Hey guys, im havin big time problems with my truck and wondering if you guys can help.

Alright i have 94 Dodge Ram 1500 4x2 5.9ltr truck.

and here's the problem..

Well i changed the oil on my truck, then i went to start the truck and oil pressure gauge was readin a bit low (25psi) at idle, and i was like hmmm??? seemed really low, then i look

at the sensor and it looked a bit rough so i replaced it, well i read evn lower... 20 psi, so i said **** it, and replaced the oil pump, oil pick up, oil pickup screen. and started it up

and it read 40psi at idle, and i was like "YES" ive got it fixed . but then i drive it 10 feet and the pressure drops to 15 psi... then the oil light itself lights up, and then my temp

gauge spikes to 210 degrees. I then looked to make sure everything was nice in tight, and it was.

Oil im using 10w-30 Castrol GTX

Filter im using Dodge OE Filter.

please help quick!! I need this truck bad next week to tow my race car!
