LT1 cranks but barely starts
I hoped I had solved this problem, but I guess not...
95 Roadmaster Wagon with LT1: sometimes starts badly after sitting for 1 or more days. Battery is good, starter motor is good.
Engine cranks and turns at a normal speed, but it wont run.
After continuously cranking for about 1 minute and alternately depressing or pumping the gas pedal, the engine finally catches and immediately runs smoothly, no hiccups whatsoever and good response to the throttle.
If I stop cranking, sometimes the engines gives one `blub` as if itīs just running on one combustion round in one cylinder.
So far Iīve replaced: spark plugs, ignition cables, rotor, rotor cap and iginition module.
