Car would choke out so changed fuel filter, ran good for a month and would do it again, changed fuel filter again, same thing, lasted for about a month, next changed fuel pump. It is happening again. Could it be the fuel injectors? Or the computer? Can all the fuel injectors go bad at the same time?

Hi btjfarnham, Welcome to 2carpros and TY for the donation

Check for power on the pink and black wire on the injector harness if you have it -get a noid lite and hook it up to the injector harness if the noid lite doesn't flash -the computer ground driver for the injector is defective

Can all 6 fuel injectors go bad at the same time? What would cause this? Thanks.

I see its a 6 cylinder-wasn't listed I was shooting in the dark with this. Okay the pink and black wire powers all the injectors if its shorted to ground it will drag the rest of them down they share the same circuit
