Sounds like the fuel injection unit. Does it have the spider type unit that is inside the manifold?

Yes it has the spider type

Yes it has the spider type


On my 98 blazer i had one injector that went bad and it was the #1 and it gave me the same engine code that you had, Thought the spider is a little different from the 95 i think.

On my old 95 that had the votex with the big aluminium intake, It started to barely run unless it was reved up. I opened the top of the mainfold which only take about 20 mins and found that the main fuel line that goes through the manifold and feeds the spider had a hole in it. I turned the key on and fuel shot out so it was dumping fuel in the intake.. It was an easy fix, you have to go to the dealer and i think the part was about $50. Hope this helps..

95 and 98 are totally different systems. Have you checked fuel pressure and leakdown? Takes about 15 minutes and will tell you if there is a problem. Key on, engine off, fuel pump running, pressure must be 58psi to 64psi and must remain above 53psi for 3 to 5 minutes after the fuel pump shuts off.
