1997 Chevy Blazer Starting problems

Hi:
If you are getting spark, you need to check for fuel pressure. The pump may be bad or have a clogged fuel filter. Go to this site:

It is a video from this web page that explains how to check fuel pressure. You should be able to rent or borrow a a pressure gauge at most nationally recognized parts stores.

Let me know if this helps.

If the fuel pressure is good and you have good spark, then you either have low compression or the timing is out. If you haven't performed a pressure test, it may be low enough to cause the problem. Also, if you spray starting fluid in the throttle body, will it start and run for a few seconds?
