Sooo... what is your recommendation for an IP...?

Will, ak diesel driver.... I dumped cold water on the IP... .while it was hot and would not start. It started. Now.... is that water supposed to cool off the PMD or the IP?

Okay... More symptoms.. thought I had found the problem a couple of times but it is still being hard to start. >#1. Starts like a gas engine in the morning when cold... very prompt response to the starter.. starts right up! >#2. After it warms up to right at 205*, it is hard to start. The...

The Fuel Filter Manager is going to be next... I've already decided that. I see there is an excellent explanation and photos in the Technical Reference Library. That is going to be a very handy reference. I am not sure about mine. When I went to get a filter for it, I could not find one to fit...

Step 3 Get the air out! (This is actually step 1 in the GM manual.) Air leaks will cause starting problems because air compresses and no fuel gets delivered. Put a 1/4" clear return line on IP and watch for air bubbles. Primed the system and you are NOT ready to go the next morning if you have...

Yeah... I read all that stuff in the technical reference section. Then I posted my question that was not addressed in the technical reference section and continued to research on line and found the info that I needed for a 1995. if you had the answer you could have saved me a lot of time and...

For all you '95 6.5 Sierra owners out there... this is what I have found so far. The lead goint to the "Fuel Pump Prime Connector" is goint to the Data Link Connetor under the dash (F). The pump does not run until the switch is in the "crank" position. Then the OPS (Oil Pressure Sensing) switch...

In the schematic for a 1995 6.5 Sierra K1500, there is a wire coming from the Fuel Pump Relay to the "Fuel Pump Prime Connector". I am assuming that this wire is the wire that energizes the LP when the switch is placed in "Run". Where is the "Fuel Pump Prime Connector"? The problem is: the pump...

Okay then. Question... What makes some turbos whine (spool up?) and others not? I can hear my Suburban's turbo when in heavy traffic or alongside a fence or other barrier... the Sierra I cannot hear at all. I notice in looking at turbos on line that there is a difference in the 1995 and the...

As far as the '91 Dodge Cummins 5.9 that I own... I had that injector pump all apart and I did not see no "aneroid". I saw a diaphram acting on a fuel pin.

Yea.. you're right. I did miss the point... I stand corrected. I thought they were just showing off how fast their truck was... Explains why no one else pointed it out.. lol

I thought that relay on the firewall was part of the egr system... The MAP sensor is in the output of the turbo. On the dodge, there is a diaphram that feels the boost pressure that moves the fueling pin down and up to give more or less fuel delivery. When the Sierra goes "pooot-poot-poo", the...

Not sure what has happened but the '95 Sierra turbo started working as it should or at least how I think it should. It may well have been a carboned up waste gate valve/seat... It holds a steady 3.5 lbs at 70mph and increases any time I accelerate... It still does that "pooot-poot-poo" when I...

I get good milage with the Suburban... It is not 4.10... it is higher than that as I crawled under there and checked it when I bought it. It was a 3. something... probably 3.73. The Sierra is turning about 2100rpm at 70. I bought a wore out work truck for my brother (1996 6.5 t/c) and it had a...

OK.. Let me think about that a while... didn't know that was happening... (I remember now; the TC locks up at about 52mph) I did hit the brake while going 55 and the RPM did change..... I guess that is why the engine slows down a little when I hit the brake. What I am thinking is that the drag...
