Got it. I unbolted and flipped the filter housing and the two wires going into the heater have the insulation pulled back about 1/4 inch and are definitely shorting. Thanks for your help, Grant.

Update: 20a “gauges” fuse blows when I turn the key. I have removed gauge cluster and unplugged ECM.

I was using my truck yesterday with no problem. I went poking around by the fuel filter looking for a fuel leak (didn’t find source). A while later I went to move the truck and the Speedo, tach, SES,...

Hi Grant,
Looks like my lift pump was on the way out prior to all the work I did including installing the secondary filter and new injectors. I found the bad injector… #3. Looks like it was leaking...

Thanks, Grant. I just replaced the LP so it looks like I need to just clean out the filter housing and replace the filter. I really hate the design, the fact that all the dirty fuel spills out of the...

Would metal flakes in the stock filter housing indicate an injection pump on the way out? They seem mildly magnetic. I have a secondary spin-on filter between stock and IP so I’m not terribly worried...

Thanks for the info, Grant. I don't have an erratic speedo, the only indication that I do have, other than the code, is the occasional hesitation or the engine will rev like the trans down shifted....

Grant, thanks for getting back to me, sorry for the delay in reply...
I see what you're talking about with the internal solenoid connector. On the same side there is two (visually identical)...

Quick question, I have 2 vehicle speed sensors on the side of my 4l80e trans but only the front is plugged in. I've done some reading and it looks like the 4wd trucks may use a (third?) speed sensor...

Ok, thanks Grant. I'll keep an eye on it.

So this is what I know at this point... The volt gauge hasn't worked in the 11 or so years that I have owned the truck. In that time I have replaced both the alternator and the ignition switch so, my...

10-4 on the speed sensor. I’m taking the truck to a trans shop to get it the once over anyway but I’ll keep that in mind.

Are you saying that the instrument cluster is likely the culprit on the...

Speedo seemed to work ok but was a little bouncy. Sub sat for almost 4 years before I tore it apart this spring. It did run but I didn't want to push it, knowing it had an issue with the one exhaust...

Took Sub for a drive and it seems that the trans reset and I have all 4 gears... for now.

Thanks for the reminder that although the SES light won't necessarily light, sometimes a code is stored....

Finally got it running about 6 weeks ago, then left town for about a month. Here's what it took:
I replaced the new lifters and had no change. So after some deep contemplation and rethinking some of...

Huh. ‘95s have a cable that runs through the cab. Wouldn’t have guessed. Any thoughts why they did that? Sorry to hear about the HOA. MinE is still sitting in the street, fortunately my neighbors are...

No cable, its all linkage to trans. You may be able to disconnect linkage to see if it is in fact in the trans or steering column.

I saw no “smoking gun” that would keep the lifters from adjusting, although the piston inside was a little difficult to get out of a couple of them. The only thing I can think is that either when...

I have finally gotten around to pulling one head (drivers side) and all the lifters. (I’ll do the other one later.) I was only able to compress two slightly by hand. The other 8 were rock solid. When...

Never worked on ‘60s Chev, that sounds like a messy job, yikes! I think you’re right with pulling a lifter. I’m going to wait until it cools off a bit we’re pushing 110. I’ll let you know what I find...

Ill give it a shot. One more thing, I cranked the motor over for about 25-30 seconds, without the valve covers on. By the time I had pressure at the gauge I only had oil coming out one rocker, the...

I’m looking at .923 and I didn’t see anything funky when I put the new ones in. I have to admit I didn’t even think to look if they were different sizes. If mine are standard is there an undersized?

I kept one lifter and I have a mic (but its in inches) what measurement are we looking at?

Thanks Grant. I’ve been in contact with Walt. He’s been really helpful. I’ll let you know what I find out. All indications point to the lifters not compressing enough to allow the valves to close.
...

It’s a worthwhile question... yes I did.

I’ve been thinking about it a lot and what has changed during rebuild, considering it did run before I pulled it apart. Only thing I can think is that I...
