Anyone know the most likely cause for this issue? Just showed up today.

Oh... and I upgraded the sparkplugs to NGK irridiums. I've driven the van very little, and so am not very familiar with it. Really today is the first drive I've taken in it since I drove it home two months ago (100 mile trip, no issues.) I should note that it was very humid, and sometimes rainy, today, which lends credence to the distributor cap theory.longyard said:Just completed:NY Safari TONKA said:What was the last things done to the van?... :shrug:
1. power steering pump
2. Water pump
3. Fuel pump
4. All new fuel lines
5. New harmonic balancer
6. New radiator
7. Upgraded alternator to 200amp
8. New idler and tensioner pulleys
Thanks Gill. I'm going to get a new coil to add to the new distributor cap I bought. Is it hard to change the coil? Thanks. Billgillbates said:I had the same problem whenever it rained. Changed the cap and rotor but it still kept refusing to start in wet conditions. One day when it wouldn't start I pulled the dog house and cranked it. I heard an electrical clicking. When I looked at the engine while cranking it I could see a little lightning bolt shooting across the top of the coil. I replaced that and was good to go. I'm not saying you need a new coil, but I think it would be worth it to pull the cover and crank it on a day when it won't start.
Sounds like I know what I'm doing this weekend!Leeann_93 said:Nope, easy-peasy.
Okay. Can you tell me if timing the beast is as simple as lining up the marks on the timing cover and the crank balancer? Those are the only marks I see.NY Safari TONKA said:Ok look here make sure your timing its god chk complete w/Tach....if problem still CHECK YOUR CRANK SENSOR :wave: ...Let us know how it goes....You can chk the voltage on the sensor (at connector Pink or Lt Green wire) w/key ON car off should have about 11.5 Vlt...if any chk blown fuse + wires...
I've got a 2001 and the distributor doesn't look like any HEI I've dealt with before. I don't mind replacing parts on a vehicle that's got all it's original stuff after 130K and long exposure to salt on the roads from upstate NY. (I'm down here in NC.)NY Safari TONKA said:Can you put up a pic (distributor area) to see for sure what systm you have if EDI (no timing)...if HEI (timing)...I blv after 1995 was the EDI...the misfire it signal by the Hall Effect
Phantom said:P0300 random misfire can be several things that can cause a cylinder not to fire , with the astro it was very often ignition , the distributor vent screens being plugged up or the dist cap because of the short cap and not enough ventilation , this was the case so often that GM issued a Technical Service Bulletin for this
I have uploaded it many times in the past , but the site still has problems uploading now so here is the text of the TSB without the pic :
Phantom,
THANKS SO MUCH!!! for posting the bulletin. This weekend I changed the distributor cap, scrapped clean the rotor tip clean, and changed the coil. I could not find the vent screens. Where are they?
Thanks so much,
Bill
