Hi, I’m Ron and I can help you.
I have been in the auto repair business with my own shops since 1975 and also teach automotive repair. I am confident we can resolve your problem together. Please understand that I don't know your skill level. In most cases when you have a problem with the way the vehicle performs, specialized tooling is required to acquire computer data/information or engine testing results. We didn’t build these complicated vehicles; we just diagnose and fix them. Also understand that I can't see, smell, hear, or touch the vehicle either, so it may take a few replies to get to satisfactory results. I am also going to direct you with the fastest, easiest and most common things to check first. Please be patient and permit me to do what I do best.
I also try to give all of the information you may need, expecting a “positive rating” in return. I will also continue assisting you after you have rated me, if necessary. If there is any reason I cannot get a positive rating, please let me know why “in advance”, so I can go another direction for you. I am sorry you’re having this problem; I’ll help you through it.

The best thing to do at this point is to check the fuel pressure and volume with a gauge, this will confirm a fueling issue or rule it out in case there is another problem that can be found with a scan tool.

Thanks, Ron

hi ron what happens if a 2000 cadillac deville dts model runs completely out of gas when I turned the key I didnt hear the fuel pump.turn on thecar hasgoogle 199k miles but has run and shifted smooth with as far as I can tell no problems
Expert:  rpmdiag replied 7 months ago.

There isn't anything common to that problem, any car has the potential of this happening at any time. Parts do fail. This is why the importance of the test, if the pump is pumping too low, it needs to be replaced, BUT, if it's NOT pumping at all, then it can also be an electrical issue or a bad computer.

Thanks again, and please don't forget to rate me and keep this link in case you need me again later on.

Ron
