If the engine turns rather freely and not hindered by malfunction of pump, then it should start. Since you are going to rebuild pump, you should just remove the pump from the engine now and set it on the work bench to prevent any further damage. It is a good idea to test engine before you spend any money on the pump. Dewalt service center has all the parts lists for your machine, however you should look up the model number of the pump itself (stamped / tagged on body of pump) and look for more information from mfg. web site. Good luci

2005 Buick Lasabre 3.8 engine. Engine light stays on,had it checked,code C1276 came up.In layman terms what can the problem be? Thanks

Requested Torque Signal Circuit Malfunction
DTC C1277 or P0856 in Antilock Brake System

The electronic brake control module (EBCM) and the powertrain control module (PCM) simultaneously control the traction control. The PCM reduces the amount of torque supplied to the drive wheels by retarding spark timing and selectively turning OFF fuel injectors. The EBCM actively applies the brakes to the front wheels in order to reduce torque.
The EBCM sends a requested torque message via a pulse width modulated (PWM) signal to the PCM. The duty cycle of the signal is used to determine how much engine torque the EBCM is requesting the PCM to deliver. Normal values are between 10-90 percent duty cycle. The signal should be at 90 percent when traction control is not active and at lower values during traction control activations. The PCM supplies a pull up voltage of 5 volts that the EBCM switches to ground to create the signal.
The PCM sends a delivered torque message via a PWM signal to the EBCM. The duty cycle of the signal is used to determine how much engine torque the PCM is delivering. Normal values are between 10-90 percent duty cycle. The signal should be at low values, around 10 percent, at idle and higher values under driving conditions. The EBCM supplies a pull up voltage of 12 volts that the PCM switches to ground to create the signal.
When certain PCM DTCs are set, the PCM will not be able to perform the torque reduction portion of traction control. A serial data message is sent to the EBCM indicating that traction control is not allowed.

Conditions for Setting the DTC
One of the following conditions exists:
• The EBCM detects that delivered torque signal is out of the valid range.
• The EBCM does not receive the delivered torque signal.

Diagnostic Aids
The following conditions can cause this concern:
• An open in the delivered torque circuit
• A short to ground or voltage in the delivered torque circuit
• A wiring problem, terminal corrosion, or poor connection in the delivered torque circuit
• A communication frequency problem
• A communication duty cycle problem
• The EBCM is not receiving information from the PCM.
• Loose or corroded EBCM ground or PCM ground

Install a scan tool.
Start the engine.
With a scan tool, observe the Delivered Torque parameter in the DRP/ABS/TCS data list.
Does the scan tool display the specified value?

What must a Tata Telcoline head be Torqued.

When doing major engine work a shop manual is essential, as it is not just the torque value, but sequence that is important. Further, many newer engines use head bolts that must be replaced, and torque values now may include degree angles for final tightening.

Need service information to conduct a thermostat replace ment on a VY series 2 commodore which has the supercharged buick 3.8 engine

Sorry Graham, it is based on a Buick, the big difference is your 3.8 does not have a distributor at all, no where for it to go even, you have to start with your fan belt using a 3/8 drive bar that fits into the flexible belt tensioned, then remove ALL the plastics from the front of your engine, the water pump is under them, not a nice job so I would look at replacing any belts bearings and seals as you go

I need the torque settings for a HD 1450 motor

If you need the torque values for a particular item, I may can provide that but I cannot provide ALL the torque values for the engine as there are quite a lot of them. If you need that level of information, I'd suggest the purchase of a service manual. I understand that coming to this site is to obtain information but I simply do not have all the torque values for these engines. I specialize on the older engines like the Panheads, Shovelheads, Ironhead Sportsters and the Evolution. I do not work on Twin Cam engines but some of the torques values are the same and I can provide those. Other setting, particular those in the cam chest, I do not have. Sorry.

Good Luck

Having trouble getting my car started and keep it running

  • ;-------------------------- open up your hood and look for the idle and adjust it carefully little by ==============little and try starting your vehicle but if not, have your battery test first-------------------------------if it is producing enough voltage. ( battery maybe dead) . also try buy new sparkplugs and install it follow guidlines for torque tighting. also other option is distributor cap .

  11. Remove the No. 3 engine mount.
  12. Remove the timing belt.
  13. Remove the timing belt tensioner.
  14. Remove the water pump.

  1. Installation is the reverse of the removal procedure, while using the following torque values:

    Water pump bolts: refer to the illustration Crankshaft pulley: 130-138 ft. lbs. (180-190 Nm)

3.8L Engine
  1. Before servicing the vehicle, refer to the precautions at the beginning of this section.
  2. Record the radio anti theft code data.
  3. Drain the cooling system.
  4. Disconnect the negative battery cable.
  5. Remove the accessory drive belt. Remove the water pump pulley.
  6. Remove the water pump retaining bolts. Remove the water pump from the vehicle.

To install:
  1. Installation is the reverse of the removal procedure.
  2. Reprogram the radio anti theft code data.
  3. Be sure to use a new water pump gasket. Torque the retaining bolts to 16 ft. lbs.
