Starting Problem

[fyoung]

My 97 PSD has developed a starting problem. This is not a cold start problem, as it is occurring at 45-50 deg. temps. Cranks over good and fires for a split second and then dies. I'll repeat the starting cycle several more times without it firing. Then I'll repeat again and it fires once more for a split second. This can go on for 4-5 minutes before it finally keeps running. Once started it runs fine and has good power. This original engine has only 63K miles on it. Thought I might have a fuel filter issue. Checked it and it was fine, but replaced it anyways as it was time. Only other problem I've had was the cam sensor, which was replaced when they had the recall.
I've searched the forum for similar starting problems but have found none. Cranking speed is good and oil pressure comes right up.
Any ideas on solving this issue would be appreciated.

When it is not starting, is the tach moving? You may want to throw another CPS in there (if its not the problem you'll have a spare for the glovebox ... never a bad idea!). Cheers!

Yep, tach is moving even when not starting.
