'91 Blazer not starting when it's REALLY cold out.
A coworker of mine has a (I think) '91 blazer with the 4.3L Vortec V-6 in it. He says that last winter whenever the temps dropped below about -25 to -30 that his truck would turn over fine, but it wouldn't fire. Is there an ignition or fuel pump cutout related to oil pressure on these? If so, is it the sender by the exhaust manifold (driver's side) or is it the pressure gauge sender up by the distributor?
