Question about 1998 GMC Yukon

3 Answers

Have a 98 yukon hard starting

Have a 98 yukon and starting it has been getting more and more difficult.. Seemed like when I cycled the ignition several times it would start.. But now I just hear the pump whining for several seconds on both sides of turning the ignition.. Finally won't start at all now.. I poured gas down the carb and it fires right up.. runs fine once I get it started.. Feels like the bleed off drains all the fuel out of the line.. Is that a regulator issue? Thanks in advance everyone..

THIS IS A EVER SO COMMON PROBLEM ON THESE VEHICLES. THE FUEL PUMP HAS A BUILT IN CHECK VALVE WHICH IS SUPPOSED TO PREVENT THE FUEL FROM RETURNING TO TANK AFTER SITTING. WHEN THE FUEL RETURNS TO TANKYOU WILL EXPERIENCE AN EXTENDED CRANK TIME. THE PUMP COMES AS A COMPLETE UNIT ON THIS MODEL AND IS FAIRLY EXPENSIVE(250.00 OR SO) HOPE THIS HELPS AND DONT FORGET TO REPLACE INLINE FUEL FILTER AS WELL!!

I HAVE A 98 GMC YUKON THAT HAS A COLD START PROBLEM. fIRST START OF THE DAY AFTER THAT RUNS FINE. AND SUGGESTIONS?


sounds to me like your starter isn't shimmed correctly common problem for the 5.0l and 5.7l. your starter isn't meshing with your fly wheel correctly and causing unnecessary strain cause the problems you stated.

98 pontiac bonneville-ignition not engaging


There are a few components that could cause the problem. Bearing in mind the hard turn issue last week, I would first suspect the manual ignition switch, which is located on top of the steering column under the dash( not the key switch). All other components would not affect the hard turning issue, other than a dry ignition lock cylinder, so that's why I would first check out that mechanical switch.
I don't know your level of aptitude or what tools you have, but this is not a very difficult fix - but it will take time.
If you would like to fix this yourself, let me know and I will be happy to help walk you through the procedure.
Hope this helps!!

On my 96 yukon the air won't get cold its not


if it WAS working then gradually just seemed to not get cold it sounds like freon is low. with the compressor cycling on-off it has some freon in it. just add a small amount. i'll be honest its best to have someone with the recycler machine do this it will save you from adding too much and possibly damaging the compressor. most shops have a freon service special around 99 bucks?

I need to know how to program my universal keyless remote control to my gmc yukon


This is the procedure to reprogram your remote:

Press and hold the drivers side UNLOCK button.

Insert the key into the ignition, Turn ON, OFF. (do not start)

Repeat 2X. (3 times total)

Locks should cycle to indicate program mode.

Press and hold LOCK and UNLOCK on the Remote to be programmed. (may take up to 30 seconds)

Locks should cycle to indicate successful programming.

Ignition ON to exit program mode.


If it still doesn't work after this you probably have a bad remote. Hope this helps.

My 2005 Yukon denali won't start, I have replaced the fuses, relays, the starter, the ignition switch, battery, and removed the alternator and had it checked. The truck still will not start without me...


My guess would be the anti theft security system. When this system starts to fail, it turns off the starter from the ignition. The fact that you can hard start it proves this. Read this link for symptoms, info, pictures, and solutions to this problem. http://vatspasslockpasskeysecurityhelp.yolasite.com/

Getting hard to start.....have to hit the ignition switch at least twice for it to start


You turn the key and nothing happens?

The engine turns over normally but takes longer to start?

The later is either a fuel pressure regulator or a bad fuel pump. If your fuel injectors are on the outside of the intake plenum (you didn't specify the motor) your in luck. If you look on the drivers side of the fuel rail you will see the fuel pressure regulator. It will be a round metal part with a vacuum hose going to it. Pull off the hose and see if gas comes out of the regulator. If it does it is bad and needs to be replaced.

If you have Central Port Injection or the fuel system is inside the intake plenum. It will be a little more difficult to confirm a bad regulator but I wouldn't hesitate to replace it as a good starting point. With the upper plenum removed you will still be able to cycle the key to the run position and see if the regulator leaks out its nipple.

