2001 GMC Denali - Page 6 - Answered Questions & Fixed issues

What year is your vehicle,motor size and what model do you have and I will be able to help you.

I think that the best solution will be to get the manual for the vehicle as the diagram may be included there and not online for some reason.

I looked on Autozone.com and on my online resource which is based on Chilton and Haynes but bodywork information was not listed.

I wish you luck on finding information on how to put the nose of a 1999 Yukon, Denali together.

Something is obstructing the sensor

Ck your fuses

possibly 4 things 1 bad ignition coil heating up then breaking down,2 clogged fuel filter,3 weak fuel pump,4 bad throttle position sensor or map sensor to check sensors simply put on hand held scanner and look for codes. replace fuel filter replace coil pack along with tune up plugs wires put fuel pressure gauge to see if fuel pump is working properly

have you changed the tires

You should check the fuses. sometimes the rear doors are on a different fuse than front. could also be a break in the wire where it passes through one of the rear doors.

It is located along side of the driver's side frame rail, almost directly under the rear seat. Hope this helps!

With a single serpentine belt most gm models have a belt tensioner which has a small square hole in the tensioner. You put a 3/8 inch drive ratchet in the hole and pull up or push down to release the tension off the belt. Once you have released the tension pull belt off of one pulley and you can ease up on ratchet and take ratchet out.

TRY THIS INSTRUCTION..GUIDE.

Need to know what model and year. Off the top of my head it is a fuel pump or filter.

it holds 6.0 qts if you change filter to, also there should be a reset button for the tire pressure in the fuse box on the driver side of the dash.

need to know what code is in it you must have it scanned

the teeth are broken off the starter replace your starter

that usually means you have a bad sensor (such as an O2) and the engine is running on self preservation mode. Take it in and have the codes pulled to see what sensor may have failed.

Try the ignition coil or the timing belt is loose or broken.

THE HEATER AND BLOWER RELAY. IS LOCATED ON THE BLOWER MOTOR HOUSING IN THE PASSENGER COMPARTMENT.ON 1999 THROUGH 2002 MODELS. AND IN THE FUSE RELAY CENTER IN THE ENGINE COMPARTMENT.ON 2003 AND LATER MODELS THE HVAC FUSE IS LOCATED IN THE FUSE RELAY PANEL UNDER THE LEFT SIDE OF THE DASH.

The control may have gone bad... You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. Then you can disconnect the controls and test them

Your fuel filter is located under the RH frame rail and it shouldn't be to hard to replace. You might wanna check your fuel pump pressure too.
