Battery tests good and is new. Once jumped I removed positive battery cable and continues to idle fine. Drove for 20+ minutes and park; try to start and it just won't.

You can take out every computer in the car in a heartbeat.. You may have a parasitic draw. There is a procedure for finding a battery draw like that. You will need a digital ammeter and a jumper wire with clips on the ends to do this. First rig any door switches so you can have a door open without triggering the interior lights and unplug the hood light. Remove one battery cable and attach the meter in series between the battery cable and battery post. Take the jumper wire and also attach it the same way. Leave the jumper wire on for at least 10 minutes to expire all the automatic timers. Now remove the jumper wire and read the meter. Anything over 50ma is too much draw. The way you locate this is to start removing fuses one at a time until the meter drops to normal level. This will be the circuit with something staying on. Determine what components are part of that circuit and check them individually until the problem is isolated. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Could that possibly be drawing? I don't have an ammeter on hand and just seems like problem has been since window has been effed? Hammer Time Ultimate Carjunky / Moderator Apr 27, 2011, 12:59 PM Post #4 of 6 (1756 views) Re: 94 Suburban won't start Sign In That would probably cause interior lights to stay on. You're not going to know unless you run the tests. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional. Spartasotan New User Apr 27, 2011, 1:02 PM Post #5 of 6 (1752 views) Re: 94 Suburban won't start Sign In What if I pull the fuse, jump it and see if it restarts? The fuse cuts the circuit, right? Hammer Time Ultimate Carjunky / Moderator Apr 27, 2011, 1:04 PM Post #6 of 6 (1749 views) Re: 94 Suburban won't start Sign In You're not going to know what fuse is powering the draw or even if you have a draw unless you run the tests. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
