97 blazer 4.3 vortec 4WD 2dr
I was driving around 50mph when my engine suddenly died. I drifted
about 200 feet and parked. I tried to crank my engine but it seemed
like my battery had died. I had it towed to my house and figured out
that the positive battery terminal was poorly connected for some
reason, and that fixed the cranking problem.
Then my car would not start at all. It started to occasionally
backfire. I checked my spark plug wires, distributor cap, and
replaced my rotor. With help I checked my mechanical timing by
finding the TDC of the number one cylinder and checking to see that it
is pointing to the number one terminal in my distributor cap. There is
also a small arrow that is molded in the distributor body that
identifies this position.
My fuel pressure is at about 65psi, and I can smell gas out the
exhaust and on the spark plugs, so that was not a problem. I have a
good consistent spark from my coil, but the spark is not correctly
timed so I receive no spark down my spark plugs. I tested this by
placing a copper wire around the thermals in the distributor cap. With
the presence of this copper wire I get spark down any of the spark
plug wires each time the coil fires. If I remove the wire I will
virtually get almost no spark at any of the plugs and when I do it's
poorly timed. I have replaced my Ignition control module and the
crankshaft position module.
If anyone has the solution to my problem I would be GREATLY
appreciated, and I would willing to give a $20.00 to anyone that
offers the correct solution. I am a college student so I am on a
limited budget and I am really trying to avoid being victimized by a
dealer. Thanks for reading.
