mounted new starter . went to reconnect battery, touched red to terminal and the van cranked without key in! What is wrong? Is ECU involved?

checked obvious stuff like fuses.
im thinking that the odometer is responding to the speedometer.
should i start my search for the cause at the speed sensor or some place else?

Excluding obviously poor quality mfg, like China, there is still a range from Delphi at at$70 to Ac Delco at $300. What is the reason for this. Im i getting more if I pay more?Last week I got a new fuel pump assembly priced at $280 locally, for $48 on line. It was perfect. I understan the brick and mortat mark up but that does not address why the vast price range on line. Am I missing something here?

Question 2. as long as I am at it should I change out plugs and wires as well?

a cracked distributor housing makes me want to replace it. what do you think?

I did a scan for my check engine light and it says cylinder 3 is misfiring

I start the engine, doors lock, but while I'm driving down the road the door locks click like they're trying to lock aagain.Also, when I shut off my vehicle the radio automatically shuts off instead of playing for 20 minutes or a door is opened. I'm trying to think of what might be wrong.

Can anybody help with brake line routing to help me find & repair a leak? Seems that leak is somewhere around the front frame crossmember - Thanks

The van was electrically dead after driving it a half hour before. When we tried to jump it, it almost caused my buddy's truck to die and over heated the jumper cables. Took out the old battery and when installing the new one it arced and caught the side post on fire. What would cause this kind of short?

Doors do not lock when the engine is off but lock normally when engine on and transmission put in in drive. When trans back in park, doors remain locked. It unlocks when engine switched off. Off function of locks is corect and work fine any time.
