cranks but no start

Hi,

Is there anything electrical on the vehicle that works? For example, do the headlamps work or the brake lights?

I attached a pic below showing there are two main (250 amp) fuses between the battery and the fuse boxes. Have you checked them? Also, are you certain the battery is good and the terminals are clean and tight?

Do me a favor. First, check the battery terminals first. Always start at the power supply (the battery). Here is a link showing what to look for:

If the battery is good, then move to the two main fuses I mentioned. In addition to checking if the fuse is good, confirm there is power to and from the fuse. Here is a link to help:

Try this and let me know the results.

head lights work high and low . no high beam indicator heater and radio power up crank good but cluster completely out no spark. all 5 fuse boxes have power at the fuses. wipers work no fuel pump cycle on key up or cranking none of the gauges function. ECM act like not powered up.
don't know where any mega fuse is on this, tried to check ignition switch but wires are small and don't have large wires like a normal vehicle.. does ECM and cluster have the same relay to power up system?

fuse okay. i have power to all five fuse boxes. looking for ignition relay or ECM relay location and wire diagram may help.

Hi,

I attached the powertrain management wiring schematics and legends. This is from the manufacturer and is a bit difficult to follow. If you have any questions, let me know.

See pics below.

need number of components id.. looking for ignition switch, cannot locate.

Hi,

I attached two pics below. The first one is the ignition switch ground circuit. The second is the ignition power circuit.

Let me know if this helps.

Hi,

Let me know what is decided or if you have other questions.
