What did you use to pull codes? If the SES light came on it set a code.

VC harness or connectors maybe?:shrug:

what kind of code reader did you use? some scanners wont read injector drive module codes. if a valve cover wire or injector is misfiring it will set a code in the idm not the pcm. can you have somone with a differant scanner test it. an injector buzz test will tell you if the vc or wires are to blam.

oops sorry forgot about you saying no display. id take the chip out to help eliminate the problem. still need a good scanner to read codes and look at the data stream to see whats going on.

Generic OBDII scanners won't read the codes on a PSD. Get a good scanner hooked up to it. As for the chip display I don't know, as was said, pull it completely out and see what happens.

Stop throwing parts at it and get a good code reader... You need to run a few tests, Injector buzz test, KOEO test... Your just wasting time and money throwing parts at it...
