Massive fuel leak into engine and out exhaust

Anyone want to add their 2cents…..
I was involved in a very minor accident last week and rear ended another car, it was during heavy rain and  at a low speed. No visible damage to the other car I hit and what appeared only to be split/cracked bumper on my car (hood/fender still aligned and the headlights not even scratched). As I drove off my car started running very rough and the smell of gas was overwhelming. I had to have it towed to local non-Ford dealership with a GEICO Express. They were supposed to replace my bumper and the padding behind it and look at the motor. The place called me and said the engine was getting a massive amount of fuel, so much so that it was coming out of my tail pipe. There are no damaged fuel lines either. They have no idea what is wrong with it and not I have to take it to a Ford dealership.
Any ideas??
Thanks Gene
 
I would get it right over to Ford.  You need to have someone who is versed in Ford fuel systems go through it. Good thing it didn't blow up! 
 
Sorry to hear about your accident!  We would need to know about your ride (SHO/XSport/Flex...) before being able to comment specifically.  True, you could end up hydrolocking your engine if indeed fuel has dumped into the cylinders.  Would be one of the worse case scenarios.  Scoping the cylinders would be the right thing to do there to verify.

However, if you have tuned/meth'd your ride, and the dealership is inexperienced with this kind of stuff, they will tell you all kinds of things just because they don't understand it.  So, not to worry just yet.
 
Thanks for your input.
    I was able to drive it about a 1/4 before it started acting up and I turned it off to take a  look under the hood. It would not start without adding a heavy gas peddle. I drove it about a 1/4 after it started running back since I was on a curve.
  I’m hoping it’s a fuel regulator issue related to the accident and GEICO will pay for it.

Don't drive it like that you'll hydrolock the motor. :)
No fuel pressure regulator but may have damaged the spill valve on the high pressure fuel pump.
 
The Evap system might be worth a check too, though I do not see it being the cause of a massive fuel dump.  An O2 sensor could be damaged as well.  Either way, pulling the codes should help figure this out.
 
Immediately have it flat bedded to a Ford dealer.  DON'T DRIVE IT..  May be a simple solution to fix but a big problem if driven.  Since you drove it, I would recommend a compression check on all cylinders to verify you don't have engine damage. Been there personally.  I caused my problem but it was due to too much liquid in cylinders.
 
Thank you for your valued input. I only drove it for a short distance 1/4 mile after it starting running bad (had no choice since I was on a wet and dangerous roadway) and have had  it towed now twice.
  I can't express how low of an impact it was...just split my bumper.
  I'm just worried GEICO is going to give me grief cause I modified my car. I spoke with the Ford dealership's shop foreman and he seemed pretty receptive and knowledgeable.
Wait and see now
 
  Hello folks,
  Well I got the call today.....stuck injector. The minor accident I had was the straw that broke the camels back. They covered it under the warranty.
  I was alarmed when they told it had no gas left, it had about 3/4 of a tank when I had it towed o the first place. The same place that could not figure out what was wrong with my car in the first place. I expressed mt concern and hope they thoroughly check my engine.
                  later

 
Sounds like good progress.  Did they tell you when you'll get it back in tip top shape?
 
I'd be careful with that.  Local dealership changed a bad lifter out of my F150 and an injector ended up stuck open.  Long story short, motor gained a knock instead of a tick and was replaced due to the chunks of the piston in my oil pan and bent rod.
 
Probably want your exhaust system downstream of the cats replaced if that much fuel was dumped, in addition to making sure the cylinders are DRY before starting up the car again.

>>> Yea, it's got to be full of fuel.  Wonder if the cats are gone too , especially if 3/4 tank is unaccounted for?
 
The last thing I was told was they needed my permission to charge me $20 for fuel for the test drive etc. I told them I was concerned that 3/4 of a tank fuel was lost at the first dealership and questioned if that dealership possibly harmed my car. They had my car for a solid 7 days and who  know what that did. I expressed my concerns and I hope they do a fair job.
Thanks you all for your replys.

They need to scope the cylinder and piston and make sure it didn't wash out the top of the piston and cylinder walls. Maybe yet got a few gallons of fuel in your oil system if u are missing that much fuel

Agreed, your cats are most likely on their death bad as a result of massive overfueling.  I'd get them to replace the cats as well.
