I have a Chevy express 02 4.3 liter cargo van that keeps blowing out ignition coils, installed two used ones and now a new one and after i drive it 15 mins it wont start back up.

you cant miss the filter if you go under the van

ECM may require a CKP relearn. Use of scanner required.

Fixed Problem (it was my van) no power to ignition wire at starter. Replaced Ignition lock cylinder. just worn down. (Delivery van 50-60 starts a day). 160k miles.

Yes you should be able to replace the coil yourself.Just remove the engine cover.Disconnect the electrical connectors from the coil.There are only 2 10mm bolts that hold the bracket down.The ignition control module is also on this bracket.Just drill out the rivets from the coil and install the new one.The new coil will have bolts instead of rivets.Remove the coil wire from the old coil.Make sure and add die electric grease to the coil wire.It will be included with the coil.Hope this helps.Good luck.

Start with fuel system. Listen for fuel pump humm at fuel tank No humm check wiring to pump for power. Then check for spark at plugs and wires. Remove wire from coil and hold near engine and see arch when you crank. No arch. Replace ignition Modular inside distributor cap or cap or rotor

yes they will fit. be careful use all the suspension parts, life springs coils a-arms upper lowers its a all day projected get a coil spring compresser

locate chime under dash and remove it

you may want to check out the wiring of the starter and the ignition system if there are some open wires which may cause a short...  if the fuse that blows up if for the ECU, you may check out the main wiring that goes to the ECU if there are open wires which may cause the short.

Have the blower motor resistor checked.
