No crank

Yes sir

 

Ok lets check the fuel pump circuit, unplug the fuel pump resistor (small finned silver box with 2 wires) in front of the battery and check for power on the Black/Red wire while cranking.

 

New switch completely installed no more security light still no fuel

 

Ok resistor has power while cranking

 

Ok can you tell if the fuel pump is running or not while cranking?

 

No fuel pump

 

Ah, have someone beat on the bottom of the tank while you are cranking and see if it takes off.

 

Pump is running inside the tank for a few seconds after cranking

 

I'm assuming the truck has gas in it?
Have you checked power and injector pulse at one of the injectors?

 

No sir can you tell me how

 

can you access any of the injector connectors to unplug it? I can't remember how hard they are to get to.

 

No I can’t see any they are under the plenum

 

The only other place to check them is at the PCM, you could pop the fuel line off and see if you have fuel there while cranking but without hooking a hose to it to put in a container it would be quite dangerous to have fuel shooting everywhere. It would be best to use a gauge to check fuel pressure though.

 

I pulled the fuel line off in the engine compartment and cranked and had fuel coming out of the line with pressure

 

Well we can check the injectors at the PCM Connector E12:
Should have battery voltage with the key on.
Pin 1 (Black) Injector 2
Pin 2 (Green) Injector 4
Pin 3 (Blue) Injector 6
Pin 6 (Red/Blue) Injector 1
Pin 7 (Red) Injector 3
Pin 8 (Yellow) Injector 5

 

No power on any of these

 

Ok check pin 6 (Black/Red) at the ignition switch for power.

 

Got power there

 

I'm thinking we will have power there since we have power at the coils.

 

Ok go to connector EA1 in the engine bay fuse box and check Pin & (Black/Red) for power.
