SOURCE: 97 isuzu trooper. Starter motor has no power.

Check the battery and cables going to the starter. Weak arc? Possible that the relay needs to be rechecked now. The inertia switch may also be a possibility. Has the car been in a recent fender bender?

Not really familiar with this vehicle, but being a 2004, probably does't have an injection pump.Probably a common rail, with a hight pressure oil pump. Best to have it checked by qualified diesel tech as replacing parts can be time consuming and expensive.

SOURCE: my isuzu dmax oil pan

In order for that dent to have any real effect upon oil delivery, the dent would need to be perfectly flat up against the oil pump pickup. Chances are it isn't. The pickup in most pans is located a bit above the pan bottom to lessen the chance of ingesting any contaminants (sand, grit, hard carbon etc). With the clearance diminished, chances of that are greater.
While only oil pressure is measured, volume is also important. With the pan that close to the pickup, pressure probably won't be a problem but you may loose some volume (impossible to tell how much).
When I put together a fresh engine, I like to see pressure of about 40psi or better. As an engine wears, engineers claim that anything above 15psi is OK...I use a higher number of 25psi (at idle) as a minimum "safe" limit. Anything below that, you know you have a problem and it's wise to find it early and fix it. (Pumps rarely fail...most low pressure problems can be traced to engine bearing wear, resulting in bleed off past the bearings)
As for your pan: If the pan is bent, and you have it off the engine, why not hammer the bend out a little? or, better yet, get another pan from a scrapyard and replace it entirely?
If you have not removed it, there's no real way of measuring and what you are seeing may not be the whole story...pickup clearance may be greater elsewhere. In that case, just continue doing regular service and save pan replacement for a day when you have time to do it.

My 2007 Uplander won't start. We've replaced to battery and starter relay. Still won't even click when trying to start.


How to voltage drop test starter motor circuit This is how a normal starting system use to work ! Not now , computer's involved , communication networks etc.....
Here is how your's works

For ignition switch power modes refer to Body Control System Description and Operation . When the ignition switch is placed in the Start position a discrete signal is supplied to the body control module (BCM) notifying it that the ignition is in the Start position. The BCM then sends a message to the engine control module (ECM) notifying it that CRANK has been requested. At the same time the BCM is supplying 12 volts for the IGN 1 relay closing it and supplying battery positive voltage for the crank relay coil. The ECM verifies that the transmission is in Park or Neutral. If it is, the ECM grounds the control circuit of the crank relay. When this occurs battery positive voltage is supplied through the switch side of the crank relay to the S terminal of the starter solenoid.

Sorry but your best bet would be to take it to a qualified repair shop ! Or the Chevy dealer . Could have DTC'S - diagnostic trouble codes stored in the BCM !

DTC P0615 Starter Relay Control Circuit

Circuit/System Verification
Ignition ON, verify that no starter relay, theft deterrent, or automatic transmission DTCs are set that would cause the ECM to disable starting.
? If DTCs are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle .
Ignition ON, observe the scan tool BCM Starter Switch parameter. Place ignition switch in the crank position, the parameter should display ON.
? If not the specified value, refer to Power Mode Mismatch .
Transmission range selector in park , verify the scan tool ECM PNP Switch and TCM IMS parameters display Park/Neutral.
? If the TCM IMS parameter does not indicate Park/Neutral, refer to Transmission Internal Mode Switch Logic .
? If the ECM Park/Neutral parameter does not indicate Park/Neutral, refer to ECM Park Switch Circuit Malfunction.
Transmission range selector in park or neutral, attempt to start the vehicle. The starter relay should click and the engine should begin cranking.
? If the starter relay does not click or the engine does not crank, refer to Starter Relay Circuit Malfunction.

Power to many of this vehicle's circuits are controlled by the module that is designated the Power Mode Master (PMM). This vehicle's PMM is the Body Control Module (BCM). The PMM controls which power mode (Run, Accessory, Crank, Retained Accessory Power, or Off) is active.

Serial Data Power Mode
On vehicles that have several control modules connected by serial data circuits, one module is the power mode master (PMM). On this vehicle, the PMM is the body control module (BCM). The PMM receives 3 discrete ignition switch signals to differentiate which power mode will be sent over the Serial Data circuits. The table below illustrates the state of these inputs in correspondence to the ignition switch position:

Where is the safety switch for a 2006 chevy malibu


Safety switch ? For what ? Park neutral safety switch ,is this what you mean ? Your vehicle not starting ? There is a lot more involved then just that switch.
Circuit Description
For ignition switch power modes refer to Body Control System Description and Operation. Once the ignition is placed in the Run/Crank position, the control circuit of the Run/Crank relay is grounded by the body control module (BCM). With the Run/Crank relay switch closed, battery positive voltage flows through it and on to the park/neutral position (PNP) switch. With the PNP switch in either the Park or Neutral position, battery positive voltage will flow to the starter relay coil supply voltage input terminal of the powertrain control module and the coil side of the starter relay. Placing the ignition in the START position sends a message to the engine control module (ECM)/powertrain control module (PCM) requesting engine start. If the ECM/PCM has determined that the transmission is in Park or Neutral and theft is not active, it will ground the control circuit of the starter relay. Battery positive voltage will then flow through the switch side of the starter relay to the S terminal of the starter solenoid, cranking the engine. For remote vehicle start (RVS) information, refer to Keyless Entry System Description and Operation.

Manual transmission. What are the probable causes of DTC P0851?


code p 0851 refers to park/neutral switch (PNP)--input circuit low===causes ---wiring---short to ground---PNP switch---ECM/TCM
with the manual transmission there may be a pnp switch that prevents an engine start unless it is in neutral and in some scars the foot brake also has to be applied
check /replace the neutral switch and check the wiring and connections for corrosion
