2001 Caravan runs 2 seconds and dies
I can restart over and over and it always runs for 2 seconds and then dies. If I step on the accelerator right when it starts then it will stay running, but it is like the ignition cuts out very briefly every 2 seconds. When you get in and turn the key on, you can hear the fuel pump run for 2 seconds, stop briefly and then run for 2 second, this repeats indefinitely. I believe that I have a bad ECM, I just want to exhaust all other possibilities before I purchase a new one. This van is a very basic model and does not have a chip in the key. I have also checked the solder joints in the instrument cluster, tried a new battery, and cleaned the connections to the fuse box. The engine runs smooth for the 2 secons it runs. If you take it out and drive it, it even shifts fine. Just that the ignition cuts out briefly. Any help will be greatly appreciated.
