Ok moisture can cause problems with gas and spark. try some dri gas or something first, check the fuel filter. or somekind of timing with the injectors and the ignition switch.

95 chevy blazer 4x4, 4.3, v6, tranny fluid flows out top of fill tube. I have changed the filter and no I did not overfill it. Starts right up even when cold, but starts losing fluid right away (drove...

There should be a vent tube on your transmission. Check to make sure it is not plugged. Did it do it before you changed the fluid and filter? To properly check fluid level the vehicle needs to be running and warm and in park on a level surface. Just in case you didn't already know. IF your vent tube is open and fluid level is correct you must have internal problems.

1999 chevy blazer many wires attach to it? i thought there were 3 when we disconnected it but now can only find 2. help plzzz

do you have 2 wires , plus the positive battery cable, if so , i believe the 2 wires went to the solenoid, if you only had 1 wire and a positive battery cable, then the 1 wire went to the solenoid, and positive cable went to the starter.

Wont run

Since you reworked the top of the motor, I would look real hard at the timing. Since it almost caught, I am assuming you are now getting spark. If not, look at the fuse for your computor. A fuse can blow just cause it's in the mood and no other reason. Keep in mind, it's either mechanical or electrical. You may have fuel, but is it at the right pressure? Change the filter as a precaution.
Good luck

Wont run

Try checking those sparks again. It could be a weak spark not enough to start your engine.
Make sure also that you have fresh gasoline, as gasoline or diesel looses it's effectiveness after a long time.
