95 Blazer 4dr LT replaced spider, ECM, cap & wires, fuel pump & all filters just over 20K ago. about 5K back the fuel pressure regulator started acting up so I updated the spider with the LTS kit that lets you adapt the later model FPR to the 1995 system. Now the car runs fine when cold, but if you drive it for 25 miles or so and turn it off, it will not start until you go thru 8-10 cranking cycles. I have not had a chance to check the fuel pressure when this happens. The fuel pump is a GM part and should have lasted longer than 20K. what are your thoughts.

 

Check the fuel pressure. Did you replace the internal fuel lines when you had the spider out for the FPR update?

 

Yes I did the new hoses with the spider. I will run it tomorrow and get it warmed up and check the fuel pressure when it fails.
