i have a 1999 suburban w/5.7L cranks but wont start checked fuel pressure pumps up to 64psi. And then falls to 54 psi. After which pressure bleeds of faster than I have ever seen in the past. Also had ic code and crank sensor code. I suspect the presure regular but have heard it may be the pump.
have the same problem?
