    Sounds like the ignition module went out. That is what fires the injectors. common issue with the 88-94 chevys.
  3. Thanks i had already changed the ignition module i actually discovered the problem yesterday i didnt know that new ecm didnt come with proms so i got to get new proms i had already turned in my old ecm with the proms in for the core charge but thanks again

    Well you didnt mention that you had replaced the ECM, or the ignition module. Glad you got it going.
