2001 silverado 2500hd LT 6.0 L v8 gas does anyone have the ECM pin out diagram.also I have read there is a fuel module or some kind of module above spare tire I've looked and don't have one .is there a reason why

thank you

 

2001 is to old for a fuel pump control module....you will have a fuse and relay in the ubec to power the fuel pump.

post the specific circuits that you need for a pinout.

 

I have crank no start issue I think it might be anti theft/passlock but I'm getting pulse at injectors(noid light test .and injectors 013 ohms .been three months no ride at a point dont know what to do. but pin out on anti theft /passlock and injectors gotta find problem

 

if you had anti-theft failure, there would be a warning light in the cluster, and no injector pulses.

have you tried using starting fluid to start it?

 

yes and it starts then

 

try measuring the fuel pressure

 

ok I will check it this morning
Thank you so much for your help I'm at my wits end .I truly appreciate it
