Unless you have run it out of oil a few times. replace the oil pressure sending unit. I am assuming you have an eight cylinder in the van, so the sending unit is on the back, top of the engine. About 3" long and 1 1/4 " in diameter

LOW FUEL PRESSURE WILL CAUSE THIS

because your oil pressure rises to around 40psi when running and will leak at the weakest place,check your oil sending unit first and seals.

Hi, I see you have changed a bunch of items, but do we know if the engine is getting fuel pressure? (55 psi at test port), or getting good spark? Could the spark plugs be fouled?I think before you replace too many items, you should start with basics. Good luck, Thanks...

My first guess would be the low side pressure switch, If you have checked all fuses?

look at both valve covers its got to be around there.thanks

very rear of engine center of block behind intake.

to test the ignition coil hook a meter to the respective ends. there should be infiinite resistance in ohms on the coil
