Random Starting

We have had rain here for the past few days and my astro has not started since. I have checked the distributor cap and did not see any moisture. I still have my receipt from buying the cap, so I exchanged it and the rotor button and picked up plug wires. It still will not start. Do you have any other suggestions?

What I always did for a no start when wet problem
remove all engine covers on a DRY day
then run engine, and use a pump spray bottle with water and mist the ignition ONE part at a time
you will find the faultly part it will start to miss fire or totally stall
BUT dont spray the mist on all the parts at the same time, Only one at time
this method works all the time U make it rain
electricity will jump and short out easier with a mist than solid wet, if U turn a hose on it, it may run OK, try this method it works

Just wondering if you checked the fuel pump psi, fuel pressure testing guage hooks up to the fuel pressure regulators like a bicycle conector turn the engine over you need 55psi to open the regulator. I have change one pump on my old 89 400k+ and four on my 96 340k+ sometimes it works intermitently sometimes it dies completely two tricks I have tried one you bang under the fuel tank with a rubber malet (in the center where the pump is located) to jar the pump sometimes it workes sometime it won't at best it might get the van started but next time it could fail again. The second trick was to short a red wire that is protruding out of the wire harness by the battery (you know the little wire that you were wonder what it was for) a very quick touch on the positive post sometimes jumps the fuel pump to allow you to start (caution though too long of a touch will fry the wiring harness for the pump in side the tank, bin dare done dat). I was told by a couple of mechanics that after market pumps last about 18mths and the three I put in were almost to the day of 18mths. THe last one I put in was a GM part and it lasted the longest so far and was $30 cheaper.

Hope this helps.
