Car intermittently starts on 2002 Chevrolet Monte Carlo

Problem began about 7 weeks ago. Car would crank, but not start. Towed it to dealer, where they said the fuel pump was bad. Replaced the fuel pump. Brought it home on Wednesday, tried to start it for work the next morning, no start again..only cranked. Towed back to dealer. The car would "supposedly" start every time for them, so they say no code was thrown. Had it 6 days on day 5, the car wouldn't start. Aha..think they found the problem a busted bolt inside a battery terminal cable.Picked up on Thursday, tried to start for work the next morning, only cranked, no start. Towed back in. Kept it 3 days, the car started each time, they say.Told me to pick it up, they couldn't find the problem. Have drivin the car a total of 3 days in the past 7 weeks. Its now sitting in another garage, where one week ago, a cam sensor was installed. It started and ran super for 1 day. Next day , cranked only, no start. My sons fiance pulled the fuel relay to check it, when she put it back in, the car cranked, cranked, cranked and then started. She says it sounds like something isn't letting the fuel pump kick on. Apparently this has stumped everybody as to what the problem is. I just want to get my Monte back on the road. Can anybody help me with this??

The security light had been coming on a couple weeks prior to the car doing this..not at the time of the failur to start.

The check engine light would come on. The dealer and the other garage say they have checked all this. But the problem is still occuring. Thanks for the help.

You need to take it to somebody that knows what they are doing. There has to be history codes stored. Just because the dealer sells them doesn't mean they know how to work on them. Have the Body Control module coded out also.
