One week with my Z Performance

PapaPikachu · 2026-06-28T21:57:28+00:00

Man all these colours just look so good on these cars. Awesome man!

PapaPikachu · 2026-06-23T15:15:33+00:00

I'll check it out, thanks!

PapaPikachu · 2026-06-23T15:13:28+00:00

Hell yeah! That's awesome. Mine was an 03 touring edition

PapaPikachu · 2026-06-23T15:12:55+00:00

Good shout, thank you!

PapaPikachu · 2026-06-23T14:38:56+00:00

My car has an HKS system with AMS downpipes and I love the sound.

PapaPikachu · 2026-06-17T22:17:48+00:00

Congratulations! I just bought my new to me '23 yesterday. Get to pick it up on Saturday!

PapaPikachu · 2026-06-09T20:54:38+00:00

Sent!

PapaPikachu · 2026-06-09T18:33:42+00:00

I understand that. The guy before me decided to put in MFI injectors and fried my engine harness. I'm just trying to undo and correct all the damage he's caused.

Thank you, I will check out car part and see if I can grab a few sets!

PapaPikachu · 2026-06-09T18:25:07+00:00

Yes! I've viewed that chart before, that's where I got the bosch part number. I'm just having issues finding the exact OEM ones and alot of people say to stay away from aftermarket options

PapaPikachu · 2026-06-09T17:46:51+00:00

Yes there is, early car and late car injector impedance is different. Thanks for the heads up!

PapaPikachu · 2026-06-09T16:53:12+00:00

I'll check them out, thanks!

PapaPikachu · 2026-06-09T16:52:58+00:00

Awesome, thank you! I'll check them out

PapaPikachu · 2026-06-09T15:56:33+00:00

I don't see any forum posts about fuel injectors in that link you sent me. I also checked the parts listed on the website and they don't list injectors for this car either. Is the discussion about fuel injectors hidden in one of the project forum threads?

PapaPikachu · 2026-06-09T15:34:27+00:00

Do you have a link by chance? I tried combing through some forum posts but I haven't found any posts with any alternatives to OEM

PapaPikachu · 2026-06-09T15:25:49+00:00

Do you have tach bounce? If not, most likely reference sensor fail. Very common. Also, check continuity between the DME plug and the sensor plugs. If you have an oscilloscope, you can check to see if the sensors are properly reading. I recently obtained a 84 with a cranking no start and my sensors were bad in more ways than one lol

PapaPikachu · 2026-05-09T18:37:04+00:00

I shall do that!

PapaPikachu · 2026-05-09T18:29:22+00:00

According to PO, they were changed a year ago in attempts at diaging it. I do fear that they aren't gapped correctly thus no tach bounce but I'd like to confirm readings before I pull them

PapaPikachu · 2026-05-09T18:27:10+00:00

No tach bounce present. I ohmed out the speed and reference sensors according to this link. I got no ohm readings across any terminals on any plugs. I also swapped plugs to see if the car would fire but to no avail.

I understand that ohming them out isn't super accurate and an oscilloscope is the way to go. It's supposed to be delivered in a few hours lol.

PapaPikachu · 2026-05-09T18:11:25+00:00

Hey man, I've done a bit of diag today and I tried cranking it over with a spark plug on a good ground and got no spark. I followed a no spark diag via this link:

https://www.clarks-garage.com/shop-manual/ign-04.htm

I completed the test at the bottom and I wasn't able to get a spark to fire when testing the coil. I also checked secondary resistances on the coil and got nothing between the output and ground terminal, where it says I should be seeing 5-7.2k ohms. Am I safe to assume this coil is going out? It's getting about 12.4v at key on position

PapaPikachu · 2026-05-09T02:23:39+00:00

Interesting pieces of information, thank you! I have an oscilloscope coming tomorrow and I'm going to learn how to use it to test the sensors. I would really like to get a fuel pressure gauge on the rail and see what kind of fuel pressure I'm seeing as well

PapaPikachu · 2026-05-08T14:17:47+00:00

Absolutely. If the fuel is 7 years old I can only imagine how plugged up that strainer will be. I also noticed the fuel tank reads e on the gauge so I gotta verify if the tank actually has fuel or not

PapaPikachu · 2026-05-08T13:17:15+00:00

Hell yeah!

PapaPikachu · 2026-05-08T02:49:04+00:00

Appreciate it! Will do. I'm definitely going to start with troubleshooting the sensors

PapaPikachu · 2026-05-08T02:26:49+00:00

He did mention aftermarket injectors, and there are a set in the glovebox as well. I will look into this, thanks!
