My truck went pop and quit runnin'. On the freeway, with crazy traffic all around. Fortunately I had just enough momentum to get it into the ivy. There was no shoulder. I cranked it and smelled fuel. Looked around under the hood. Fuel running out from below the FICM. All of the vacuum side lines are in tact and pumping the prime went hard in five or six strokes.

I can't see under the FICM but the #2 injector is under there, fuel rail, maybe the pump?

Three crazy hours later the tow truck drops me off at the dealer. I show the service writer what I found. "cracked fuel rail" he says. Of course the tech might find something else but, this is a large dealer that sells Cadillac/Hummer/GMC trucks and SUV's by the train load. Maybe this guy has seen this before.

Have any of you?

They are way busy and couldn't get to it Thursday or Friday. Monday is my day. I got a loaner so no biggie but, I'm worried bout my baby. Only 31K on the meter so should be warranty, unless they try to wiggle out of it. I doubt that, they did some serious customer service when I dropped it off. Got me water, had Herts bring the car around while they wrote me up, asked me if there was anything else they should look at while they had it! Not at all like my regular (former) dealer.

So that was a plug for Marvin K Brown in San Diego.

Any input on my prob?

Thanks

Seen a few early LB7's crack fuel rails, both sides on one truck about a year apart. Don't remember a new one, though.

broken seal/leaking FICM?

Id bet maybe something (fuel line) let loose in the FICM because the truck immediately stopped running. Ive seen a truck with a huge high press fuel leak (like it was dribbling out fast under the truck) and it still idled, FWIW....

I should know Monday and I'll let you all know. I was wondering if this is one of those common problems that I can expect to happen again. Since nobody chimed in with that kind of post. I'll just try not to worry about it.

Of course when I think that just two weeks ago I pulled my 30' RV from San Diego to Thayne Wyoming then to Boise and back to San Diego. Including a run through the Nevada wasteland. Well, I'm just glad it waited to do it near home.

BTW only once over 210* on the temp gauge (Eighty degree day pulling over the Wasach) tranny never over 200*. I was quite pleased with that run.

well, it was an injector. So yes, it is a common thing that will happen again. Odd, I figured a failed injector would still limp in. Obviously not.

Are they all the same and could one be changed on the side of the road if you had a spare?
