1991 Won't Start. Please Help!
 

Hey everyone. If there is anyone out there who can help it would be greatly appreciated.
I've got a 1991, 4.9L, auto, 2wd.
Just died when I pulled it over. Tried to start it again and it just turned and turned and turned, no spark.

Changed the ignition coil. Still not starting.

I am starting to think its the fuel pump relay, or the pump itself.

Does anyone know what else I should look at, I don't want to pay for trial and error parts.

HELP!
Thanks.

Did you check the fuel shutoff switch, on my 91 it was above the parking brake, if the button is up the switch is tripped

Mechanic says its the ignition module.
Any idea how much this costs?

Less than $50.
