Hello! My name is Franchise Yaj

This is my first Z32 and it started out great. Then, I started having engine start problems from a leaky FPR. I figured out that one of the hose was leaking so I tightened it and everything was getting back to normal again. Little did I know that I would start to get bad engine start again and I started getting bad pulsate when the car idled so I got a new connector and rewired it. So, now that didn't stay good for to long... My problem now is that the car has completely stalled. I was wondering if anyone could assist me with this issue. I've looked around before I made my own post but I get lost real fast as soon as they talk of issues I currently do not have I push the back button and search again. So, if anyone out there that can assist me with this I would appreciate it much.

Thanks,

First steps first. Verify fuel and spark, check ECU codes.

If your fuel pump primes when you turn the key on, fuel is most likely good. You can also pull spark plugs and look down in the hole while turning the CAS if you really wanna get into it. Alternatively, http://www.nicoclub.com/archives/diy-fu ... ester.html

While the plug is out, plug it back into the coil pack and ground it to the plenum by touching the threads. Spark=good.

This is all day-one stuff. If you don't know any of this, you should probably have a mechanic friend helping you, or spend a lot of time in the FSM learning.
