I know I have it somewhere, but can anyone off the top of their head give me the firing order for the 4.3? My '91 Sierra just died and I want to make sure I have that correct at least. I just did a new cap,rotor,wires plugs etc and it ran for a while but just died. It will crank and it's getting fuel, but I haven't had a chance to verify if it's getting spark.

It should be 1-6-5-4-3-2

1, 3, and 5 on the drivers side, front to back

2, 4, and 6 on the passengers side, front to back

  Since the media YOU and your buddies are programmed to watch failed to mention this, I'll fill you in. Trump admitted today that we've grabbed 150 MILLION barrels of oil from the Iranian tankers locked in the Strait by our Navy. We turned off their transponders, took them out to sea in the dark of night since they have zero radar capabilities anymore, offloaded every drop onto another vessel, and put them back by morning so no one was the wiser. That oil has been en-route THROUGHOUT the entire conflict. Main reason he admitted this is to let even guys on our own side who joined leftists in complaining about the prices that he hears us all, and has taken steps to make sure this didn't spiral into a BAD situation ... just like the mainstream media has been PRAYING would happen, just so they could gloat. Amazes me how these people are rooting for the destruction of THEIR OWN HOME, just to make a President they don't agree with or like look bad! That's next level TDS! I know your not capable of giving our President the benefit of the doubt, again due to your deep programming, but THIS is why oil never hit $150 a barrel as predicted by your programmers, AND the reason oil continues falling. Like I said before, Trump's got a plan, and this is proof of it. By the end of his term, we're going to be in GREAT shape for a change! Since I just spent $3,000 this week on #2 heating oil and gasoline, the war most certainly is ending! 🤣 https://mxmnews.com/article/ba359ac9-2711-4851-92de-187f2400f2dd?breaking-trump-cancels-iran-strikes-deal-now-approved-by-all-parties
- A/C failure cause???

  No leaks. Replaced the condenser 3 years ago. Problem was found to be caused by the A/C blend door actuator. Just replaced it and it's blowing out the cold air it used to when I bought it.

  Curious, what would you consider a 'normal' AFM system lifespan? How long do you think one without is capable of?
