I modded my wiring harness by pulling the factory gauge sensors and afm wiring.
Now the car will start and run for a few seconds then die. I know the injectors arnt firing but they are getting voltage.
Mysteriously my tach and CEL dont work anymore either. I've found a couple other threads with people having this problem but unfortunately no solution was ever posted.
If you guys can suggest anything to check i will be working on the car most of the day today.


Oh and i'm running maft pro speed density.

So stupid me, i forgot to plug in the plug under the dash. That fixed the cel and tach.
Still had code 14. Swapped out the is300 coils for stockers and the 14 went away. Then i started messing wit the cps timing. Now the only code im getting is 11 and it doesnt even fire anymore...

If you're gonna give advice please read the whole thread.
Tach and cel have been fixed.

Just swapped back to is300 coils and code 11 turned into codes 14, 24, 32, and 51.

Had a couple wires wrong on the coil pack harness, code 14 went away. 24, 32, and 51 remain.
Car still doesnt start. Doesnt really even try catching anymore.
I had the timing gun hooked up, while cranking the car the light wasnt coming on, but when i let off the key if the engine sputters a couple times the light flashes.
How would i get no spark when cranking but have spark after?

If you've got no spark while the engine is cranking then it sounds like a current problem. While the starter is cranking, there's not enough juice to power up the ECU, ignition and/or injectors. Check ground to the igniter, ECU and your MAFT-Pro
