Re: Help With Starting a 1990 302
try hitting up the shifter. my truck had a similar issue, and i replaced the battery and battery cables. then i found out that it wasnt fully in park and was shorting out the system.
also check the alternator. the old owner of my truck told me it had a new alternator, but it didnt. i jumped the car to get it going, and watched the voltage meter. it was going down, so i knew the alternator wasnt recharging the battery. i replaced it and it works great now.
