And if the system requires a scanning device that doesn't matter to you
apparently. I should be able to determine what is going on in a
programmed system with just looking at a dvom.

And for the Renix MFI that REQUIRES the correct scanner.

Again, you have no concept of living on a fixed income and that shipping
costs are often higher than purchase prices or the cost of the trip to
drive somewhere.
You have to have a "low quality" tach to hook one up, don't you think???

Again, you're being an ass. After the EPA took over the auto industry,
shops wouldn't hire mechanics without certification and I was too busy
trying to care for a family to be gone to a tech school not that there
were many in the 70's.

Try searching for my email address instead with the newsreader.
The "Extremejunker" was a joke and you took it literally ... 89 XJ, 89
Cherokee should be good keywords just look for posts from the email
address at the top of this post, which is a real email address.

Really??? If you were a physician I'd tell you your bedside manner is
atrocious.
BTW, I never claimed to a "professional" just trained and experienced.
OTOH, YOU asked about a "qualified" mechanic, not a professional.
What did you mean by "qualified"? A diploma mill "graduate"?
I ain't one.

And you really think I haven't checked that? Spark:yes, fuel:yes,
injection:yes but that is while I'm cranking it, not while it's cutting
out because I cannot check those while running easily.
Oh, and fuel pressu on a carbureted engine we looked for a certain
volume in so many seconds into a glass container but with the Renix,
depressing the Shrader valve on the fuel rail 30 minutes after shutting
the engine down causes a fine spray 2 feet long past the driver's side
fender (to prevent fires from the hot exhaust hear right under it).
According to other Renix owners that would appear to be 30 psi or more.
Operating pressure is 31-39 psi.

You don't retain what you've read, do you? The scanner, as I repeat
myself again, for Renix MFI systems, when I last checked 4 years ago,
was not available readily and that the cost was around $1500 US and only
reads codes while the engine is running.
The money I've spent is the total since January of this year, and not a
one lump sum.
