltage?

assuming you pulled the manifold off did you relock down your piping right?

think maybe something spliced is grounding out? (what is the red wire that looks to be unhooked on the intake side)

It sounds like a maf issue. what hapens when you turn it on..... you tell is it doesnt run.... what does it do? codes? try unplugging the maf and see if conditions change.

Ps eye spy? I totally didnt even think about it till i saw the break booster.... even though you told me you have a greddy manifold.

[bentvalves]

everything you've suggested has been looked into, and everything checks out

I promise I'll keep this updated and let you guys know exactly what the problem is, no matter how embarrising it may be!

[mazikowski]

Sorry to hear you're having trouble... but I must say that engine bay is VERY NICE! love the redbull can you have in there

[r34 gtr]

Yeah, its probably something like a vacuum line is loose, or a vacuum cap came off the underside of the TB or something dumb that will take you a week to find. You have a compressor (Ive seen it), so pressurize the intake tract and make sure it holds air. Then try it with the TB open to see if youve got any kind of leak in the intake manifold gaskets.

A few posts up said he has compression.

maybe a crack in the break booster line..... those are horrible to find.

you would think with a vac issue or a/f issue he would have gauges reading what is going on and tell him that it is a problem.

Did you accidently flood your engine?

is fuel making it to your fuel rail? how is the fuel pressure?

come on now greg.... cheer up a bit.... share with us what you have tired and lets see what we can help you weed out.

[r34 gtr]

Towlie would get high and come up with a great idea that would later get him in bigger trouble than he was already in. Just a thought/suggestion.

I have a custom piece of intercooler piping with a schrader valve on it that I use to pressure test the intake system. You can weld, give it a try. My car was running rough and I pressure tested the intake manifold and found a leak at the back, where the manifolds meet. Who knows man, when I have a problem like that I just check everything now a days.

[bentvalves]

nah man, sadly I can inform you that is not the issue, that compressor gets used often.

but umm, im just gonna go cry for the rest of the week and come back to her some other time.

yes folks, I am walking away for the time being.

a buddy told me he would give me a hand, we'll see what comes of that promise.

down in a hole

Greg

p.s. thats coo, schrader valve in the intercooler piping was my brain child damnit!

no but seriously, been meaning to do that for some time now.

[r34 gtr]

Can you describe what its doing in detail? Then I can stew over it for a week and tell you what is probably wrong with the thing.

[bentvalves]

I should get a vid up when I care again, but again.

It fires over, has fuel pressure, is getting spark, but just wont run. You give it throttle input and it says "maaan, I dont thiiink so" Will not idle good enough to pull more than 10" of vaccuum.

I wish these fuel injectors werent sucha pain to remove, I think thats the next logical step.....view them spraying and make sure none are stuck?

AFR's are rich, Power FC scaled for injectors and AFM however, should (as it has in the past) fire right up and idle beutifully with no AICV and cold start jazz.

and the list of what has been gone through is bonkers, everything you could think of. I have wideband O2, in car fuel pressure, boost/vac, and ECU operating parameters at my fingertips, to check TPS voltage, I go into sensor check under the ETC menue and view it. It makes diagnosing a lot easier, when theres a demon that isnt hiding.

[r34 gtr]

Man that sounds like you forgot to tighten down the upper manifold to the lower manifold or something. Did you work on it hammered-a** drunk and f*ck around with the intake side at all? I mean, I don't know about you, but I usually get pretty drunk while doing external engine work on my car.

[bentvalves]

LOL hahaha "I mean, I dont know about you.........."
