1125 CR with 19000 miles has not wanted to
start a couple times. One time it did throw
the fuel system pressure error otherwise
it runs fine. So I'm figuring the pump is
giving up. Is there anything else I should
look at?

Was the 12k valve check done?

Sounds like low cranking voltage could be the cause. Test battery and cranking amps

12000 mile valve check was done.
After charging battery was when the fuel
system pressure error popped up. Motor shut
off after error appeared. Thanks for the
ideas.

How do you get into the diag mode?
I don't have the electrical manual
yet.

I understand you had the battery charged, but you still need to have it tested. a fully charged bad battery is still a bad battery

Thanks Dennis c. When I went into the diag
the fuel system showed 440 KPA. Upon starting
it ran for 10 seconds dropped to 0 and died.
Now shows 40 KPA and I don't hear the fuel
pump. Gemini I had the battery tested & it
was OK. Looks like I'll order a pump Monday.
Thanks for the help.

Gunter found some alternatives to the standard pump
http://www.ukbeg.com/forum/viewtopic.php?f=17&t=57 94

should be easier to get and cheaper-because you'll be able to buy just the pump not a complete assembly.

In 10 seconds you should be able to go from 1/2 to a 1 mile at a time then restart do it again. Start it in gear that will help your distance.

Drc there was a thread here recently about fuel pumps if you are adventurous you can grab the aero-motive pump I listed and swap the pump rather than the entire assembly

Boogi -
I may be doing that soon too.
Loretta gets some lift-time soon and I'm going to swap in the take-off pump ass'y I bought last year.
If that doesn't fix my power loss, I'll replace the pump in the ass'y I have out...

Thanks to you and Battyone for your info..

Zack
