When this happens, have you checked to see if the engine is getting spark and fuel?

It tries to start runs for 3 seconds then dies maybe long enough for about 20 psi oil as I have no tac if it sits for hour it will run I drove it all day 2 day and it never did it may go for weeks before it does it again guy told me grounds engine frame going to try it as gauges are going hay wire also dash has every light that could ever light up on and head lights flash like when you signal someone for cops doing radar crazy f---ing van my friend who owns a garage has never heard of this before this van is a real gem also you can hear fuel pump runing to check for spark and fule is a ball bust bacause of cowl maybe I will run it with out for a couple of days thanks

It does sound like there is a ground problem. Have you checked the ground from the battery to the engine block?
