it's one of those things that comes full circle to bit you. all the wisdom you have, still leaves one open for unforeseen events. The Old got-jah trick. .
I have a good, Twice I worked the cat dealers, Reman, Power Trains, Hydro Test bench, 8 speed trans rangs piston pumps, all manor cat gear pumps diffs and so on: m
Now before you can send it job back to it's customer, you need to close it up, & cover / put
caps in the ports.
Here ten years later, working for a Contractor out in the dirt, I get a remanded gear pump,
thee, face mount, two lines & a test port, painted like new, Only this time, my lying eyes
/ brain failed to compute, that drain plug looked just like a real iron pipe plug with a square end on it for a wrench. I went it, put oil in the system put the floor back on & sold it as good to go,
it lasted for a few minutes & of course blew, a 100 PIS there about hydro-oil is blowing out,
I got the call, the super came by to ask me why I put a plastic plug in, of course I wouldn't had done that, the Old Got-Jah trick, happens. I spent years keeping fleets of 666 scrapers
& 57 scrapers going, 641 A-s were easy stuff, I haven't seen any in years, easy maintenance,
We moved dirt. NY state never was much for serious dirt work, went where the money
was.

Eric, I've posted on another of your vids before concerning this same approach before but it needs to be restated: Always start with a test light and checking fuses. Pull/print diag info showing fuse & relay box locations & layouts. Normally empty sockets are usually noted, as well as what slot is what - what fuse or what relay & what slots or relay positions are used or maybe not used on the specific model, trim, options, etc. Printer paper is cheap. If - ultimately - you suspect, say, an ECM/PCM problem, you pull the pin out diagram for that ECM/PCM to check for the number of power and ground & pin numbers [locations] of power and ground pins before actually checking for all power & grounds at the module, no? Yes, you diaged repaired the customer complaint in about the 1 hour diag window, but you could have done so in 10-15 minutes and moved on to the next car and possibly another 1 hour minimum job a lot sooner. Maybe I'm too 1999. Time used to be money. Thanks for listening.

A guy that goes to car auctions told me that is a very common trick. Someone looks a car over before the auction, decides they want to bid on it, and then pull a relay or fuse so it will not start. Then it has to be pushed onto the auction block and since it's not running, the bids do not go as high. So they get it cheaper and then just plug the relay or fuse back in and pat themselves on the back. Apparently they got outbid on this one even though it didn't run.

I own several Panthers, hence the name Panther Platform, and the most common problem I've had after long term storage is a stuck fuel pump. I simply jump it at the driver module pin connector to free it and she's good after that. They're all rust free too which eliminates a lot of problems.

I once had a cam sensor left bank (4. 6 3 valve) fault and it turned out to be an alternator rectifier failure spitting AC into the circuit causing the cam sensor fault. Replaced the alternator and all is well. :-) Always follow the trail to find the real problem. :-)

I have a crank and no start on 95 town car. I don't trust any of the mechanics around here, been burned a few times. Is it worth starting with just replacing all the fuses? I have fuel pressure and spark to spark plugs. Thanks for any guidance.

I checked all fuses and most relays. I still cannot get my car to start. Has battery checked. I have replaced my fuel assembly. And a module that makes sure fuel pump gets right amount of volts. I replaced fuses. Relays. I cant figure it out

I am pleased that you published this video. It shows the short falls of many diagnosis methods but highlights the challenges of the modern car. I would still have you work on my car. You showed integrity all the way through. Love SMA

I'm not a mechanic. I learn a little something from every video you publish. I learned a little more from this one. Glad you decided to share it. Love your diagnostic process. even if it ended up finding a pulled fuse. Thank you.

This was a great video. The fact that it turned out to be a missing fuse is irrelevant. The process you took to locate all the powers and grounds from the wiring diagram was priceless to learner.
