Check for moisture in the Distributor and use a blow dryer to dry it out. You may want to consider changing your Spark Plug wires to a "Moisture Resistant" type. Please let me know if this helps you and thank you for using FixYa!
I have a 2002 Safari with around 220k miles. I went out of town for several days and when I came back it would not start. I eventually got it started after about an hour. This happened again when I did not driver it for a week. This time I could not start the van. The fuel pump was spinning and it was getting gas. I took off the engine couling inside the van and inspected the rotor and cap. They were completely corroded. I put in an after market set for less than 30 bucks and the van started right up. I plan on getting the wires and plugs replaced but I don't think I want to do that myself due to tight access. Good luck.
Hi ....... Sounds alot like you have a grounding problem on your HT leads (central one from coil esp'ly). At night when it's dark open the bonnet/hood and start the engine. Look for any sparking or arching from plug leads, coil or ignition box. Stop engine. Find where your leads come from, four will come from a central point and make sure all conections are tight. Even remove and look for corrosion, only take off one at a time to avoid confusion and when you're happy that they're OK buy some WD40 and spray near coil and over leads and allow to dry off. This will help to prevent moisture to penetrate and will cure the problem short term.
Let us know the outcome.
I have the same problem, I replaced the fuel pump. Did NOT solve it. i was told that it is a computer problem. The computer is not sending electric to the fuel pump, by cranking it several times the oil pressure builds up and will over ride the computer and send power to the fuel pump. This is a common problem on these asrto vans.
