Customer Question

Expert:  Gary replied 1 year ago.

how long will a new coil last ? is it a GM coil ?

what size engine is in this truck ?

Customer: replied 1 year ago.
A few months. A 5.7 liter and yes a GM coil pack
Expert:  Gary replied 1 year ago.

are any of the terminals melted on the electrical connector that plugs into the coil ?

Expert:  Gary replied 1 year ago.

what year is this again ?

Expert:  Gary replied 1 year ago.

they did not make a 5.7 in 2010

5.3 or 4.8 ?

Customer: replied 1 year ago.
Sorry. 5.3. No melted wires. 2010
Expert:  Gary replied 1 year ago.

if there is no melted terminal or wires on the connector then the only thing to cause a new coil to fail is a defective coil or that coil building up too much head from high resistance from the spark plug or spark plug wire OR one of the terminals in the connector not making a good connection at the terminals in the coil which usually using something like a dentist pick tweak over the centers of the female terminals in the connector until they are just about closes up visually so you know when plugged in they will make a good connection

the best bet is to pick up another GM coil tweak over the terminals and replace the park plug and wire out of that coil

that should correct this issue as nothing else can cause this kind f issue
