i have a 1996 astro van 4.3 i have been working on for a long time. it will start and continue to run if you dump enough gas down the throttle body to get it to start. i have replaced the cam, crank sensor. the computer is directly under the battery. when the battery boiled over, it had got corrosion in the wires. i cut the wires with corrosion, and spliced a new piece in. once the van i primed and runs it will start and run fine the rest of the day. but next day it will just crank. any information you could give me would be appreciated.
