This thread has been sitting open and time to close it. This started due extended cranking from a leaking fuel filter. Fixed that but I didn't realize the CCA and reserve capacity was now too low to start it. Worse and the real problem in the end was the battery acid used to service the...

It 62 pages which is the full manual for rebuild. It seems you always reference "other people" with no link to proof anything you are saying is true. On this site Leroy Diesel has posted several times 13-15 psi your engine will thank you for it. 15 psi does not "stress" anything, and in...

I am perplexed why you are stuck on the 8-14 psi operating range spec to insist anything else is wrong. You say some engineer told you that. That without proof, is called "hearsay" But then other authority sources and fact contradict you. For one the DS4 test spec is 5 psi + or - 1%...

Ah yes, "made in the USA" likely always meant "assembled in the USA". The plastic case, the die cast frame and even the circuit board is likely made elsewhere imported and final assembly done here. It is a big investment to make all of that here. But flightsystems does not own the PMD...

Ah yes I am familiar with the Stanadyne shop pitch. The shop is not allowed to give information which does not match the GM spec, for example the EP158 PUMP spec is 9.5 to 14 so that is what you tell the customer. The shop was not, as a stanadyne repair and rebuild shop, not allowed to...

Simply do not use a diaphragm regulator design that can crack or tear the diaphragm and fail. Use a pressure plate design that is two discs against one another by spring pressure. The discs must fail or the spring loose all temper. Mine has been working for over ten years Don't use a pump...

GM did not design the PMD Stanadyne did to integrate the rehostat accelerator pedal into the gm ecm and for automatic start functions to control the Stanadyne DS4 IP. One company popped up with an extreme heavy duty PMD for $350. They disappeared almost instantly. The issue is simple...

The transistors cost too much now. https://www.amazon.com/MJ15004G-Complementary-Silicon-Power-Transistors/dp/B082S34GBK I use this kind of iron. https://www.amazon.com/RadioShack-45-Watt-Desoldering-Iron/dp/B007Z7MNEM I used a harborfreight.com El cheapo dremel style tool kit...

Nope. The fuel shutoff solenoid arrived Sunday, but before I tackle that - on a Van a major job - I am going to try a new PMD. I normally keep a spare new one or working repaired spare, but the last time I ordered transistors they all arrived testing bad except two from yes, China. I...

On the subject tangentially, a parasitic draw was found by way of direct short and small fire. With the hot charger starter hooked up the volt / ammeter gauge caught fire behind the dash. It could be seen through the plastic dash. A quick unsnap and a puff blew out the fire. It appears for...

All DS4 is are the same but as I said the issue is It is a job to get to, as it is under the air intake heading to the turbo I just hope I will be able to swap it without taking out the doghouse

I am thinking it is the fuel shutoff solenoid. It takes 13.4 volts - plus those amps of either 50 or 200 in in charge or start mode and it fires right up. The solenoid is likely too weak to open on 12.5 volts. So of course I need to order one I just hope it doesn't crap out on me driving...

@dbrannon79 the new starter spins it plenty fast. @MrMarty51 no, the batteries are on the side in a case with a door, but since it fires right up on the starter / charger, I must have an amperage problem maybe a ground or the batteries need servicing. I have a foxwell bt-100 tester, so I...

Spent 11/23/2024 swapping the new starter back in. Spins the motor but won't start UNLESS the starter charger is hooked up in start mode. It will start it cold or hot but even though the batteries are fully charged and crank the engine fast, it only starts INSTANTLY with the starter charger...

Those parts and yokes are not there. Nor is the front input shaft. Nor the front shaft carrier. It was looked into machining the parts needed. If someone there wants one, there is one on ebay right now for $399 as itm/ 375778843624 So let's put that to bed, it is cheaper than I would put...

It is a laycock not a gear vendors. See https://www.maximum-overdrive.com/ for how it was to be used to replace the middle drives haft. Anyone can set ebay to notify a keyword post

You don't need to tell me. The fear that washed over me when I saw the heat shield hanging to me meant that chunk of the block was torn out where it screws in. After getting the starter out I found all was well with the bolt hole and threads and the flex plate. I put the old Delco Remy...

Not going to do that. "Never sell a used car to a friend". It is not bolt on ready, and needs adapters made

Costs money to store stuff. It is a 74 G30 where the chrome wheels are probably more valuable than anything else but the built 700r4. The reminds me I have a laycock (gear vendors type) overdrive I need to ebay away
