Bought Precision injectors off a guy from ebay used AND now im wondering if they still work before i put them in and blow my newly boosted motor!
Is there a way to see if all are working properly?
also, he said they are 550cc but im kinda sure that precision makes 525 and something higher then 550. HOW DO I CHECK THE CC SIZS AND IF THEY ARE LOW/HIGH IMPEDANCE?
THANKS GUYS

 

You can take them to a fuel injector place and have them test the injectors. Or you can hook them up to your rail and harness and try and start the car and see if the spray.

 

wouldnt that be bad for the motor??!!
trying to get it to start and no gas in a boosted car???

 

No. You do the same thing when you do a compression test by disconnecting the ecu/fuse to disable the injectors.

It's only harmful if the engine is already running at heavy load.

 

It just wouldnt start, not going to hurt anything

 

well im worried about 3 of the 4 working and im like OH the car started and is running
never did a comp. test. are you saying have the injectors in and pull the ecu fuse and then try to start the car?
