Error codes (stored) found

[Raven SHO]

Ok, so week and a half ago, my 89 SHO, which has been great since I got it in August, wouldn't start after starting just fine 5 times that day... Then 4 hours later, started right up. The failure sounded like it caught just fine, but then just wasn't getting any gas.

Finally checked error codes on Saturday, no present codes, but stored codes were:
KOEO - 22 and 95
KOER - 13 and 77
Cylinders are fine.

Any thoughts? Poor ground on fuel pump?

Thanks, Mike

22 = BP out of self-test range
95 = fuel pump secondary circuit failure
13 = cannot control idle speed during low speed portion of test
77 = brief WOT not sensed during test

There is a good chance that the BP sensor is bad, giving you the 22 code.
The 95 code gets set when the engine dies for any reason, so generally it can be ignored.
The 13 code is generally due to a sticking IAC.
The 77 is usually operator error during the test.

None of those codes address the issue of randomly not starting, so that points toward the crank sensor as being sick. I would change that next.
