Hey guys...I have a 2000 4dr Blazer with 112,000. New fuel pump a couple hundred miles ago. Recently having starting problems...go to start and it cranks over and putters for a bit then nothing...at times white smoke billows out of the cold air intake. When it does finally start...runs rough for a while then evens out after time. Just lookin for some insight on what this is and what to check or change to get this problem solved.
thanks.

 

no guesses?

 

Please give at least 24 hours before bumping a thread. Thanks.

 

any ideas guys???

 

As the start of any no-start diagnosis thread on this forum (and there are a TON of them), test the fuel pressure. New pumps do go bad. Especially if they were an aftermarket brand.

From there, ignition, etc...? There are some very basic checks that you have neglected to state whether you have done or not. In fact, you have given very little information on what you have tried, if anything. In the end, you are the only one that can do the work.
