So i just swapped out my flexplate the other day and when I put everything back together my car wont start!

It was starting fine before I swapped the plate. I have spark and I'm getting fuel to the rails. I started testing voltages on the injector plugs and couldnt get a reading on any of them. I then went back and checked voltage at the injector fuses and could not get a reading on either of them.

What could have happened while changing the flexplate to cause this problem?

Is there any small thing that is able to stop power from reaching the injector fuses? I tested the pick up coil and that tests fine

Also my car does not have VATS

 

hmmm.. well after a full day of playing around with all components involved in the injector circuit and lots of testing the problem is gone.

Not sure what I changed exactly, must have been a loose connection somewhere.

 

i'm putting a 92 camaro tpi on my 82 vette.i used a custom made harness.and comp.with the vat taken out.it don't want to run.it idles rough by dieseling' if you start to drive itseems ok but when you get down on it it just nosedives' ichecked the power going to the injectors'. when i checked the power to the inj.both sides were hot' i no each side of the inj has a+ an a- please what's my problem?
