Open Question

My truck will not start, was fine one day, and next will not start. what could be wrong?

Went out to start truck but will not start. It will not turn over. Power windows and locks do not work. Headlights only work on low beam. The signal lights wont work nor the 4way flashers or brake lights and also the gauges do not work. Have cleaned battery cables, checked fuses, battery is ok. the engine turns over when I cross the solenoid switch. fuel pump starts.

SOURCE: Engine will start and rough idle but dies when either the brakes are applied or the lights are turned on!

have you checked out your fuel filter? I had my 2003 denali do the same type of problem and it turned out to be a very dirty fuel filter.

SOURCE: shuts off while driving. no fuel pressure. pcm fuse blows/ fuel pump relay inserted.

Sounds like the fuel pump is shorted.

SOURCE: brake lights wont turn on.1994 gmc sierra.

This may sound too simple, but first verify that you are getting voltage to the light socket. Use meter on d.c. If you are getting voltage, and your bulb is good, it could be a bad ground. Don't overlook the brake light system goes through the directional signal in the steering column.

SOURCE: no brake/hazard lights,have running/turn signal lights

Suggest you change hazard flasher 'can' first, then go to the hazard switch. I'm betting it's the flasher can.

SOURCE: 1987 GMC sierra , no fuel pump power.

The inline fuel pump fuse on the passenger side firewall is good? Are you jumping it with 12 volts at the test lead or the fuse?

The charging system on your vehicle is computer controlled . Your vehicle is a rolling computer .The instrument cluster has a microprocessor inside , there is also a body computer ( SJB ) smart junction box , Engine computer etc... they all communicate on a serial data network , C.A.N - controller area network . It's hard to know what's wrong when you don't know how it works . There could be codes stored in the computers , these will not always turn on the check engine light .

You have two pumps,I guess you know that ,if you already did one. Did you check fuel pressure at the rail and check out the electronic pressure regulator? What codes are coming up and do they stay set?

My car ran fine but all at once it started missing and the ioling would go up and down...then when i went to start it the next day it would turn over but wont start 99 saturn station wagon


It seems like a bad idle Air control Valve or an Idle position sensor. The best way is to get a trouble code for free at most autoparts stores and they will tell you what might be wrong.

Check your battery terminals. They may be corroded or just loose. If you get it running again have the battery and charger tested at an Advance or Autozone.

Hope this helps.
