i have a 1990 buick lesabre motor is a 3800 and it runs fine until the motor warms up and then when i shut it off it won't restart for about an hour after i shut it off. it's not over heating it has a new fuel pump. any advise on this problem, thx joe

i would suspect your ignition module mounted under your coil pack or inside distributor or the crank angle sensor. you can get a bottle of freeze spray to check your module or see if it has any codes

how do i use freeze spray to check it.. this is all new ball game to me. i'm the kind that if it breaks i can fix it, but this is 1 of those things i that i just can't seem to pin down

if its the module mounted under the coils get a can of freeze spray, wait till it acts up then spray it with the spray to cool it back down then try it and see if it starts
