hi guys,

i was wondering if there was a way to test the injectors outside of the car? the reason why i ask this is because i am going to the local pick and pull to grab some and want to know if i could somehow test them with a multi meter outside of the car. also i need the tcs relays and am wondering if i could test those somehow also. if you guys could respond fast as i am going there in a little bit thanks

Just put the meter leads on the two electrical connectors of the injector to get a reading.

The TCS relay is part number 25230-89981.

Your local NAPA has them for $18. I suppose you could put some juice to them and see if they click. If you have the slip/TCS lights on in the dash then your relays are bad. These are the two blue ones underneath of the battery tray.

Make sure to hit up the wanted ads in the classifieds for used injectors if you test any that are bad. NICO really came through for me when replacing mine recently.

Good luck!
