Hi , i have a 1995 corvette c4 lt1 conv. That i well maintain and keep it in excellent condition, before one year i replaced the following parts, opti spark distributor, coil and coil module , cleaning the injectors before 2 years, new air mass flow, new tps map sensor, o2 sensors, knock sensors,new fuel reg, spark wires, new water pump with temp sensor. And recently before 6 months i changed the spark plugs. Every was fine. Just before two weeks when i was cruising in high way at 65 mph . I've noticed the car seem like it shruged or cut of once and fast then every thing back normal with no check engine light, After that the car started to hesitate or cuts off at idle , and it goes strong little bit when i put the trans on D or R , other that the car runs fine , but before couple of day it shutdown when i was driving it , tried to fire it up i wont the first time, tried again , it want to start but no use , after several times it fired up normal , and took it back home, so i asked around me about this issue they advised me to look for fuel pump problem.
I tooked the fuel pump out the tank the harness was, in great condition , and before i losin the pump i made atest on its pressure it was 36 psi. Idel , with hiiting the gas it jumps to 42 psi, but i replaced any way with new pump , and the problem still there , and still shutdown .
Just for notice no check engine light came at all during this problem .
Need help
I'll be thankfull if you help. Me
