Kent-Moore J-44603 Noid Light (Bosch 2) (J44603)

Do an EBay search for noid light set. You can get a 6-8 piece set for less than $20. They'll have different sizes to fit the various Bosch and Denso injectors.

Finally scored noid lights and it appears that all is well on the computer end. This means that wrenches must come out and I must smell like fuel.

Squirters checked out fine, now I'm drinking on it. Any thoughts or inspiration?

....and now the fuel pump won't turn on.

Edit:
Unless I manually turn it on in the test window. Weird.

So, wiring good, injectors good. Pump starting to die?

Some setting in the ECU off?

The pump turns on when activated in test-mode. Does someone want to dig through my MSQ that I'll post in a few days when I get my replacement SSD? Yes, two dead HDDs in one year.

You have fuel, you have spark, it should run if the engine is ok. Compression test?

The fuel pump will not turn on with the key, again. I can manually switch on the fuel pump in the output test window. That's unrelated to a lack of compression.

I'll test compression on Thursday or Friday, when I get my new SSD for the dead notebook...again.

I'd say that points to wiring or the settings. If it's intermittent, I'd lean towards a wiring or even the switch.

I'll check compression when I get the personal computer working again.

Witch switch? How could it be a wire issue if I can still activate the pump manually?

The fuel pump won't turn on if your TPS is more than the "flood clear" settings.

Datalog?

**** yes, I love you and want to be with you, too bad you're married and probably into dudes.

I remember that TPS is still whacked-out and reads either 1000%+ or 0%. I never got the TPS to work and just used EAE. ****, I've been chasing my tail. Even when I ran the wire outside the car, through the window, it still read whacked-out values. I changed the TPS right before this happened.

I feel more relieved than embarrassed. I'm not sure how to fix the TPS problem, it's been rewired and replaced on more than one occasion.

Is there anything I can do to totally disable the TPS and rely solely on EAE?

EAE also requires normal AE to work properly.

I'm about to burn the car.

How can I isolate the problem to the TPS, wiring, or computer? Ouzo? The TPS was not whacked-out on the old MS2 computer.

Unplug TPS and switch to MAPdot not a workable (temporary) solution?

I still can't get my TPS to work properly. Well, it works, but until I raise the threshold above some crazy value, it trips out.

MAPdot FTW.

Get me a few photos of your TPS setup.
