I recently replaced the spider injection in me 95 Blazer and put all new gaskets in it when I put it back together. After that I took it for a test drive it worked great. Shut it off changed and then left to go to the store and it just completely lost all power and will bearly run now won't even start most of the time. Anyone have any thoughts

 

If you have a fuel pressure gauge, the first thing to do is check the fuel pressure. You also want to make sure it maintains pressure after you turn off the key. There may be a fuel leak under the intake manifold.

 

I just put a whole new fuel system in it all lines new tank sending unit pump about a month ago I checked the pressure about a hour ago it's all good 51psi checked vacuum and checked for leaks around the intake just pulled the egr cleaned and put a new gasket in it I can't figure it out
