Hey Steveo how exactly did you determine you had "a failure of the ecu sending the injector a fuel pulse signal"? Did the controller indicate a fault? I have the same FiTech setup and my truck recently started running a bit rough. I had initially suspected my cheap chinese MSD HEI or a intake manifold leak but after reading your post it got me thinking about my EFI. Thank you.
