97 dodge ram 1500 4x4
Got a dodge ram pickup that isnt getting any power
to fiel pump , only thing that hasnt been changed is
pcm and lower half of distributer! ? Is does
distributer have anything to do with pump not
getting power , getting a code 11 !
Check the fuse of fuel pump rely under hood. This is first thing should be checked.
Everything has been changed except for whats in post !!! Only thing NOT replaced is computer & distributer !
As far as I know, fuel pump is operated by rely only, there is not any other electronic module. Ignition on, relay on, fuel pump pumping. Just connect positive and negative wires direct from battery into the fuel pump, then try to start engine. Most probably, ECM doesn't send impulses to your injectors. In this case, Engine Control Module needs to be replaced.
Have you checked crankshaft position sensor? When you have a no-start condition, disconnect the battery for about 15 seconds. Reconnect and crank the engine for 7 seconds. Now pull the codes again. If you get a code 11, it means that the crank Hall Effects sensor or its associated wiring is defective. To determine whether the sensor is bad or the wiring is bad:
locate the wiring harness connector closest to the distributor or crankshaft position sensor. With the ignition switch in the off position, disconnect the three- wire connector. Now turn the ignition switch back on and measure the voltage on the three wires at the computer end of the wiring harness. At least one of the wires should have between 7 and 10 volts. This is the power supply wire for the Hall Effects. One of the other two wires should have a voltage that is a little lower than the power supply wire. When the engine is cranked, this signal alternates between 0 and 7-10 volts as the Hall blades rotate. The alternation may be too fast for many voltmeters, but the indicated voltage will be less than the supply voltage. The third wire, the one without the voltage, should have continuity to ground. Verify this with a voltmeter. Remember that the ground wire, although it will be continuous with ground, will have some resistance in it. Expect the resistance to be somewhere between 0 ohm and few hundred ohms. If the resistance reads infinity, this wire is open and must be repaired. If the wiring harness checks out good, then replace the Hall Effects sensor.
sorry. wrong picture.
