I guess it was bound to happen eventually.
Started up fine this morning. Drove over to the gas station to get some coffee. Started up again and drove about 500 feet when the engine quit suddenly and wouldn't restart.
Scanned and got a P2294 code.
Pulled and checked the connector to the fuel rail pressure solenoid. Seemed fine so I firmly reconnected it. Also checked the connections to the fuel quantity solenoid and the fuel rail pressure sensor. Everything looked ok but still wouldn't start up again.
I was only a couple of blocks from home so I called my wife and had her tow me home.
So I finally got to use my recovery strap and tow hooks and D rings. Woohoo, :oops:

Still got some more diagnosis to do but I'm fairly certain that I'll be needing a new fuel rail pressure solenoid. :banghead:

I got a friend with the same symptoms. Driving fine, lost power, then died. Same code. Changed fuel filter, started and ran great. Then took it to work the next day and wouldn't start after work. Installed intank lift pump, no joy. Got a crank sensor on order. Snap-on scanner did show good pressures... Following your thread closely now.

Got it running this morning.
Not sure what I did though.

I removed the fuel line from the filter outlet and attached a longer hose to run it into the catch can. Turned key on, lift pump started pumping, and got good flow and clean fuel out of the filter.
So the low pressure side was good.

Checked all the connections to sensors and solenoids
Then cleared all the codes.
And then the engine started right up.
Took it for a short drive, smooth running without the slightest hint of a problem.

The only thing I can think of that fixed it was removing the orange seal from inside the connector to the fuel rail solenoid. I did that on Thursday while I was stuck on the side of the road. But it didn’t seem to help with anything.
But I also didn’t clear the codes.
So I guess with a problem such as this you must clear the codes to get things working again.

Those orange seals inside the connectors have been a reoccurring problem for me.
I guess what happenes is the seals swell up enough to pull the pins off the connections.
When this happens the connector is very hard to remove

Crank Sensors are known to cause shut downs and no starts...

Been there, done that, about 4 months ago.

ARG :banghead: I hate these non-fix fixes. A rubber grommet in the connector? Okay so I will check the connectors I guess, again. Will advise.

It happened again today.
This time it also had a p0087 code.
Didn’t need a tow this time however.
After someone helped me push it safely out of traffic, l cleared the codes and it started right up.

Must be a intermittent loose connection somewhere.
Or it’s a intermittent open circuit inside the solenoid itself.

Now I'm thinking you have a wiring or connection harness fault. Many have seen this picture but at one point this caused the main PCM fuse to blow.

This was passenger side firewall around the A/C accumulator.

I had a similar issue (not identical) couple years ago, with one injector. The wires to the injector plug were messed up, causing a code (really don't remember it) which caused a limp mode. This happened from every 4-5 months to every couple months till it just limped me while on the highway. I tried to wiggle the wires till I found the injector with the issue. I remember it was a generic code and not an injector specific. I had a spare wire harness and I replaced the plug and no issues from that time.

I'm not sure if wiggling the wires would help you with anything, but I'd think it's worth a try.

Check if one of the pins are lightly burnt on the ECM. Seen this twice now, a scrape, slight bend and some dielectric to quench any future micro-arcs or corrosion solved both

Hey Flash,

Something to be aware of on that particular part... In the course of digging through mine, I exchanged communication with Keith from GDE, who, as you know, has spent extensive testing hours, both in and out of vehicles. One of the things he mentioned is, the Fuel Pressure Solenoid, when it fails, often does not fail with a hard fault, but with a pintle that sticks or leaks, or both, which can also cause these symptoms. I'm not certain how to test this, except for similar to the way one tests an old starter motor that might be going out. Might keep that in mind if you don't find any issues with the wiring.
