Mid-Missouri | Does anyone have a good link or website for diagnosing early 90's Gm trucks with the throttle body setup. I have no fuel pulse at the intake but plenty of fuel and pressure from fuel line. I have replaced the ignition module with no help. A month ago I replaced the distributor because the lines running between distributor shaft and ignition module were very corroded, causing same symptoms. I have great spark. Ran great for 100 miles. Thanks. | |
