    No injector pulse 1990 chevy silverado
    I have a 1990 chevy silverado that started by bogging down as if it were running out of gas, then finally just quit, after replacing the fuel pump with no results, I found I have no injector pulse when cranking. I can get it to run in my driveway if I pour a little gas down the tbi, but it will not start back up on its own after I shut it off. I ran a hot test light to the purple/white connector at the 4 wire connecter at the
    Module and the injectors did pulse and inject a shot of fuel, so I replaced the module in the distributer, but no luck. I also cleaned all the grounds I could find but again no luck. I am leaning toward replacing the ecm, but would like to make sure that is my problem before dropping the cash for it. Any ideas or suggestions would be greatly appreciated.
