    Default hard start 88 silverado

    my 88 silverado is hard to start when cold. I changed the plugs, wires, distrubutor, rotor no improvment. I did notice that when oil gauge is all the way up the truck starts up. can this be the oil pump or a sensor?

    Sounds more like you need to check the fuel pressure, and a seafoam treatment, also consider doing a TBI rebuild kit since it may have never been done and the FPR tends to wear out over time.

    Had similar issues with an '87 TBI 350. Problem started after replacing one of the fuel tanks (including the pump and sending unit). It would also run rough just off idle...

    I guess I knocked some old crud loose in the affected fuel lines and partially plugged the fuel filter. Swapped the filter, Seafoamed it, ran the hell out of it, then swapped the filter again to fix it.
