Chevrolet Repair: 1990 suburban 350/th400, diagnostic work, test light

Question
Hello. The engine turns over but does not fire. the dash, dome and headlights don't work as well. I have reset the computer, this seems to work only for a couple of on/off cycles. The battery is new. where do i go now? Thank you.

Answer
HI GARY,THIS WILL TAKE SOME DIAGNOSTIC WORK, WHEN THE ENGINE IS CRANKING OVER CAN YOU CK OR DO YOU KNOW IF THERE IS SPARK [IGNITION] AND OR FUEL..CK THIS OUT AND GET BACK TO ME. IF YOU DO NOT KNOW HOW TO CK THEM I WILL TELL YOU HOW.. WHEN YOU SAY RESET THE COMPUTER YOU MEAN CLEAR CODES ??? AND THEN AFTER CRANKING OVER A WHILE IT SETS CODES AND IF SO WHAT ARE THEY..ALSO DOES THIS HAVE A AFTERMARKET ALARM SYSTEM ??? AS FAR AS THE DASH ,DOME AND HEADLIGHTS NOT WORKING THIS SOUNDS LIKE A FUSEABLE LINK DOWN AT THE STARTER MAIN PLUS CABLE GOING TO THE BIG POST ON THE STARTER NEXT TO THE MAIN BATTERY CABLE .CK THAT THE FUSEABLE LINK IS NOT BLOWN. YOU WILL NEED A TEST LIGHT OR VOLT METER. SHOULD HAVE BATTERY POWER BOTH ENDS OF LINK...GET BACK TO ME..
