Engine will not crank over - Starter not working?

Hello,

This sounds like the TIPM has failed. This guide to check and the relay location is in the diagram below with the starter wiring diagrams so you can see how it works. The TIPM will need to be programmed according to the instructions but I have heard guys replacing it and it self initializes. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Hi,

If the battery dies with the engine running after 20 minutes, the alternator isn't working. The first thing I want you to test is the alternator. Follow this link:

Here is a link that may help with the test:

Now, since the alt is new, if you are not seeing it charging, there may be a problem with the voltage regulator. This leads me to the next step.

If it isn't charging, remove the alternator and have it bench tested. If it works and tests good, the problem is the regulator which is integral in the power-train control module. Thus, the PCM needs replaced.

Let me know what you find.

Hi and thanks for using 2carpros.com

This type of problem can be related to many things. First, take a look through this link. It shows how to determine if the starter is getting power at the right places at the right times.

Perform that test. If there is no power to the smaller wire on the starter when the key is in the start position, you need to check the totally integrated power module (TIPM). These modules are pron to problems because there are so many connectors in the pins that attach to them. Often times a pin will break or corrode and no longer supply power.

I attached a schematic for you to see. I had to break it in half so you could see everything. If you locate the starter in pic 1, you will see a yellow wire that runs from the starter to the TIPM. The TIPM is shown in pic 2. What you need to do is check that wire and where it attaches to the TIPM. However, before you disconnect any of the connectors on the TIPM, disconnect the battery and allow at least 10 minutes to pass before you proceed.

The TIPM is located near the battery and appears as a fuse box on top. Picture 4 below shows it. Again, make sure to disconnect the battery prior to working on this component.

At the TIPM, locate connector C10 which is an 8 pin connector, light gray in color. Disconnect the connector and inspect both the plug and pins in the TIPM for damage or corrosion. You will specifically check pin 8. You will need to reconnect the battery to test for power to the pin. Make sure no power supplies in the box or battery can short. Have a helper turn the key to the start position and check if there is power to pin 8. If there isn't, the TIPM is bad. However, as I mentioned earlier, most times it is a corrosion issue. If a pin is broken on the TIPM, I don't know of anyone who can repair it.

Here is a legend of pins and picture 3 shows the plug.

I realize this isn't an entry level procedure. However, if you need help, feel free to ask.

Take care,

Good morning,

I attached a wiring diagram for you to view. Check the two wires highlighted for power with the key in the start position. We are trying to see if a signal is being sent to the TIPM.

These guides can help us fix it

and

Please run down these guides and report back.

Roy

Nuts, sorry. I reattached it.

Roy

TIPM

The pins highlighted need power in the start position.

Roy

Those wires are in the same connector at the pin number listed. Look at the pin numbers on the TIPM.

Roy

Okay, check the pink/black off the ignition switch for power.

Then check the wire at the starter.

Looks like the TIPM is the issue.

Roy

Hello,

I have seen the TIPM cause this problem but to be sure let's check for power output to the starter solenoid. Here is a wiring diagram so you can see how the starter wiring works, use a test light by following this guide, test the yellow and grey wire

Check out the diagrams (Below). Please let us know what you find. We are interested to see what it is.

This furthers my thought on the bad TIPM here are diagrams and instructions to help you replace it. This unit is plug and play it self initializes.

Check out the diagrams (Below). Please let us know what happens.
