    Logan got a reaction from rockfangd in 95 Deville - AC ISSUES   
    Sudden no AC? Could be a bad compressor clutch coil. The pull in coil can sometimes fail and there will be no way to pull the clutch in. 
    Or....sometimes the air gap wears into excessive gap....and the coil can't pull the clutch in....or it only happens when the engine parts are hot and expand. 
    Both the AC coil and clutch plate can be swapped with the compressor in the car. No need to pull out the Freon. 
    Most AC shops will simply recommend a complete new AC compressor assembly. They make more money that way. 
    The actual style of the assemblies varies based on what brand of compressor etc you have....but the principal is the same. The brand can vary depending on year and engine etc. Some cars may have 2-3 different brands of compressors used on the same engine and year. 
    I had one go out recently on a non-GM product...of course it happened on the hottest day....taking daughter to airport in rush hour....just as we were getting on highway.. 
    Typically around $50 in parts.

    Curious.....Which cylinder do you think #2 is?
    Manual has you use Tech 2 misfire graph to verify. Manual has you move known good coil to replace....if problem still persists you replace the ECM.

    https://www.youtube.com/watch?v=Lt7GtMTfN3Y
     
    As for codes......the thing to understand is......there has to be code written to be able to see a problem. Sure it can detect a misfire.....but it cannot detect a bad PCM ground. 
    The scan tool not working is itself a clue. 
    Car may have no external fuel filter (in tank pad).......and no fuel return line..... 
    maybe high pressure direct injectors...but may be a little early for those..
    could be a cracked intake....etc
    Everything you know.....has changed.
    I would doubt what the little old lady said.....believe nothing of what you hear. She may have run it out of oil for example....you just don't know til you start inspecting the systems.
     
    UPDATE:
    Did look in the GM service manual. The 2006 SRX has...
    Inline fuel filter. It appears to still use a fuel return line. 
    Fuel pressure should be 55-65 psi @ idle. 
    There is .....a 15a fuse used for odd bank coils.....and a 15a fuse used for even bank coils.  Both fuses are in the underhood fuse block.

    The sheetmetal stays the same.....but the exterior and interior colors often change yearly. 
    Interior parts typically fall off the 'available' dealer parts pretty quick....a couple of years after production.....simply not enough warehouse space to store 3000 spare 2001 Eldo left slate A pillar trim panels.
    The aftermarket headliner colors are pretty generic.....maybe a couple of grays....a couple of tans....black.....etc. They will never match exactly unless you redo both A pillars and the headliner....and B and C pillars at the same time too. 
    In other words....you will never find a sheet of '154' slate.
    Some headliner material does have thinner foam backing material.....it's hard to find but it is out there.
    Best bet is to wait and just keep searching for the right parts car.

    I think adding to the problem is there are 2 very similar named solenoids. 
    There is a:
    EVAP purge solenoid. (Located under the hood) p0443.
    EVAP vent solenoid (Located on the evap cansister or on some other cars on the gas tank) p0449.
     
    The underhood ones (for me) seem to be more problematic than the gas tank ones. Have seen several cause a 'no code, no start after fill up issue'. Could get the issue to move to an identical car by swapping the evap purge sensor.

    GM service manual shows the threaded bolt style tool for the 02 Eldorado. Manual is not always correct....the other style was being introduced before 02....sometimes updates get overlooked.  
    That said....they also don't like to change manufacturing tooling toward the end of life of the vehicle.
    I did go look a wheel up on eBay....sure looks like threaded style to me.

    It could be nothing like a fuse.....or...it could be a serious network problem.
    Sounds kind of ominous and sounds like some critical details are missing.  Not something you normally see posted in car for sale ads. 
    It is not a normal known failure issue with those cars. (....Escalades are known for this if a penny gets in the cigarette lighter socket and blows the fuse...). 
    I personally would have a mechanic look at the issue and see if it can be quickly resolved. If not a quick and easy fix....I would walk away.

