I ran diagnostics and got 1-h74LED display dimming output circuit open or short, 4-h22 tps voltage low and4-h34 map sensor voltage low. Can anyone please explain how I can fix this problem?

Hi, no their was no recent engine work, timing is on and brakes are fine. Removed exhaust to check if cat was out but had same problem. Car starts fine , rev up motor and is responsive, let idle and rev motor and is starving for fuel.

Good morning, I have a 91 vette that starts and will accelerate and then has no power. I changed fuel filter and removed fuel pump and tested. Fuel pump was fine, blow out fuel lines and still has no power.
