I think my high pressure pump is dying. My truck is an 87 2.9 4 x 4 ranger. I have a problem that just started a few days ago. In the morning when its cold "30 ish" I have to crank it a bunch of times until it will start. When its warm "50 ish" it starts right up. I did a test KOEO and KOER. The only code was "77" wot. The fuel pressure is running between 29 psi and 32 psi. I know they want to see 35 to 45 psi. The other issue is when I turn it off the pressure drops back down to o. I did the fuel filter after I did a head gasket. The truck runs pretty good. I am thinking that I should change the high pressure pump as well as pull the bed and replace the strainers in the pumps in my tanks. I am told that there should not be a filter in the fuel canister under the truck like my 86 had.
