Heard a pop when I started it, now no blower or blinkers
When I went to start i heard a pop from outside. There was a small puff of smoke from under the hood that exited at the back of the hood right in front of the driver and another puff of smoke came out of the steering colum near the ignition switch. Now I have no heater blower motor or blinkers and my airbag light is on.

Doesn't sound good Al. Check your engine oil level and make sure it is ok. Could have had a rod bearing seize and fubar the whole engine. Oil puddle under van? Squeaking related but without hearing noise is a tough one. I have heard engines that are on the verge of seizing up to squeak as the bearings seize up and then finally just freeze and seize together. On a lighter note the vans are also prone to having the PCV hose at the back of the intake manifold fall apart and deteriorate. Odd noises have emanated from this sometimes very large vacuum leak that is created. Squeaks, Whistles, etc. If oil was in the hose at time of rupture then oil would have dumped onto the rear exhaust manifold that may have created this smoke from under the hood. You can find more information on this hose at mpvclub. If the engine still cranks over normally but will not start or starts and dies then can rule out the engine damage. The squeaks from this problem are a death call and engine will just not turn over at all.
I would say you need to take your cat off and check to see if the monolith is blocked/broken up. The big puff and black smoke tell me you are getting a pressure build up, a blocked/broken up cat is the most likely cause of that.
blew the piston rod through the oil pan if you have bad luck. if your lucky the oil filter blew off and wont start because oil is low. look under car for where oil is coming from. if there is a piece of metal hanging out the hole your engine is toast
The reason for the smoke under the hood is called a lean misfire,not enough fuel entered into the combustion chamber,what you heard is a cough.This may have blew off the air duct tube for the MAF (mass air flow).So the vehicle wont start,The maf sensor could be the reason for the no start it could be faulty,or just a fuel pump going out and not producing enough fuel pressure,so if anything your solution is a fuel pump with a fuel filter
Sounds like one of the accessory pulleys locked up and smoked the serpentine belt. The air conditioning pump would be my first suspect, but grab all the pulleys and turn them. The problem pulley will probably be discolored, and have belt residue on or near it.
Hate to say it but you have to start tracking wires... Start from your battery and go from there. Sounds like a possible fusable link that blew but the only way to tell is checking for power from battery cables. keep me informed.
