Compression:
I performed a compression test.
Dry. Didn't do a wet, I was satisfied with the dry.
#1@120, #2@115, #3@140, #4@120. The only suspect would be #3. The rest seem close to normal.
Fuel:
Fuel pressure stayed at 12# running and didn't fluctuate much during revving.
Key on runs pressure up quickly, but falls quickly. No change when return is clamped. Also, tbi is dry during test, no leaks from injector.
I haven't checked the egr yet.
The fuel pressure leaks down so fast, i find it suspect, but stays up when running, so I don't know what to think.
Any thoughts?
