My Nieces 2003 Pontiac Alveno, Starts, runs for 2 seconds then stops, her boy friend have been shooting the old parts cannon at it for 2 days, Hes replaced complete Ignition switch, TPS, Fuel Regulator. Still same problem, since we dont have a fuel pressure gauge, I tried just pressing in on the valve stem, seem to have alot of pressure. Can it still be low fuel pressure. This thing is driving us nuts. No Money light. Nothing came up on the scanner at all. 2 seconds then dead. Gotta be the fuel pump.
Also good air flow through exhaust pipe. I was thinking plugged cat. If you spray starter fluid into intake before it dies, it will keep running. Gotta be fuel pump, tho it was replaced 2 years ago.

You make installation of rubber exhaust hangers easier with a spritz of brake parts cleaner. I wonder if it would rejuvenate the diaphragms in the HAVC Programmer Module? My '89 Reatta uses the vacuum system, too. Same color vinyl hoses, the '88-'89 Programmer is a small box, behind the glove box, between the ECM and BCM. The '90-'91 Reatta is in the dash like this Vic. My '77 Cutlass had a similar vacuum system, as many cars did/still do. I think they are pretty reliable, and simple to service; on some models- the actuators are inaccessible unless the dash is removed. Why don't you like the system? I do admit- nothing beats a lever and cable control. the good 'ol days!

Completely unrelated comment to what your AWESOME video was about. Do oxygenated fuels (i. e. gasoline with 10% ethanol) throw off the long-term-fuel trims on a modern car? I just had a vacuum leak repaired, and the long-term fuel trims were still around +25%. I threw in some mid-grade gas later on, and the long-term fuel trims started going -10%. It might be because of computer re-learn, might be because I threw in non-bargain brand gas, might be because the engine was warm. dunno. However, I'd like to know if 10% ethanol gasoline would possibly cause a lean condition in the engine and positive long-term fuel trims. Thanks!

See this quite often. New or reman unit is for sure the only way to go on a CUSTOMERS car. Yall think Eric O doesn't know you can definitely remove the solenoid pack and replace the o rings but its not a good move for a shop and Eric O knows this. I've done a few including 2 of my own. 98% of the time o rings get her done. But that 2% where a floor light now flickers 3 times a month and the customer just cant live with it anymore, will make you slam a module in it lol. Get it done the first time.

Hey buddy thanks for the solution to fix this on '02 F150 Supercrew. Now maybe there is an easy fix for my temp control issue now, bought brand new OEM blend door actuator and put in a new blend door but I have very limited temp control range such as all the way cold and maybe a few temp degree increases such as 70, 75 and 80 is all the way hot and it should be all the way hot at 90 I tried recalibrating the EATC and didnt seem to do anything and there isnt any codes.

Great video. subbed. They definitely make it so it's not worth your money to tear the unit open. the core price is gonna drive up the junkyard prices too. Don't get me started on '90s Taurus VAPS or blower motor speed control. enough to say that when I sold the Taurus there was a blower speed switch in the glovebox.

Automatic climate control with vacuum actuators, wow. Those vacuum systems were pretty hokey but hooking electronic controls up to them is something else. I'm assuming that Ford wanted to offer automatic climate control but didn't want to spend the money redesigning the whole system on an aging platform.

Didn't read all the comments, but there's gotta be a way to dicker the head unit to fix it's fault! I'd play Frankenstein to try to fix it. You should try it and show it. But the damn thing has quite the core as you said. I hate the fact that parts are designed to fail!

Changed a few of these. Great Video! Installed a few of the round plastic vacuum containers on vehicles that had none. That kept the system working. The check valve and LONG vacuum hose are no substitute for the vacuum canister.

Man, you my favorite digital mechanic. Ever thought of doing an on site series. I have a Titan that needs a blend door actuator replaced. It is a serious pain. anyways carry on and keep fighting the good fight
