RIPPR

I CHECKED FOR AIR RESTRICTION. EVERY THING SEEMS OK. TURBO CHARGER IS OK. JAKE BRAKE SOLINOIDS OK. FUEL INJECTORS OK. IN AN EARLIER RESPONSE FJH EXPLAINED HOW THE ECONOVANCE WORKS WHEN THE OIL PRES COMES UP THE ENGINE CLEARS UP AND RUNS GOOD. IT SEEMS LIKE EVEN AS THE OIL PRESSURE COMES UP THE ENGINE NEVER CLEARS UP. WELL THATS WHERE I AM NOW. THANKS, RIPP

thanks for the input i will look for air restriction or turbo problems

I POSTED A QUESTION YESTERDAY REGARDING E7 FUEL PUMP PART #'S BUT THE MORE I THINK ABOUT IT THE FUEL PUMP MAY NOT BE BAD. HERE IS WHAT HAPPENED I WAS DRIVING A ABOUT 65 MPH WHEN I NOTICED BLACK SMOKE FROM MY EXHAUST WHICH I NEVER HAVE AT 65 I PULLED OVER TO CHECK THE TRUCK AND WHEN I STOPPED THE ENGINE SOUNDED LIKE THE JAKE BRAKE WAS ON THEN I NOTICED IT WAS RUNNING ROUGH AND SPUTTERING BILLOWING BLACK SMOKE I MADE SURE THE ENGINE BRAKE WAS NOT ON I EVEN UNPLUGED THEM I MANAGED TO GET THE TRUCK HOME AND PARKED FOR THE NIGHT. IN THE MORNING I WENT OUT TO CHECK THE TRUCK TO SEE IF IT WOULD EVEN START NOT ONLY DID IT START BUT IT RAN GREAT NORMAL NO PROBLEMS. I CHECKED IT OUT EVERYTHING SEEMED FINE. I USED THE TRUCK FOR A COUPLE OF DAYS NO PROBLEM. THIRD MORNING I WENT TO START THE TRUCK IT STARTED BUT WAS BACK TO RUNNING BAD BLACK SMOKE ,SPUTTERING, CHUGGING , RUNNING ROUGH. WELL THATS WHERE I AM RIGHT NOW THE LOCAL MACK DEALER HERE IN SOUTH FLORIDA THINKS THE FUEL PUMP IS BAD I THINK IT MAY BE AN ECONOVANCE PROBLEM WHAT DO YOU GUYS THINK ANY IDEAS
