Hey out there my truck is still down and I have no idea what to do. Again the problems are mulptable.
1 front turn signel and 4 way lights dont work but the rear do and the running lights work. bulbs good, fuses good, I am tying to trace the wire but do not know how it runs and the diragrams are not accurate. also the temp and gas gauges do not work and I replaced them with a junk yard set as well as the board on the side of the dash but no change.
2 truck runs rough at idel like it is not warmed up. tries to stall then when going around 60 mph the service engin light comes on until I slow down for a little time again. replaced air filter, fuel filter, pcv valve and have checked all the vacume lines and nothing do not trust codes with electrical problems. aslo the abs light comes and goes. I put new brakes all around but I have not done a fluid change. I got this truck used so I do not know the history and I am at my wits end.
 






maybe your computer is not getting full power...saw that in a another psot
 






Well, I'll run down a few rough ideas, this is pretty sketchy for me but I see no one has really chimed in with help.

1) Check your battery voltage. anything over 15 is bad news. Anything lower than 10 is aswell from my expiriences.

2) Get a new PCM.
Probably ruined. The battery is just a "maybe".

Make sure that if you get a new PCM you get the security module that goes with it or can have it re-programmed to run without one/new one.

Just my 2cents, I can't see the truck myself, so I'm not liable if I'm completely off.
