New ECM showed up today took five minutes to put in and Big Pink thundered to life! Thx to everyone who took time out of their day to help, I got the correct answer almost immediately but went my own way spending time and money solving problems that didn't exist but circled back around as I understood more about the system. I will keep that in mind as I move on to other issues.

 

That is good to hear

 

Awesome news.........

Get yourself an old owners manual that came with your truck...Theres a spot that has recommended maintainance levels for a long list of parts in the vehicle with recommendations at the mileages they should be performed too.........Do them all and start over from square 1.........

I keep maintainance logs in Marble Composition books....I currently have like 100 of them too......LOL.

You'll be highly surprised at all the stuff and how soon they recommend doing alot of it..........Timingchain and thrustplate are the key and most important items to replace every 80-100,000 miles too...

How many here change the fuel filter,grease the frontend and universal joints also change their pcv & airfilter plus check tread depth and air pressure in the tires plus checks the transmission fluid level and condition in either a manual or an automatic and how many change their trans filter every 15,000 miles in their automatics and who checks the power steering also the differential fluid levels and changes the diff fluids every 15,000 miles too and who checks their wheel bearings front and rear and inspects the brakes front and rear plus adjusts the rear brakes also rotates the tires and checks the frontend also shocks and condition of the antifreeze with an antifreeze checker plus fluid level in overflow bottle plus refill the windsheild wiper fluid aswell as inspect and replace the windshield wipers also the serpentine fanbelt if needed everytime or every 3rd time they change their oil?...They also recommend checking the torque on key items aswell as frontend components too..

Im pretty sure they also recommend checking the battery terminals aswell as the battery water if applicable and topping off the charge too........I have a Viking automatic charger/float charger that monitors and charges Std and AGM batteries I hook up and the charge is always topped off in less than 30 mins too.......

It also suggests disconnecting the negative while charging and to start over fresh with a fresh ECU memory because it can only hold so much data then drive easy for 10 miles to reset fuel economy or drive it like you stole it for more performance orientation by setting a low mpg rating from hotfoot driving and when you first start the vehicle turn on all accessories and introduce a full load to the system after erasing ECU memory to calibrate the EEC's power and load sensing for the first two mins of vehicle operation..........

How many do those steps too? How many even actually knows all of this besides me?.............LOL.

Thats the maintainance regemine recommended by the good old Blue Oval division though.....On my A9L ECU I had an expanded memory and another square surface mounted chip that name eludes me added in-place of the ones that are slow.....Im pretty certain its called an enhanced watchdog timer....dont quote me but with the enhanced intelligence I can go 3 oil changes without purging the ECU or slowing down from severe buffering and heat build-up that happens when a chip gets full but I still purge it every 3500 miles to keep as much extra memory on tap aswell run as cool as I can......

The bigger program and memory chip would be the big IC in the picture and the small surface mount one that makes the ECU run cooler is in the anti-static bag lower right...Both chips pretty much gave my EEC extra intelligence and stamina as lots dont know or will believe that a full memory chip causes the EEC to run dangerously hot and that emits running problems too...The same exact problems that mimic sensor related issues and highly likely related to your burnt IC's I saw on your PCM.....LOL

Same stuff was basically done by Kenne Bell on my speed density ECU which I still have and one day may even consider parting with it too..............




Heres some very pertinent info on the subject... http://www.auto-diagnostics.info/pdf/ford_eectch98.pdf

Seems rather unnecessary to do almost all of that when doing a simple oilchange and some every 3-4 oil changes;-...right...? Well if you ever drove one from 1 mile brand new you'd highly understand the frequent maintainance aspects thats for sure...I started off with a zero mile and totally rebuilt 91 F250 a year ago....It drives better than a brand new truck and very unlike it did when I drove it for almost 16 years when I got it gave it the maintainance it very much needed also gave it some extra power at 300k which lasted to 565,000 miles...Now I feel like Im driving a Lincoln Continental Sport Coupe rather than a clanky NasTruck.....LOL


I know for one thing and that is I do all that maintainance and thats the fact jack sometimes I skip rotating the tires I hate to say...LOL.....I dedicate a full day to it too.......Im all about vehicle maintainance and when I opened my repairshop at age 18 that was my stich...I pushed the aspects and the importance of proper vehicle maintainance to my customers and I made lots of money sending them reminders and educating them how to keep their cars on the road longer and keep them operating stellar doing seasonal carb adjustments to maintain a good running engine and fuel economy;-$20.00 a pop back then and done in less than 15 mins too..I was literally doing 35-40 cars a day for a few weeks two times a year.....LOL......I made my first million in under 3 years and bought my first house at 19 too...

Heres a slight shot of it with my old SS ...The customized van in front was pretty badass too...I got pics in a box somewhere of the entire build.......The SS too..Its not totally stock...It had a trick frame worked 400smallblock and a super T10 with 3.73:1 gears...At first it was built with a saginaw but I stripped all the teeth ff second gear due to some pretty extreme power....All the detail work was hand painted on by a someone famous here on LI and a few other states who I forget his name but had the initials RR with the first R panted backwards like its mirroring the one on the right as his signature on the lower left of the trunklid and at one time said he did alot of detail work for Motion in Baldwin NY along with another famous guy when they were doing the mako shark projects back in the late 60's and a few years before I peaked into this world and took it by the *****.... ...LOL





Best part was my shop was walking distance and right next to the trainstation parking lot so I got tons of customers and more than 75% became regular repeat customers too who also brought-in friends and family members cars too.....LOL

When in your life have any of you changed brake fluid for recommended periodical maintainance reasons?

I think they recommended back then to change the t-stat and antifreeze plus flush the radiator every 5-7 years too........Who does that...?.

People with the mindset of "If it aint broke dont attempt to fix it" are the kind of people that scare me the most also the reason why most major car crashes happen also why bridges and buildings collapse that hurts n kills innocent people too fyi and the kind of people I deal with on a daily basis too as they would call those recommendations horse hockey and a way to throw money down the drain especially if they have money and can afford a new vehicle every 5-10yrs then its a problem for the next guy or the family that lost someone due to another with the mentality about the adage above when they've neglected proper vehicle maintainance that caused the vehicle to stall out on a dime and cause a crash and fyi thats not why we have vehicle insurance either......90% of inspection shops dont do a 100% honest inspection too and fact...you know why...it takes too much time doing it the honest way. for the $40 bux it costs to get done here..It literally takes an hour....An hour that coulve brought in $80.00 more per so they do them in 10 mins hoping to spot an easy fail to drum up more work....LOL..


Good Luck and rock on with Big Pink..............

 

Excellent advice, it will take a minute to get current but well worth it. Thx

 

This would have more helpful in the thread where you first described your problem but it appears that you multiple threads.

 

Glad you got this one resolved.

 

I have a 1995 F-150 with the 5.0. The Rear gas tank fuel pump went out and the front tank has a leak can I take the pump from the front tank and put it in the rear tank?

 

No the pumps are physically different, the midship tank is taller that the rear tank. One pump stands up vertically and one lays down.

 

I'm somewhat new to posting on the site although I have been lurking for awhile. Thx for the advice, I totally get it if you want to follow from start to finish.
