SO after charging both batteries overnight I loosened all the GPs and cranked until they ALL bled. Tightened them down and on the second crank they lit off. During the test drive it was slow to develop speed- the trans sounded like it was whining for a shift; second gear came late-sounding at...

UPDATE: I'm not closing out the thread yet, but I am making progress. I installed the 60G plugs- I have been running them since my first change from stock Wellman's. The GPs were purchased at a price more inline with MSRP- Bought from the ACDELCO seller (really ACDELCO?) on Amazon. They went...

:oops: Sorry for not giving any context here. Yes, I meant burning exhaust.

Pink wire secure- CLICKs with juice applied. Could all the GPs be bad? They are not old but I got them at far too great a discount on theBay- I worry that they might have been counterfeit 60G :cautious:. The batteries are holding up- they crank well but all I get is a burning smell and a...

Chasing down my NO Power above 35mph, I installed fresh Fuel injectors. Went pretty well. The problem is it cranks, no start. The batteries are strong, and there is fuel getting to the injectors- I cracked the inlet connectors at each injector. The engine was running with immediate start up...

Looks like I'll drop my tank and see if the sending "sock" filter is to blame for my loss f power. As I was readin the forum on sending unit replacements I found https://www.steelsoldiers.com/attachments/img_3721-jpg.301195/ But I found the following in the 34P TM: 3PAOZZ 11862 [Part...

I have read several articles about transmissions that give out and render a maximum speed of 35MPH- to "Limp Home". The issue seems to be a shift solenoid.. Is this a thing with the 400?

I forgot to adjust the shift points via the VRV 🙄. So, I think I messed up something because I have rotated the VRV fully towards the rear of the vehicle and I cannot bring my 1st to 2nd gear to shift any sooner than 24MPH. 3rd never comes in until over 35mph. Not sure, but I feel like my...

Thanks for the visual, cucvrus. I'm sure you are right on this, but like everyone else, I wanted to follow the path of least resistance before dropping the tank. I filled it up the morning the Blazer presented with this problem. I'm about out of remedies to try so it looks like its time to drain...

This morning I checked the vacuum Pump- I got a median read of 20 Hg with the needle bouncing wildly between 16 and 22. The fuel pressure is pretty steady at 8Lbs. I removed the metering valve from the injector pump- more work than I needed to do in retrospect. It was a little funky- only a year...

Changed the Fuel filter, and checked all fuel lines for leaks or damage. Nothing changed. Starts at a crawl eventually gets to 35-40. How can I rule out the transmission? Reinstalled the fuel pressure gauge after the filter- holds fairly steady at 8lbs.

The filter is a couple of months old. I did fill the tank yesterday at $2/gallon. I wonder if the diesel was bad. Hmmm :unsure:

Yes, about a year and a half ago. New injectors and glow plugs as well.

On my way fishing- never happen when I'm on my way to get a root canal, and the pedal feels off as the engine starts bogging. I can keep the Blazer moving t get off the highway, but only just. Visual inspection turns up nothing. I limp back into town, find a diesel shop, but they can only guess...

Changed the Transmission Fluid/Filter/Gasket. Went pretty smooth, but hoped it would cure the low power the '09 was having- even low hills quickly reduce my speed to 45 MAX MPH. I thought maybe clogged filter or leaky trans filter tube. NOPE. I'm changing the spin on to an AC Delco base. The...

The last two pumps I installed (Delphi) went in just as the others I've replaced in Chevys and Fords over the years. The last two, though slipped around on the end of the crack rod. It was up as far as it would go- held in place after freezing the rod and adding a dose of heavy grease to it...

cucvrus, thanks again- from your previous posts on correct lift pumps, I chose as I posted above. I do understand that the lever should be pumping from any pressure applied, but I wasn't able to depress the lever by hand- even a little so I couldn't be sure. The j-code Delphi p/n I gave, does it...

cucvrus: Fuel Lift Pump-VIN: J, DIESEL, FI AUTOZONE/DELPHI CHFP906 (THEEbay) is the one I installed. As I recall the spring is on TOP at the rearmost of the lever deep in the housing. Is this the correct one? I offer thanks for all responses so far. I want to be sure I have the correct pump...

I bought mine at Sherwin Williams- not a retail store. I went to the industrial SW supply. I took a Purchase Order with the Type II number on it and the reducer number. They entered it, asked me if I had an account. I said "no, I'll pay cash." In and out in ten minutes.

Over the last week I noticed a lack of power over 35-40 MPH. I can get more speed, but very slowly have to work up to it. If I get on the freeway and try to maintain 60ish, I get vibration and shutter. I've read as many posts as I could find here and have already changed out the spin-on fuel...
