I'm 22 I own a 2001 Tahoe z71 (5.3 V8) 140,000km bought it off my dad who wasn't around much to use it. Winter is setting in hear in canada my tires and ride were getting shaky I brought it in to my local indie all makes type guys to see what was up an alignment etc. Turns out I need to new rubber and I was driving on some dangerous tires so I left the car there for about 5 days while we waited for tires we ordered. I gave them the car with a little less than quarter tank I think the owner test drove it too before they looked at my tires assuming I had already checked them so now assuming they used a little gas while they had it there I guess it was low i'm not sure.I got to the shop tonight they just got my rubber on we went to start it it seems to get no fuel to it so these guys see some old remote starter that the first owner must have installed these guys assume its some gm security thing so they unplug the battery try pulling some tricks with the keys they had the doors open the whole time I think I why they kept complaining about the security flashing light which as I remembered was normal they took out the whole wiring for the remote starter and restoring my wiring back to oem state. The we try again no luck still not getting gas so hes looking at the fuel gage it sitting on no gas they tried to start the car about 7 times before this. We add gas not very much though and again no luck so one mechanic bangs on the fuel pump area with a hammer as the other turns the keys and it starts 10 secs and dies. They say its my fuel pump they were asking me if I knew about a relay or emergency fuel shutoff I am not sure looking for an answer to that. They then say they think its the fuel pump I read about having 6 gallons if its dry to start it gonna try that. I called them tonight and told them to try it well see tomorrow. Apparently there is some electronic thing on the pump that could have been disconnected or died as you can see I don't now much and I need some help not looking to replace the fuel pump for fun. What are the proper steps to diagnosing this could this be electrical? The security light stuff I dont get? Anything you answer I will forward to my mechanic steps to diagnosing the fuel system or other issues etc. They are quite capable of the work.
have the same problem?
