1990 gmc truck 5.7 liter. won't start after throttle body spacer

I have a 1990 gmc truck 5.7 liter. This engine was rebuilt 10K ago. It was running fine smooth and trouble-free until I went to put an airaid throttle body spacer and airaid intake system to enhance power. I followed instructions precisely. When I went to start it up it wouldn't start. Went through and checked everything. Still won't start. Took off throttle body spacer and new intake system, put everything back to stock. Still won't start. One thing I noticed is that I had some oil on my right valve cover. I noticed Pcv valve had come half way out of valve cover. I pushed it back down. Is it possible that pcv could be stuck and pressure pushed it up? Would this cause failure to start? Could an electronic unit on throttle body have failed? Thank you in advance. Hoping to take the kids camping this week.

PVC simply recycles the blow by gases. You have either blown a fuse, or your fuel pump is not delivering gas to the motor.

I have a 93 gmc suburban it starts then dies if I put my foot on the gas to keep it running smoke comes out the muffler and when I take my foot off the gas it dies


Sounds like too much fuel, could be a leaking injector, faulty pressure regulator, or blockage of air intake. Did you replace the injectors and pressure regulator when you worked on the throttle body ? Can you see normal fuel spray on both injectors when the engine is running ?

GMC Yukon showing Reduced Engine Power, broken oil gauge, running hot


I've had the same problem with the reduced power and tps sensor which is your gas pedal. I replaced it but the problem still existed. I then changed the throttle body and harness to the throttle body but still had the same problem. So I traded the vehicle. I did everything the dealer suggested and I just cut my losses. The Yukon overheating would be a different problem and should be easy to fix.
