I was given an 02 QC 2wd. It sat under a carport for 2 yrs due to the young man that it was given to not having any interest in it. We pressurized the fuel tank and got fuel up to the VP44. I cracked the return line and ran the pump until fuel ran out of it. Then I cracked the 1, 3&4 injectors. With two hot batteries she turns over with authority, but no fuel reaches the injectors. I am used to working on 12v engines, and know little about diagnosing the Vp44. Could the electronics be bad in the IP? The truck was running fine when it was parked. Thanks in advance for your help!Chris
