Isnt there some thing with 1.6 cars where the FP is wired up through the stock air meter? I think you have to jumper something or something.

(I've got an NB so my NA6 knowledge is somewhat suspect)

 

You are massively correct E02K.

Jumped the wire from fuel pump to the AFM and the car instantly started after I accidentally turned the key to far! Holy **** that surprised me.

I shut it down quickly though since it was completely unintentional.

After I jumped to AFM there is a very loud buzzing noise coming from beneath the cars gauges... not sure why this is.

I ran a wire from the fuel pump and connected it to these two points on the AFM

 

Looks like it is the fuel pump relay under the dash that is buzzing loudly.

Scared I may have an air leak at the turbo. High pitched whistle on shut down.

Oil gauge isn't responding to pressure so I may need to clean the oil sender pin and find out if that is the problem.

 

SO IT LIVES?

 

 

Just...not a very healthy alive!

 

Can you confirm it actually has pressure? Last thing you need is to damage this work of art.

 

I'm going to pull the turbo oil feed and see for sure that oil is flowing.

 

So... accidental first start?

 

Yeah it seriously didn't even crank for 1/2 a second and it suddenly started up. No stumbling or anything. It does have a loping idle though. Can't tell too much without the tach working.

 

Pulled the CAS and COP and cranked with the oil feed line from the turbo off. It dumped about 1/2 cup of oil into the cup, so I don't think any damage is happening to the turbo and it is developing oil pressure.

Also switched the tach settings in tuner studio to ON, but there was interference from the PWM signal so I changed it to tach and still no response from the gauges.

If my tach out is on 2B on MS, which is the correct output for tunerstudio?

I also need to set the 99 tps/IAT to a new setting. Tunerstudio is reading it at 51% throttle at idle, but it is idling at 2350 rpm.*edit* I may have the 5v and ground reversed after a little reading.

When I have the fuel pump jumped it is reading the fuel pump at 100% duty cycle as well, which may be why I'm getting such a loud noise from the fuel pump relay.

 

The fuel pump is either on or off, no MX5 made (yet) uses PWM on the fuel pump.

More likely you just have a bad relay.

 

I'd agree but that would mean both relays from both cars I tried were bad, odd considering both worked perfectly prior to this build.

I think I may have ran the wire from the fuel pump to the AFM incorrectly to jump it. We'll see.

 

Wiring is such a pain in the ***. I don't even like putting in aftermarket stereos anymore.

 

Yep just what I figured. See post 2054

 

Be careful with that. Wouldnt want oil squirting all over your clean car. I would tape the feed into a water bottle.

 

 

You'd be opposed to some real skeet skeet?

Don't worry, I wouldn't just let the oil pour out over the engine bay!

The good news is that oil is flowing, how much pressure it is developing is still the question.

 

I needed a break from tunerstudio and researching stuff so I decided to get my headlights and other lights working right.

Forgot to check the continuity of the wires when I installed the new harness and it turns out grounding to the starter is not so good idea.

The diode I had put in was in the wrong direction so it wasn't blocking the high beams when only the low beams were on. So after changing the direction and getting everything sorted out they work perfectly.

My god they are bright too. When all 4 lights are on it makes the factory xenons on my Jetta look weak and dim.





Also thought I'd take a quick shot of the gauges with the white LEDs I put in. The bleeding around the needle caps is only due to them not being pressed on firmly since I need to align them once my tach starts working. The brightness of the trip meter and total miles is over-accentuated by the camera. It looks great IRL.

 

Classy as $!&#. Well done sir.
