No start

I have a 2002 Tacoma. Today I hit some washboard road and truck died. Now the truck will start and die. I checked and replaced the fuel filter. The fuel pump will pump fuel while cranking but nothing with the key in the on position. Any ideas on what to check. My guess is something like a loose connection and the bumps caused the bad connection. I don’t know where to start.

 

Check that all your wiring harness grounds are properly tightened.

 

Does that year have the collision fuel pump shut off?

 

The fuel pump only turns on when there is a crank signal.
So that is normal.

Let me look at some diagrams

 

What engine and transmission?

 

Engine is 3.4 v6 I’m not sure the transmission at the moment.

 

Is it Auto or manual?

 

Automatic transmission

 

How long does it take before the truck dies?
As soon as you stop cranking, or a few seconds later?

 

Automatic

 

Does as soon as it fires up. And I stop cranking.

 

If I try starting it again it only cranks, but if I shut the key off and try again it will start and die again.

 

Thank you for your help!!! I figured it out finally, the front coil pack came unplugged. Plugged it in and truck runs great again.
