Hello friend Carlos my name is Alberto Salinas and I have a Caravan 2001 with the same problem, and I would like you to help me if you could already repair that fault, which was what I had. Because just like you in my caravan if there is pulsation but there is no spark, I change camshaft sensor, crankshaft position sensor they checked and it's fine, the computer is well already checked and it is fine, coil changed and still does not stop, well it does a rare fault starts but I turn it off and the thing of 10 minutes and it no longer starts starting, that they will have to start, they will have a fuse, they will have a fuse. I'm already desperate I don't know what to do. FRIEND PLEASE HELP ME, WHICH I HAVE THE CRUITTE EETRER. I am from Pachuca Hidalgo, please thank you for your great help. Thank you very much I leave you my email if you would have a moment to send me an answer you did, I like a great and cordial greeting. Hopefully and you can answer me.
