98 D1 for $700 out of a scrap yard. 65k on the clock. Didn't run and half the buttons worked. Working on a gravel driveway just long enough to get it to run and make a one hour trek with open headers to my work. There, I started fixing all the important stuff. 2 weeks later I totaled my daily...

The transmission in my D1 is about to pack it's bags and head south. I'll be tearing it open soon. I'll do a write up.

As I understand it, it's starting to start, boggs down with the first compression stroke and then keeps going. Only happening on the first start of a cool morning.

Only happening during cold, I'd start with a fresh battery. Then with a fresh battery I'd measure how much amperage your starter is drawing while cranking.

How old is your battery?

I used a moog 617.

If you use a decent volt meter you should be alright. My meter has a 500ma fuse. A .5amp draw will kill a battery over night. So you should be able to see anything that's killing your battery in a day or two without issue.

Use a volt meter and measure milliamps, that's the professional approach. Hook the meter up from the negative post to the negative terminal with the negative terminal still connected. Shut all your doors and lock the truck. Then disconnect the negative cable with your volt meter wired how I...

I personally would ditch the gasket, clean the surfaces really nice and apply a bead of high temp sealant that suits your liking.

And your pump is 100%? No wear on the faces/teeth and the thrust plate is flat? It shouldn't take that long to build pressure from a oil filter only removal.

The longest mine was lit was when the pump needed to prime, after having the pan and pick up tube off.

If the relief valve is closed the oil will only head south to the oil cooler port. If the relief valve is open, the oil will feed right back into the supply.

Take the cover off and look at it. I've had mine a part a few times. If the pressure relief valve is open, the pump will pump oil directly in to the oil port where the pump is pulling oil from. That's your exact description.

It's built into the housing right next to the pump. The relief doesn't intercept any certain line but opens up based on entire system pressure. So you can say it's before or after everything else in the system, it doesn't matter. It's designed to relieve system pressure based on a restriction...

You need to actually test the wiring to and from the ecm and knock sensor. You also need to check the ecm to make sure is not corroded, if it is, that needs to be tested as well. The ecm in your D1 likes to collect water. If all that checks out then you've got a mechanical issue somewhere. A...
