proceedure is to set timing . shut off engine , plug in.. then restart.
yes timing moves as per ECM specs. check that timing did no get out one tooth when you replaced distributor. retime . restart

If you had a bunch of cracks in your distributor cap it may have caused the pick up coil under the distributor cap to go bad and cause this problem.

You said the problem happened right after the engine was replaced correct? If so bring number cylinder to top dead center on the compression stroke. Remove the distributor cap and see if the rotor is lined up with the number one spark plug wire. It's possible the distributor was installed 180 degrees out.

so spark either points to the PCM or the crank sensor. Providing you have checked fuses and if you havea ECM or IGN fuse and they check out good.

Every time it rains my van wont start. next day its ok. what could i do to fix? its a 1993 gmc rally g-3500 van


check the ignition coil for spark or cracking noise there might be a crack in the casing .....do the same for the distributor cap. If you cant seem to see the problem take a water bottle and spray around your engine whiles its in idle and listen to see if the engine sounds different ....but only spray one part at a time.

I think you should check your timing again, check the firing order of the distributor and if they are with there corresponding spark plug. Did you mark the connector or label them before disassembling. Maybe u left the timing in exhaust instead of compression
