I have a 1989 Chevy Corsica 2.8 V6, that has about 158,000 miles on it.
These miles are mostly highway as I drive a 100 miles (65mph) to and
from work. Anyways my problem;
The car will not start. I have spark on each cylinder wire. I have
pulled the plenum to get to the fuel injectors. Each injector fires
(used baby jars to catch fluid). I also checked each injector wire with
a injector noid light and each injector wire lights. I have 45 pounds
of fuel pressure at the rail. I have a 12 code from the computer, which
says everything is fine. I drained all the gas and replaced with three
gallons of new. I figured at this point it has something to do with
timing so I proceeded to crank sensor. I got that out and replaced it
as it was cracked but it still tested good. Still no start. I am moving
to the DIS Module as it controls timing and injector-ECM firing under
400 RPM. I am also going to test the temperature control sensor. Does
these seem like reasonable tests?
I have done a compression test on 2,4,6 and they read within spec
according to the factory spec manual (100 pounds minimal) with #2 being
the lowest at about 110 pounds.
The problem began when the vehicle was at 65 mph and it died out
unexpectedly. About a hour later it drived fine and I drove it another
week about 600 miles with no problem. I parked the vehicle to change to
my summer vehicle and a few months past, now it will not start at all.
Any Ideas? Please help.
