Ok my friend, we are going to fix this now for sure. Ok, if you find that the Fuel Solenoid fuse was blown again, here is what we need to do. Disconnect the Engine shut off solenoid. Insert a new 20amp fuse in the f/sol fuse slot. And turn the ignition switch on. Did the fuse blow with the solenoid disconnected?
If yes. You have a short in the wire 339 (PNK) between the fuse box and the solenoid. To break this circuit apart, disconnect the fuel solenoid driver which is located on the same pump assembly as the solenoid. It will have a 6 pin connector with a pink wire 339 also. With this disconnected, put a new fuse in and turn the ignition switch on. Did the new fuse blow?
If no, replace fuel solenoid driver (if possible).
If yes, then the short is still active in the wiring. Disconnect the Engine Harness Connector (15 pin). Try a new fuse to see if the short is on either side of the connector. The 339 PNK wire is pin F of the connector. A test you can do is with the ignition switch off, and the fuse removed, and our connector disconnected, test for a ground on either side of the fuse. The short is on the side that has a ground. I suppose it could ne a bad ignition switch causing the fuse to blow, but I would make sure you dont have a bad wire first.
Now, all the way back to our first test when we first disconnected the engine shut off solenoid and tried a new fuse. If the new fuse did not blow with the solenoid disconnected and ignition swith on, the you may have gotten a bad or incorrect solenoid. I would contact the supply company and see if there is a test you can do on the solenoid to seeif it is bad. Probably a resistance check between pin a and b. Im not sure what the resistance should be, but it should be something other than straight to ground.
My thoughts on this problem are like this. It is a very simple circuit, and if you are still blowing fuses, then something is drawing too much current. Solenoids are usually a good source for this, but lets assume the new one you installed is good. I look at the fluel solenoid driver and possibly the ignition switch. But before I spend any more of my hard earned money, I try and eliminate the wiring for having shorts.
It sounds like you have a hard fault, and if it blows the fuses everytime you turn the ignition switch on, it should be easy to track down the cause. Disconnect the current drawing sources, and then check wiring for faults.
If you dont fix it soon, I am going to have to jump on a plane and come fix it for you. You dont know how frustrating it is to not be able to get my hands on the problem and kicks its but.
