Posted this on oilburners, and thought someone here might have a clue. Quote: Originally Posted by fsmyth View Post Me, too. New injector pump, cranks great cold.

One oddity - I hooked the pump relays back up to the ECM (the wire that used to run the pump on the block, and now that hookup no longer runs the pump after 1st crank (the 3-second thing), but does keep the pumps running for about 10 seconds after the key is turned back OFF. WTF? <als> Replaced starter. Now turns over like it should. Now it will not crank at'all. Got a scan tool. First scan: 1388 (auto shutoff relay), 1689 (manuf. specific powertrain...) Cleared codes. Second scan: 1694 (no engine bus...), 1693 (communication w/ECM) Previous to this, O'Reilly scanned it, found 0463 (fuel level sensor), 0336 (crank sensor), and 1693 (comms w/ECM). These codes did not come back after clearing. Fuel pumps still acting stupid ( 1/2 sec run at crank, then shut off, do not come back on for 5-10 sec. like they should). They DO come on for about 15 sec. AFTER THE KEY IS TURNED OFF and REMOVED. What now? Any guesses? <als> __________________ '98.5 2500 - bone stock w/added fuel pump, filters, gauge, boost gauge.

Are the starters for 12v and 24valve Cummins the same?If not, what are the differences?Also, is there any benefit to replacing the stock NipponDenso with a Delco or other brand?TIA<als>
