I got 125 miles on the car today so I deceided to try 5th gear full throttle pull and before the tb open anymore than just moderate pedaling the car falls on it's face and does nothing.
I just got back so it's time to diagnose.

I'm leaning towards tps or fuel pump.

With moderate throttle the car is starting to run hard.
So hard infact that leaving a conner pretty normal it started to chirp up the tires.

Anyone have idea's ?

Going to try another TB now.

 

Well tps is ruled out.
I've tryied 2 others.

My fuel pressure gauge stays steady @ 56psi at the fuel block so it's getting pressure to the fuel rails.
Not enough volume from the oem pump ?

Is there anything that would cut the injectors ?
or is it possible they are getting maxxed out ?

 

Fuel reg return line is showing the same pressure as the gauge of the fuel going in.

One thing I find weird is the gauge retains no pressure when you turn the key off.
instint pressure drop.

I guess I'm going to let the return run into a bottle to check the volume next.

 

Did a couple more tests.

No fuel leaaking out of the vac side on the reg so diaphraghm is good.

Volume test failed in my eyes.
I got about 2oz of fuel out the regulators return in 30 seconds.
It should produce 15 times the volume.

So ordering the 255 walbro.
Perhaps I should check the fuel filter aswell.

 

The fuel pressure gauge does not hold pressure when you turn the car off.

Are you still on the CL-P ecu and injectors?

 

No,fuel pressure instintly drops.

yea still have clp ecu and injectors in there.
I'm almost sure the injectors are the same between the type s and clp.
Ordered a fuel pump and another regulator.

 

Any CEL? Bower just drops? does it feel as though the ecu is limiting it or something else?

 

do you have a CAT ?

 

I was confirming that, its the same in my car.

 

It feels like lack of fuel.
Like a total cut when the tb gets open to far.
Wether it's from the ecu or fuel related componets I can not be totally sure till replacements are here.
I just came in from taking the pump out.
Now just a waiting game.
I have no cel and no codes on the scanner either.
I have had a icav vavle code before but nothing recently.
figured that was from restricting it.

The car pulls hard part throttle just when I try to open the tb power goes flat and sounds like detonation so I won't go there but for a second.
Possiblity I've advanced the crank sensor too far too.

I wish someone could give me a live parameter readings of there car so I could compare some things

 

do you have a CAT

 

Map sensor or fuel pump. Do you have a wideband ? Whats the ratio when you hit wot?

 

I changed 2 differnt maps and they read the same.
Fuel pump definitly does not have enough volume.
But, The car is acting like their is to much advance.
wether it's from the the fuel situation or actual placement of the sensor I don't know.
I don't think I moved it even a 1/8"
more closer to 1/16".
Bet your ass before the fuel stuff comes I will be returning the sensor back to it's oem position.

I got a xlr8 cat with a 02 extension,everything else is wide open.
The rear o2 was reading a steady 1.275 if I remember correctly.
front o2 was reading .4-.8

 

Moved crank shaft sensor back.
It was moved a little bit more than I thought.
I'm willing to bet that was the biggest problem.
Just got to put lower timming cover,pulley and belts back on.
Save the easy stuff for tomorrow.

No one can say I don't put in wrench time that's for sure.
I think the wife is starting to hate me

 

i am still waiting for a bumper sticker that says.. "I love wrenching"

 

This is most likely your issue. It should only have one position. Moving it in hopes of advancing timing will only have the ecu put in more than it should when needed.

 

Does anyone know how this issue was fixed, im having the same problem, and i have changed the plugs(iridium ngk), adjusted the valves, cleaned the manifold, cleaned egr ports and valve. I cant figure it out??