2000 contour


for 98 contour issue. TSB 98-21-14 not covered by warranty

This TSB article is being republished in its entirety to include the 1999 Cougar . ISSUE: The ignition key may be difficult to insert or remove and/or key chimes may sound with the ignition key removed and driver's door open on some vehicles. This may be caused by internal design characteristics in the ignition lock cylinder increasing insertion/removal efforts which may allow the lock cylinder to stick.
ACTION: Install a revised ignition lock cylinder. The revised ignition lock cylinder should reduce the possibility of high insertion/removal efforts and ensure proper chime function. Refer to the following Service Procedure for details.
SERVICE PROCEDURE
  1. Verify customer concern.
  2. Observe the ignition lock cylinder as the key is removed. If the lock cylinder snaps outward to the non-depressed position and the chimes stop sounding, continue to Step 3. If it does not snap outward, replace the ignition lock cylinder with the appropriate cylinder by referring to the Parts Block in this article.
  3. Insert and remove the ignition key from the lock cylinder. If binding or high efforts are encountered, replace the ignition lock cylinder.
  4. From the Parts Block, select a lock cylinder with a part number suffix identical to the center character of the key code of the vehicle. The suffix must match the center key code character to maintain a single key system.
  5. Install the replacement lock cylinder, by referring to the 1998 Contour/Mystique Workshop Manual, Section 211-05 or the 1999 Cougar Workshop Manual, Section 211-04. NOTE: KEYS INCLUDED WITH NEW IGNITION LOCK CYLINDERS ARE CUT FOR THE IGNITION ONLY. IN ORDER FOR THE KEYS TO FUNCTION IN THE DOOR LOCKS, THE KEYS MUST BE CUT TO THE DOOR CODE OF THE ORIGINAL LOCKSET. THE KEY CODE WILL CHANGE UPON INSTALLATION OF THE REPLACEMENT LOCK CYLINDER (FIGURE 1).

    tw2114~us~en~file=tb5525a.gif~gen~ref.gif
    Figure 1 - Article 98-21-14

    NOTE: ADVISE THE CUSTOMER TO DISCARD ALL KEYS THAT WERE CUT TO THE ORIGINAL IGNITION LOCK CYLINDER.
  6. Record the new key code on the repair order and provide to the customer. Advise the customer to record the new key code in a permanent location and to discard all references to the original key code. NOTE: REPLACEMENT IGNITION LOCK CYLINDERS ARE SHIPPED WITH NON-PASSIVE ANTI-THEFT SYSTEM (PATS) KEYS. IF THE VEHICLE IS EQUIPPED WITH PATS, OBTAIN TWO (2) ROTUNDA KEY BLANKS (OR OTHER FORD AUTHORIZED BLANKS, SUCH AS: ILCO, STRATTEC, CURTIS, HUF, OR VALEO) AND CUT TO THE REVISED KEY CODE. USE OF OTHER UNAUTHORIZED KEYS MAY CAUSE ERRATIC OPERATION OF THE PATS SYSTEM.
  7. Program PATS keys using one of the two following methods:
(1) For vehicles with Integrated PATS (IPATS), function built into the Powertrain Control Module (PCM) and built beginning:
  • 2/2/98 Kansas City (Contour/Mystique)
  • 2/16/98 Mexico (Contour/Mystique)
  • All 1999 Cougars
Using the New Generation Star (NGS) Tester equipped with Service card (green) level 3.0 or higher:
  1. From NGS menu, select:
    • Service Bay Functions
    • PCM
    • Enter Security Access (10 minute delay)
    • Ignition Key-Code-Erase
  2. Disconnect Data Link Connector (DLC).
  3. Cycle the first non-programmed key in the ignition to run position for at least 3 seconds and then turn to the off position.
  4. Cycle the second non-programmed key in the ignition to run position. The theft indicator should prove out for 3 seconds.
  5. Verify the vehicle will now start using both keys.
(2) For Contours/Mystiques with Stand Alone PATS and built before:
  • 2/2/98 Kansas City
  • 2/16/98 Mexico
Using the New Generation Star (NGS) Tester equipped with Service card (green) level 1.0 or higher:
  1. From NGS menu, select:
    • Service Bay Functions
    • PATS
    • Ignition Key-Code-Erase (this process may take up to 8 minutes to complete )
  2. Disconnect DLC.
  3. Cycle first unprogrammed key in the ignition to run position. First key will program and allow vehicle to start.
  4. Again cycle first programmed key to run position. Within 15 seconds, remove original key and turn new unprogrammed key to run position. The theft indicator should prove out for 2 seconds. New key will start vehicle.
  5. Repeat this process for additional key programming. NOTE: THE FOLLOWING SHOULD BE NOTED FOR THE PART NUMBER BLOCK:
    • Part Number suffix will match center character in key code
    • Logo on key is Ford for Contour models
    • Logo on key is Mercury for Mystique and Cougar models


PART NUMBER PART NAME F5RZ-11582-A Ignition Lock Cylinder (Contour) F5RZ-11582-B Ignition Lock Cylinder (Contour) F5RZ-11582-C Ignition Lock Cylinder (Contour) F5RZ-11582-D Ignition Lock Cylinder (Contour) F5RZ-11582-E Ignition Lock Cylinder (Contour) F5RY-11582-A Ignition Lock Cylinder (Mystique, Cougar) F5RY-11582-B Ignition Lock Cylinder (Mystique, Cougar) F5RY-11582-C Ignition Lock Cylinder (Mystique, Cougar) F5RY-11582-D Ignition Lock Cylinder (Mystique, Cougar) F5RY-11582-E Ignition Lock Cylinder (Mystique, Cougar)
