Ok guys I've got a issue maybe you guys can help me with.
I have a 04 Duramax with only 40K miles. never had motor problems. I have the Edge programer on it since 2K miles.
I don't drive my truck every day because I have a work truck.
Up until just recently I have never had a Battery problem. My truck wouldn't hold a charge about 3 months ago. So I took my ruck to the chevy dealer and the ran some test on it and told me my 2 stock batteries were shot. They told me to replace them myself and I will save about $200.00 so I did. I bought 2 batteries from Costco and the truck batteries worked for about a month. Then wouldn't hold a charge for over 3 days of sitting.
I took the batteries back to Costco and they replaced both of them for free.
Now the truck has been sitting for about another month straight and never started. Of course both of my batteries are dead again. I went down and bought a brand new battery charger and charged both batteries completly. My truck wont start now with charged batteries.
Right now it cranks over fine almost too fast with the charger still hooked to one battery. What it will do is fire up for about 1 second and instantly shut off. If I try and give it gas it won't fire up at all. but if I don't touch the gas pedal it will fire up for a second and instantly shut down again.
I tried priming the fuel pump (right ontop of the fuel filter) and then going back and starting it but the same thing keeps happening.
I do notice that my alarm button wont work...kinda seems like the batteries still arn't doing there entire job??
What do you guys suggest??
I'm thinking of taking back these batteries and getting new ones , maybe these just don't hold a steady charge to keep the electrical running. Can something maybe wrong with my fuel injectors from sittting too long?
