Instead of firing the parts cannon at the truck and emptying your wallet in the process, you need to find out what you're missing. Engines need fuel, timed spark, compression, and air (a 5th element is the ability to move said air in AND out - a severely melted catalytic converter can cause a no-start, too). One or more of these could be missing. These days the most common are fuel or spark.

 

If you can get the truck to run on something flammable sprayed into the throttle body - brake cleaner, carburetor cleaner, acetone, ect. - then you've eliminated everything except for fuel. If you live by the motto, "Test! DON'T GUESS!", you will be much wealthier, and be back on the road sooner. If it doesn't run on something flammable, then you need to physically check for spark, injector pulse, fuel pressure, and compression if all else checks out.

You already changed the fuel filter because there isn't one.

 

The fuel filter is the sock on the fuel pump. There isn't a separate fuel filter inside the tank to change.

Rockauto is not always correct with their listings. Only way it should have a filter would be if it had flex fuel capability. when they went to return-less fuel system in 04, external filters filters were dropped

txab stole my thunder. Was just going to say, RockAuto lists a carburetor for my '86 Grand Marquis. 1986 was the SECOND model year of fuel injection in that car. Was the first year for sequential multiport. In other words, there ain't no carburetor on mine, lol.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Disassembly may be Required!   Every blender makes claims but do  you ponder those claims? What was really said? Was it true?  Motive for saying it? What does in infer?  Is that inference true?    Let's do one.    Claim: Made from shear stable base oils.    What was said: Base Oils are shear proof.   Was it true: Yes.  ALL base oils are Newtonian.    Motive / Inference: To imply the fully formulated product is Shear Proof.    Is the Inference true?: Most fully formulated multigrade oils contain Viscosity Modifiers or VM's, sometimes called VII or Viscosity Index Improvers. There are four types. One is in fact shear proof but it also has a bad effect on extreme cold flow and is restricted to use in specialty oils. A second has limited shear called a 0-5 SSI polymer. Meaning its shear is limited to a range of zero to five percent as reported by the ASTM D6278 Shear Stability Index test. A few high end oils, like Torco SR-5, use them and brag about it profusely. Actually all that use it point it out. The last two shear dramatically and are often marketed as a 'feature' of the product aiding the oil to meet fuel standard requirements of ever stricter rules. One shears more than 5% and the other up to 20%. As you make guess, cost is directly linked to shear down and as such the majority of oils use the cheapest organic polymers sold to make grade and pass stringent tests.    PPD's or Pour Point Depressants also shear a bit, only a few percent and hide inside the 0-5 SSI capabilities.    The blender knows he can not out engineer Stribeck. Physics is not a suggestion. But he can wordcraft the unsuspecting toward believing a false claims INFERENCE. This is LEGAL. It is COMMON, and it is EFFECTIVE.

      2006 Silverado HVAC sensor location in dashboard

      I don't recall ever dealing with one on an '06 and back. It may not even exist on that. I can't remember for sure.   Any kind of ice in or after the evaporator is normally due to low charge with both a clutch-cycling orifice tube system, and a TXV system.

      HighMileage oils or stay with Dexos 1 ?

      Engines wear. It is unavoidable. So the question isn't if it will wear out but rather WHEN it will wear out. That question is about rate and RATE is a HUGE problem for almost everyone; but not in the way we may think.    Unless there is something drastically wrong with your powertrain, wear is exceedingly slow. It doesn't wear out in minutes or hours or days or months but in years or even decades. Ditto sludge and varnish. Humans are an impatient lot so to see the benefit of a truly superior product you may have to wait a very long time. Most will get bored first and trade before they reap the benefit.   Humans are not companionate creatures when it comes to those we do not know. We don't care what happens to the second or third owner as long as it doesn't happen to us or someone we know and actually like.   Sad commentary on humans but it is what it is. That thus, then, there is no advantage...to or for you if the above paragraphs adequately describe you.    BUT if you are a buy and hold type and patient enough to reap the rewards of your labors then that thing that is happening that you haven't yet seen, but will; can be abated by such products. Seals harden and leak with time and lots of it. Rings stick after thousands of miles of a slowly building plaque of varnish.    Then there is this. This didn't happen over night and this poor fellow knew when he removed the cover and not one second before.   Not "aware' isn't the same thing as "isn't happening".        The above was typical of the Ford 361 and 391 bus motors on Bulk Pennzoil Mineral Oil products on 3K mile OCI's at about 60K miles back in the 60's and 70's at the Anamosa School District when my Uncle took over their maintenance program.    This is Pepper at @ 165K on 5K OCI's using Group IV/V Full Synthetics.      HM oils will help the first but not the second.    Then again if one used..... ah, ya know.....

      Awesome you got it sorted! That's a new potential issue I'll have to mark in my book of issues. Thanks for the feedback.
