Hey Ed, not that I can see anywhere.  There's a different kind of numbering scheme that you can search for though.

NATP9442 - 1994 C/K Truck Driveability, Emissions, and Electrical Diagnosis Manual
NATP9431 - 1994 C/K Truck Service Manual
NATP9437 - 1994 Light Duty Truck Unit Repair Manual (also contains some non-GMT400 info)

I believe there's also a "Diesel Supplement" that goes more in-depth on the 6.5td but I don't have it.

The three books I listed are the typical set of manuals, at least for 1994.  Over the years, what comprises a set seems to change up a little bit.

In doing a little searching apparently there's also:

NATP9432 - 1994 Chevrolet/GMC P3 & P/G Chassis Service Manual
and the diesel supplement -
NATP94DIESEL - 1994 GMC C/K, G, P3 Truck Shop Diesel Supplement

Thank Ed.
I sent you an email a few weeks ago.

I will get you that serial number, I am just looking to maximize what is there, nothing really special.

I had a bad pickup coil, I chased that problem for 2 weeks and a few hundred dollars, but its figured out now. I new the knock sensor was not hooked up, when I bought it, it ran good, so I didnt fix it, I found out that the SES lights was blown, i fixed that, now I find out it has been trowing a code for the knock, I have ordered one and a pig tail for it, should be here tomorrow.
I have the high pressure fuel pump and sock, I am installing this weekend. I also found the sway bar links for 3$ discontinued on rock auto I needed the bushings. I have shocks,bushings, links ordered as well.

I live an hour from the area hit by Hurricane Michael, I have a load of supplies and my tractor heading out next week, just trying to iron out a few bugs before I go.

Which ecm is the truck using, does it have a removable prom or is it soldered in? For example the 1227747 ecm has soldered in proms that can be un-soldered and replaced with a ZIF socket.  Then you can flash an eprom and insert it in the zif socket.

Been a while but I have converted 747 ecm's in the past with zif sockets and can burn the eprom...but need to know how you want it burned.  Suggest that you join this forum and seek their guidance as how to alter (tune) the bin.

In the meantime can you look at the ecm and give me the Service Number and the four letter bin Code?

You need get the knock sensor figured out, make sure you have a 454 specific knock sensor.

Hey, does anyone here burn chips for the TBI ODB1 engines?
I would rather not buy a hypertech or jet unless that was a better option.


My 454 gas is stock with a turbo 400 with overdrive. I am looking to override the B.S. sensors and maximize the HP and Torque, from what is already there. I have just replaced and upgraded the whole ignition system chasing a bug, turned out to be the coil pickup under the button/rotor. It is running better than ever, but now it throws a knock sensor code.

so if anyone makes these let me know,
thanks
MrC.

I took a 50 m.p.h. tumble in a freeway crash on my Ultra Limited in '14;  broken left hip, broken left wrist, damage to all 3 zones of my back, TBI.  I can muster good wrenching sessions in a heated shop, but alas, I fear my days of heavy work are gone.  I'm bailing from the 1 1/4 ton platform for a restoration project, I have other plans for my low mileage 8100 Vortec and Allison 5 speed.

The 3500HD is solid, I found it in the Nebraska plains last year.  The 6.5TD isn't running and the wiring is a bit cut up, it does crank.  I can take more images to post and send.

Call or text 248-893-9220, no listings elsewhere yet.  Please leave voicemail if I don't pick up, cell service is poor and slow here in the boonies.

The factory manual set includes info on all models including the HD.  My 1994 C/K truck manual set does, anyway.  These can be a bit pricey to buy new from Helm; sometimes you can find used sets on ebay - still pricey.  Try to stick to your year model as powertrain and harness differences vary quite a bit depending on year.

Yeah. it seems to just be part of the frame. I'm gonna pull the old one and see if it can be repaired. I have some feelers out to junkyards but we shall see. Napa was the only place that had brakes for it.
