Ok so I have a 97 Chevy blazer with a 4.3 vortec and 4WD
I found out that I was burning antifreeze and found that my intake gasket was shot so after disassembling everything I saw that the intake manifold was badly pitted so I replaced it with a different manifold from my previous blazer which was the same year and everything. So I put the intake manifold on and reassembled everything, plugged everything back in and went to start it and got nothing... it turns over but it’s almost like it’s not getting gas... so I checked the fuel pressure and it was fine. I sprayed either also and it fire but then kept trying and failed... so I’m kind of stuck and need some advice

If u have any suggestions they would be greatly appreciated. THANK YOU

 

Remove the main injector plug from the top of the injection spider and check for bent over pins.

Did you swap over the entire intake including the upper plenum and injection spider? If so, how did you verify that the injection spider was working?

 

when u say the injecter spider r u talking about where the elec. plug plugs in to the top of the plenum. if so the pins are not bent. and this manifold and plenum came off of an engine that ran
