So the fuel injector fuse keeps blowing in the ZX2. I'm not sure why this is happening as it just started happening just recently. My sister was driving the car and it just died. Replace the fuse and it ran alright but the fuse blew again. I really want to help her fix this problem because she's driving my car back and forth to work. If anyone has any ideas, I'd appreciate it. Thanks.
Kevin.

I just had the same problem. I have an aftermarket K&N cold air intake for my 1998 ZX2 and the electrical connector on the fuel pressure sensor was rubbing on the hose clamp. It finally wore through the insulation on the electrical wires and shorted them out. Now when ever i put a new fuse in, it blows right away. I dont know why it is doing this and i dont know what that circuit is directly connected to under the intake manifold to check for shorts. Has anyone else had this problem or know how to fix it besides burning the car to the ground?

Thanks,

Kyle

Turns out it was another faulty alternator. I traced the lead from the Fuel Injection fuse under the hood all the way to the alternator. I had purchased a performance pulley for the alternator which makes it spin faster than stock to put out more juice and it also makes it die faster. I replaced the alternator and fixed the short on the Fuel Pressure Sensor on the fuel rail, replaced the fuse and now it works. However, when the RPMs get above 4000, the battery light comes on. I suspect the rebuilt alternators are not quite up to par and can not handle the increased RPMs from the aftermarket pulley. So i have two choices:
1. Purchase the smaller underdrive pulley to decrease the RPMs on the alternator. (about $100 or so)

or...

2. Replace the alternator with the high output alternator that can be found online. (about $320 or so)

Decisions, decisions....

You might want to replace the alternator with another one. Make sure you get the lifetime warranty too. It is well worth the extra few bucks.
