Fuel filter?

[Gromm]

2004 lesabre custom
Car has died while driving, starting back up after going in neutral just fine, and a few times I have had to give it some gas to start it. Got a number of codes p00d9 p1200 p0107 p006a p0500 p0118 and c3e04
I think I changed the fuel filter a couple years ago, but I am hoping it’s not something more serious. Anyone seen all these codes together? The car does seem to run fine other than unexpected dying. Going up hills doesn’t seem to be a problem either

Start with the lowest code, Google it, and follow the suggestions.

OBD-II Trouble Code: P0107 Manifold Absolute Pressure/Barometric Pressure Circuit Low Input

Looking at the data I’m guessing it’s the MAP sensor. It stays at a constant psi while the car is running, and it has the reference 5v getting to it. I have one ordered and will see how it goes.

I just posted a long post about this on a separate thread. I had a somewhat similar situation. I changed the fuel filter and still had the issue. I took the cap off the pressure relief valve located on the fuel rail and gas poured out. I replaced the shrader valve and it was fixed. The tool and the valves cost $5. Your problem might not be as simple as this but it's worth taking a look.

Do you remember what the post was titled because I have not found it yet.

He hasn't been here in 1 1/2 years. Did you look at this?

You are going around in circles & throwing parts @ a problem without proper diagnosis! There is no mention of any codes? The fuel pressure test port valve has nothing to do with the problem you mentioned, unless it is leaking fuel! Do you have a scanner & fuel pressure tester?

I mentioned in the post after the main post that it's not giving any codes. I have a cheapo OBD 2 scanner. I'll double check to see if it does fuel pressure. I just remembered that I have a blutooth OBD2. Maybe that will work. If not I'll buy one. It runs fine soon after driving so I'm thinking the fuel pump...

Only way to check fuel pressure is with pressure gauge. Part stores rent them out for free just give them a deposit . Remember screen on bottom of fuel pump can be clogged as well , just as bad as clogged filter .
