p2291

Truck wouldn't start with command start this am. It started when I used the key, gave code P1000, p2291.

The truck was plugged in at -6C. No codes prior.

08F-350 Job 1, Spartan 210, downpipe back 4", S&B intake.


Could weak batteries contribute to this or do I have fuel pump problems?

Thanks

So - I replaced both batteries and everything was good for a couple of days. This morning, I hit the command start and same thing happened, same code. Cranked the truck 2-3 times longer than normal and it fired.

Now I'm thinking lift pump. Any thoughts? Is it the lift pump or the HP pump.

Hopefully you got it fixed by now, but just in case you didn't:

P2291 Injector Control Pressure Too Low - Engine Cranking - This error occurs when enough injection control pressure to start the vehicle cannot be achieved during cranking. Low pressure fuel system, HP fuel system, FUP sensor and wiring to sensor, battery voltage (crank speed) Have you cahnged the fuel filters???

Thanks Mick - Still not fixed.

I put in new batteries because I thought it was not cranking fast enough, that helped but did not fix the problem. Next I changed fuel filters, which has helped, but still not fixed the problem.

I took the truck into an independant shop and they concluded that the HP pump is getting weak. I have to decide if I want to put the truck in the shop for a few weeks (that's how long Ford wants it to even diagnose) or just pay for the repairs.

Right now I'm considering just driving it until it dies. In the mean time it intermittantly throws a p2291

Don't wait too long. Sooner or later it will not start and leave you stranded......... Hopefully if it happens you'll be close to home!!!

Yeah, I'm still limping it along, hoping to get it fixed in early March when I have some days off.

In the mean time, it has occurred to me that the diagnosis from the shop I used does not make sense.

They said that it was the injection pump that was weak and only supplying 3.5-5 psi instead of 12 psi. Shouldn't the injection pump be pushing about 5000psi at idle? That's what my DD is showing me for rail pressure.

It would make more sense give the pressure that it is the lift pump. Does this make sense? Thoughts?

The specs on the low pressure fuel system is 3psi. +/- .5. So your low pressure side is fine. It sounds like the problem is the HPFP.
