I have a 1990 GMC SIERRA 1/2 ton shortbed stedside With 125k
the engine is the original 350 w/tbi and 700R4 Tranny.
the problem i have with this truck is that when you go to start the engine you have to crank it for at least 5-7 seconds before it will start.
It runs excellent after that but when it comes time to start it same problem.
I have replaced the following parts , fuel pump/sock(old one wore out) and filter, ignition module(old one broke), cap/rotor, plugs ,wires, air filter, tbi to intake manifold gasket,.
when you drive on a long trip oh say 50 or more miles,
you go to start it and bam! starts instantly!
this truck get good mileage for such a large V-8
(18-20+ mpg highway) and idels very smooth.
it does have the ole small block chevy valve stem seal problems and uses maybe 1/4 to 1/2 half quart of oil every 3000k,
not bad for a 15 year old truck that used to tow a 25 ft 5000 lb
travel trailer (previous owner).
Does anyone know why it starts like this?
Is there a way to fix this problem?
Any one else have this problem?
One other thing has anyone elses white paint turn to $#!*
my bed paint is still good but the cab forget it
thanks in advance
