tarik Stranger Registered: 10/17/12 Posts: 1 Loc: chicago, il	I've replaced pump, filter, pressure switch, relays, FPDM, tested wiring, diodes, can't figure it out, when car is warm, fires up runs fine, when cold cranking, no start, check engine light codes say low fuel pressure but runs well when its warm anyone with any suggestions??

Old_Guy_Stu Over the Hill Registered: 04/28/19 Posts: 3562 Loc: Cleveland, OH	Just curious, how do you get it warm enough to run if it won't start when cold? _________________________ 1988 CVLX Formal Roof (Love Boat) POTM July '19, Aug '20, Oct '21, Feb '23, 64K E-code lights w/ relays, LEDs w/ switchbacks, 15x8 Ansen slots w/ 255/60 BFG's, Kenwood stereo, various hacks. This, of course, was merely the semi-delirious notion of a fever-patient, but I remember that it struck me at the time as being eminently practical and feasible.
