Ok. Here's to the question I bought this truck rebuilt the motor put new injectors and all that jazz.

The motor is in all bolted in and hooked up. I have no power to the lift pump. SO I jump wired the lift pump.

It is a 48re truck. So i wired neutral safety switch just so it would crank.

When it starts the lights flash and the horn honks then dies after about 15 20 seconds. I know it's the security bs. But is that because the trans is out and the ECM isn't seeing any communication? I assume or should I check into something else.

I have started my 08 with no trans but it's also standard so that's alot different. Has anyone else ever started there 48re truck with no trans.

Thanks guys
