96 dodge grand caravan

Had a start then die. Would change the starter relay and run for a day or two then back to start/die. Just got this vehicle. Changed the cam shaft sensor., fuel pressure is good, spark good, runs some with fluid spray in air flow.

How's your injection pulse during the start/stall? Possible anti theft issue taking injection pulse away after startup. This would certainly account for how it runs on alternate fuel and has good fuel pressure.

Yes, am sure it is the anti-theft. Only I don't know what to do about it. I have changed the instrument cluster, as it was not working properly. In the manuel it doesn't even talk about the anti-theft circuit.

You could try to reset security by disconnecting BOTH battery cables and touching them together for a few seconds.

Oh, thank you for your help. I am sure it's the anti-theft. I just don't know where to go from here.Before I started changeing parts, (I know), I would swap the starter relay, near the battery, and it would run for maybe a day maybe two. I have done the battery cable reset. I've changed the instrument cluster and the cam sensor. I am pretty much DONE with buying parts. The lock mechanism, in the lift gate, does this growl thing and won't unlock right away. I have to continue to unlock it. I tried disconecting that. Nothing.
