Fuse #29 keeps popplng when i turn the key on

Fuse # 29 on the interior cabin fuse box. 5 amp factory fuse.

if it keeps blowing the fuse, Remove the column shroud covers and repair the wires where they come out of the shifter arm. You'll find they're rubbed against the column and have worn through the insulation and causing a short to the column. Common issue.

replace the relay, jumper wire wont work, there is a small set of points inside the relay, there probably burnt, or stuck open

The easiest way is to power this system (everything on fuse 29)with a relay that supplies power only with the key in the on position.

This fuse powers the coils but also goes to the transformer capacitor. Trace the purple wire from the coils to find the capacitor. Disconnect the capacitor and test with an ohmmeter. The resistance should start at zero and climb to infinity. If not, replace the capacitor. If the capacitor is good, unplug all coils, put in a fresh fuse, and turn on the key. Check the fuse. If it burned, you have a short on the wire. If not, plug the coils back in one at a time, and check the fuse each time. If the fuse burns after plugging in a coil, replace that coil. Does this make sense?

Should be fuse 29, under hood fuse box. Goes hot with the key on.

There is an early and late build for your truck - the early version shows a 5amp fuse number 29 that is hot when the key is on - it powers the 4wd switch and is one of 4 power sources for the 4wd control module.

Pull the EFI relay, replace the fuse, and see if it blows when you turn the key on. If it does not turn the key off, reinstall the EFI relay and remove the circuit opening relay/fuel pump relay. Turn the key on. If the fuse blows than we know the problem is One of the O2 sensors, the IAC, the purge solenoid, or the ECM You can unplug the O2 sensors, iac, and purge solenoid. Replace the fuse, turn the key on, and plug them in one at a time until the fuse blows. Replace that component. If the fuse blows with those unplugged than its probaly the wiring and possibly the ECM. let me know what you find and I'll help you more if needed.

First check to see if the fuel pump relay is bad. Does it sound like the pump is running all the time? The fuel pump should go on and off when you turn the key on and off. You should be able to hear it. The fuse pump relay is located in the fuse / relay box under the hood it should be 29. Hope this helps.

I am sending you a diagram, but in case it turns out a little small you need to check the following fuses.
1. Engine fuse block fuse #1 and #29. #1 is a 30amp and #29 is a 15amp. (under hood location)
2. Instrument panel fuses #1 and #9. These are in inside fuse panel.
3. The radio lighting feeds from under hood fuse #20 which is a 10amp.
This should get you going if the schematic is small. Best of Luck to you..

fuse # 29 in the dash fuse block is for the ECM. gasoline-15A, Diesel-10A
