Car will start and run for approx 2 minutes then dies. CCRM was chattering, so I replaced it, still the same. Then I found a coil that was cracked at the connector, replaced it, still the same. Car will only start if I disconnect the battery overnight, then reconnect. Battery voltage is good, fuel pump has good voltage and seems to be working since it starts the next day (?), And all fuses are good. I am going to check IAC and update. Any ideas?
Do you
have the same problem?

Sir
Let's start by checking for battery drain. Disconnect the negative cable put test light in between the negative cable and negative battery post-Is the test light On? If so start removing fuses one at a time the fuse that turns off the test light is the trouble circuit that's draining the battery. No battery drain-check the fuel pressure and give me the readings.

Ok, did battery test and when I first put the tester on I had 10v and it slowly crept up to 11.3v and held. Pulled all fuses and relays under the hood in the main fuse block and no change. I did not pull the fuses inside of the car. There is a viper alarm and aftermarket radio, but the radio is wired into the factory harness. Next, I checked for fuel pressure, NONE. Thought that gauge was bad, but only a few drops when I disconnected gauge and pushed in on test valve. Also, now my theft light is blinking on the dash and that last for about 2 minutes, then it dings (like when you have the door open), then the theft light flashes about once every five seconds. I'm not sure if it is reading my key. I may buy a bypass kit and see if that resolves the problem. I also cleaned the MAF and IAC.

3Volts is not enough to power the fuel pump.

Also the battery is in good shape if it has a 12.4 volts or better open voltage.

I was hoping that you may have some insight as to why sometimes it runs and sometimes it does not. Is a small amount of fuel getting to the fuel rail and lets it run until that is depleted? What are your thoughts on the theft light? Also, I noticed tonight that the CCRM was chattering again.

Next, I checked for fuel pressure, NONE. When you turn key to run positiion do you hear the fuel pump come On. If not check the fuel pump relay and inertia cut off switch then comeback

So the weather finally broke and was able to work on the car today. So I want back to the basics. I did not hear the pump kick on when I turned the key. So I checked for voltage again at the pump, 3v. So, I went back to the fuses and as I was checking them, the CCRM started chattering again. Now, being an electricain, I knew that the relays weren't getting enough voltage or there is a ground issue. So, I let them chatter while I went to every wire and connector I could find. Low and behold, the connector for the ground to the main fuse block was bad. Went to the parts store, got one that would work and BAM! It's fixed!!!!!!!!!!!!!!!!!!!!!!!
Thank you for all your help, I will tell everyone about the site and to donate.
Thanks again for all the help!
