Truck ran after charging batt next day went to drive started then died twice then only cranks amp gauge reads nothing and fuel reads nothing. I replaced wires with rubber on solenoid checked disable links and all fuses in trk and out of trk in both boxes my boss said to wiggle the key he had to do that b 4 with this trk. I kinda scratched my head and tried it any way. So I thought maybe it the ingnition so I took one from a2000 but I think I should have takin the lil black box under the colum also but I did not. Theft lite blinks only when key is off. Hope this is enough Info thanks so much. Jeff

 

What does the theft lite do when you turn the key on?

 

Theft light goes off no gauges

 

If you have a voltmeter, check to see if you have 12 volts going to the injectors and coils with the key on. You should have that.

 

Yes I have 12 v to both.

 

Check very carefully the connections under the dash at the fuse panel.
Some of those fuses are hot all the time , others only when the key is on. Make sure both sides of the fuses controlled by the ign switch are hot with key on.
Also you can try unplugging and re connecting the plugs for the PCM and look for any corrosion on the pins.
Also double check all the fuses under the hood .