    Factory LED tail lights. 
    The third brake light can fail all by itself....so it may be unrelated. 
    Each tail light has its own fuse in the fuse block under the back seat. To add to the confusion....the fuses are not located side by side....they are spread apart pretty far in the fuse block. 
    Does the car have a aftermarket alarm system or remote start installed?

    Do you really mean crankshaft sensors? There are 2 on front of engine....kinda near the oil filter housing. 
    You do have the Northstar and not the 4.9L engine right?

    I have 3-4 DI cars here and have never had the carbon problem that I'm aware of.
    I guess we are offering ideas on what it could be. 
    Pretty sure you will need a scan tool to see any engine data....one of the parameters would show the fuel pressure. No way to hook up a gauge on a high pressure system. Pretty sure you will not find a fuel filter.

    You really need a scan tool that can display misfires. Most cheap scan tools will not. 
    Without being able to see which ones.....you are just guessing. 
    Attached is pic of a GM Tech 2 displaying the misfire graph. 
    Wifes Traverse just needed 2 coils on Sunday when she got home from out-of-town.....very clear to see on the Tech 2....2 cylinders with multiple misfires under load....one coil was noticeably worse than the other. To my surprise....took forever for the SES lamp to finally show a misfire code. (picture is old photo I have...not of the Traverse coils).

    Logan got a reaction from BodybyFisher in TPS and ICM Question   
    They are the same thing. The IAC is just a computer controlled vacuum leak. There are several different ones used over the years.  The rest of GM has been using these since the mid 80s. Only Cadillac was using the throttle control motor one. When OBDII came along Cadillac finally started using IACs.
    Has the intake ever been off? 
    Could be cracked or leaking intake or intake gasket. Or leaking blow off relief valve. 
    Bad gasket on either side of the "crossover" part.
    Leaking fuel injector O ring. 
    Broken return spring on throttle body shaft or sticking cable. 
     
    *The leak can be on the underside the intake....which you could never find by spraying around up top. 
    Spraying around.....keep the spray liquid rather than vapor. If you find the leak the high idle will drop momentarily when you hit it with the brake/carb cleaner. ....and you should be able to repeat it every time you hit the leak. 
    As mentioned.....starting fluid is a little too wild for finding intake leaks. I think you will have better luck with brake or carb cleaner. 

  22. Thanks
    Logan got a reaction from BodybyFisher in TPS and ICM Question   
    The high idle issue is likely related to the the TBI being removed. Maybe wrong gaskets. ....Personally I use brake cleaner or carb cleaner to find vacuum leaks....IMO starting fluid is a little too dicey for spraying around. 
    Some codes will not set if other codes are present. 
    Its possible there are additional chewed wires. Or maybe a broken coil return spring on the throttle body shaft.
    Being a '96....the car will be using a IAC speed motor. Lacking a scan tool....There is a Kent Moore tool used to diagnose idle speed problems.  J-37027-A.
    With the tool...you unplug the IAC....the tool works as a IAC driver. You can cycle the IAC open and closed independent of the PCM.....very easy to change engine speed with the tool.  So if the IAC is cycled all the way closed (low)....and there is still high idle speed....there is a vacuum leak. 
    There is also a noid light that plugs into the vehicle side harness. The noid LEDs will blink green and red all the time to verify the PCM IAC drivers are ok and are trying to control idle speed. 
    The tool comes with 2 noid lights depending on which type of IAC you have....the square 4 plug version or the flat plug in version. 
    Most of the time I use the tool to pulse the IAC apart to clean the shaft.

    Logan got a reaction from rockfangd in How to start a tight remanufactured engine   
    There is a range of timing adjustment for the distributor. 
    That range is often limited because of the vacuum advance and nearby obstructions. (intake manifold, firewall etc)
    If the distributor does not get 'timed' correctly with the engine.... within that range....you can get slow cranks. 
    So you may have to pull it out several times.....and mess with the drive gear slot... to get it timed in correctly with the engine.
    You really cant just drop the distributor in and crank it up. You do have to fuss with them a little to get it set up right.
