No start, No SES, No headlights, No horn
« on: February 02, 2013, 11:18:52 pm »
Help.  Sorry to make first post like this, truck is an 87 k5.  I need to have this thing running like yesterday.

Truck ran and died as I was parking it.

Now I have none of the stuff in the title. It will crank, but the fuel pump is not running when I turn the truck to run. Jump the relay and pump runs.

So I know that the problem for starting the truck is getting power from ECM to the relay, but I seem to have no power anywehre.

All the fuses are good. I've replaced or bypassed all the fusible links....

Replaced the ignition control module.

There was an alarm, I removed it. The crazy thing was that when I was messing with that, it did go into alarm mode, and triggered the hazards while I had the truck in run, I could hear the fuel pump priming each time the hazards and headlights flashed....cant make that happen now though.

Welcome to the site from California.

Check/inspect connections through the bulkhead connector in the driver side firewall.

It's difficult to know just how much you don't know until you know it.
In other words... if people learn by making mistakes, by now I should know just about everything!!!

What do you mean you bypassed your fusible links? That's a big mistake#1. Go back and add the proper circuit protection then recheck the ecm fuses. Get rid of all of that alarm crap and rewire it accordingly then follow diagnostic flowchart A-1.

If you search cranks but will not run you will find similar posts as well
