I would consider changing the engine coolant temp sensor. It is located just above the center of the water pump. This sensor tells the computer the engine is cold and thereby pulsing the fuel injectors to increase more fuel, acting as a choke
Hope this helps.

2000 astro van hard to start when engine is warm

You will need to figure out if it is lacking fuel pressure or spark to the plugs when it fails to start. The problem could be a relay, coil, or several other electrical problems.
Usually, if the engine is hot when the problem occurs, and letting it cool down will allow it to start again, the cause is electrical.

I have a '98 Astro van that starts fine when cold but is hard to start win hot. It idle and runs fine. After it cools down completely, it will start OK. I was told it could be a fuel pressure problem and...

I agree, replace the Coolant temp sensor, it will have 2 wires going to it, Not 1. Usually located just behind the breather near the thermostat outlet.

This sensor controlles your timing and fuel to air ratio.

My 96 astro doesnt is slow starting when cold.

If you mean in cold weather try a winter blend oil and allow your van to warm up a little 5 minutes before driving.

Thank's for you help,astro 96 driver window work's when she want.Most of the time stop 1/2 way and after minute is working normal.And again and again.thank's for you help.

Had same problem for passenger window. A friend suggested it was likely a transistor overheating ...either transistor going bad or some other electrical problem causing the problem. Motors are essentially sealed units...not readily servicable. Found replacement on line for about $30....with help of a general Astro Van service book (in most part stores) I replaced the motor in an hour or so. If I knew what I was should have taken 20 minutes. Original motor was pop riveted in place. Drilled out pop rivets and used sheet metal screws to secure replacement. Works great. Mine was a 99 Astro. Dealer wanted about $140 for new motor! Good luck.
