SOURCE: dodge cummins won't start, fuel reaching injector pump but no fuel coming out of injector pump.

You said you have fuel flowing from the inlet line of the injection pump? But not at the injector lines?

SOURCE: number one injector bank on 2006 dodge cummins

you'll notice on your valve cover gasket there is two connectors.. the one up front is your 1-3 the one in the rear is your 4-6... you can remove your valve cover and check the connections from the injector connectors to the
connectors on the valve cover.. check for an open.. however you could also have a fault internally in 1 of your injectors in that bank as well.. hope this info helped..

Check the fuel pressure at the filter. Odds are the lift pump, located below the filter, is toast. Continual cranking of the motor with a bad LP wil cause the injector pump to heat up and burn out. Replace the LP and fuel filter. Bleed the system by cracking the inlet to the injector pump and bumping the enigine over so the LP will run. Once you have fuel at the injector pump, crack injectors 1,3,and 4. Crank the motor for no more 6 or 7 seconds at a time until it turns over. Give the pump time to cool for a couple of mintues between cranks. This process is easier with two people, one to crank and the other to watch for fuel and tighten the injectors once it starts. If the injector pump is fried at this point from cranking with no fuel, the motor should idle, but will stumble all over itself when the throttle is applied.

SOURCE: 99 dodge 2500 5.9 cummins fuel pressure at 3psi

The 3 psi is caused by a failed transfer pump. The problem the loss of could be the VP44 injection pump. This pump should be run at min 7psi. I had the same fuel pressure problem. I replaced my stock transfer pump with a FASS DDRP from www.usdieselparts.com. The stock pump is over $200 to replace and will fail again, sometimes right out of the box. The DDRP will supply about 15psi to the pump and is simple to install. I hope this helps.

What is the location of the fuel pressure sensor on a 2000 FORD truck f650 5.9L
7th generation truck, Cummins.
Cummins ISB 5.9 L inline-six

it is the fuel fume WC super low pressure sensor on top of the tank.
part of the EVAP SMOG systems. for Vent fumes. not fuel raw.

there is fuel level sensor too.

why not tell the problem first, so we can not have to guess 3000 parts in the the truck not working right.
as in whats up doc
getting DTC errors for EVAP
engine lost power, or DTC errors for EFI? or?
OK I found the engine controls schematics on this truck
and I am looking for all sensors (for sure pressure)_
map pressure switch sure. is vacuum not pressure unless boosted induction.
yes ICP is there injector control pressure sensor true name.
I read all 16 PCM pages. so you are talking ICP
the SM says

DTC P1280 indicates injector control signal circuit out of rangelow was detected during KOEO Self Test or during continuous diagnostic monitoring.
and

  • biased ICP sensor/PCM
  • open ICP sensor circuit
  • short to SIG RTN or PWR GND on ICP sensor circuit
  • open in VREF circuit
  • Disconnect ICP sensor harness connector.
  • Key on, engine off.
  • Measure voltage between VREF Pin B and battery ground.
Is voltage between 4.5 and 5.5 volts?
then goes on 25 lines of tests and pages. just for this.
I say RTM read the manual and do the 25 tests above

Sounds like a faulty fuel pump, engine will run on 40 psi of fuel pressure but requires 60 to 70 psi to start if engine has fuel injection. hope this helps.

Changed computor wont start
FIRST CHECK YOUR FUEL PUMP TO ENSURE IT IS WORKING PROPERLY, THEN DO A FUEL PRESSURE TEST. AN AVERAGE READING WILL READ BETWEEN 15 AND 30 LBS. THEN YOU NEED TO BE MORE SPECIFIC IS IT GAS OR DIESEL IF IT IS A DIESEL THEN YOU NEED TO LOOK INTO INJECTOR PRESSURE THE AVERAGE CUMMINS COMMON RAIL PRESSURE AVERAGES AROUND 5,000 TO 8,000 PSI ANYTHING LESS THAN 5,000 PSI THE TRUCK WILL NOT START OR WILL BE HARD TO START.

2006 dodge mega cab 4x4 cummins w/6sp started fine this morning and now it will not start about 2 years ago the same thing happened and had to reprogram something, it had something to do with the starter...
Your truck needs to be hooked up to a scan tool so the common rail fuel pressure can be checked.
Have you checked to see if your fuel lift punp is operating to transfer fuel from your tank to the high pressure CP3 fuel pump?
Could possibly be the FCA (fuel control actuator) located on the back of the CP3 pump. It controls the fuel pressure in the high pressure fuel system.

Bad Injectors are also a known cause for no start on these trucks.

WARNING!!!!!!!!!!!!!!!!!!
Do not unhook any fuel injection lines from the CP3 or Fuel rail or Injector cross over tubes while cranking or running as this fuel pressure varie from 4000 psi to 23000 psi when running.

A final addendum to the 1996 dodge dakota...
Here's the procedure for checking the fuel pump. I would 1st change the fuel filter, 2nd would be to scan for engine codes (free service at most parts stores), then check pressure (on a cool day, below 70 degrees) Good luck, let me know what u find. Curt
FUEL DELIVERY 1996 Dodge Truck Dakota 2WD 2.5L SFI 4cyl The Fuel System Pressure 44-54 PSI (Pounds per Square Inch)

Vent the fuel tank vapors by loosening the fuel cap and unplug the injector wiring harness from the main engine wiring harness. The next step is to attach an electrical jumper between a solid ground and the fuel injector terminal pin number 1. Next, connect an electrical jumper between the battery positive post and injector terminal pin number 2 for a period of time not to exceed 4 seconds. This serves to bleed down pressure from the fuel system. Install a fuel pressure gauge on the fuel rail service test port and energize the fuel pump. This will bring the system to a stabilized fuel pressure that can be visually verified on the gauge.
