    i cant find the issue here. takes 6-7 attempts to start before it will idle, stumbles throughout throttle range untill warm. then , within 5 miles stumbles and stalls. will not re fire untill approx 20 min cool down, then starts on firstattempt, runs fine for 5 more miles and stalls again. its like clock work. i tried disconnecting E.G.R valve, tested ignition coil, replaced cracked vaccum lines. no help. hard to blame the fuel pump??? or no... please help as this is my only ride. im not a pro mechanic but have done extinsive repairs in my 55 yrs. mostly chevys. just bought this so dont have much history. Thanks much< Richard
