View Full Version : Sudden Explosions!

So my truck runs fine until it heats up! As soon as it heats up it seems to lose ignition or something, sputters and backfires, like shotgun style! sometimes if i put the clutch in right as it starts to sputter i can catch it, but if i try to keep driving the truck either has no power or stalls out.... its a 92 Chevy 1500 with a 350 throttle body fuel injection and stick shift..... any suggestions?

same thing happend to me on my truck (1992 Full Size Blaze 1500 350 tbi Automatic) and then one day it dies and wouldnt start. it turned out to be my ignition moduel (on the distributor) They dont like the heat and if they are not installed properly with the proper heat disipating silicone they can fail...

the chevy ignition moduels are really bad. They are heat sinked to the distributor, but as soon as everything gets hot, or dirty, or wet, things star to go wrong. I used to carry a spare moduel in my glove box, and i think im gona have to pick up another...

hey larry had something like that on a 93 aswell turns out the distributor was fubared somehow the timing was changing on it's own would have it checked and set proper drive it for awhile and it would be out again. no power then the exhaust manny's were red hot at one piont drive a guy nuts though.
