why the INJ fuse keep blowing and how do I find the problem? I done replace the fuse 3 time. no spark no fuel pump sound when turn key on no start. I use my test light to check for a short at the fuse box inside the car I hook the clip end to battery positive and the pointed end to one side of the fuse box socket with key off.

So this happens when one of the injectors is shorting out. I would remove them and run this test from this guide.

So it looks like you have 2 ignition coils that are bad, I would replace them and then clear the codes and check the other fuses.

P0351 - coil A / cylinder 1
P0354 - coil D / cylinder 4

Let us know how it goes.

If you have all the coils codes at once, I would disconnect them and run a test, you may have one shorted coil taking the system down or the PCM is bad. Please go over this guide to help you with the testing.
