Okay, first off, I admit I went overboard. I’ve had my ’93 since ’95 and never made any major modifications to it till now. Instead of doing one thing at a time and repeating a lot of the work, I decided to do it all at once to save time. WRONG! Here’s a summary. A’PEXi Power FC, Turbo Timer, FMIC w/Power Intake & BOV, Fluidyne radiator, fuel pump, PIAA driving lights, silicon vacuum hoses, HKS TwinPower, Magnecor plug wires, 3” down-pipe and mid-pipe, A’PEXi N1 dual, Hyper Ground system, and 1300 cc secondary injectors. Now, I have two problems I have now been able to track down.

One is a fuel leak that I can not find. It only happens when I try to crank it over. I can have the fuel pump run and nothing leaks. When it leaks, it drips from the passenger side of the engine, but I can only see it where it is dripping off. I have check all the fuel lines going to, from and between the fuel rails and the injectors, and I can not find anything wet anywhere.

Next, when I connect the battery, almost everything powers up as if the ignition is turned on. It does this not only if the key isn’t in the ignition, but also even if the ignition isn’t even plugged into the wiring harness. The dash lights come on and you get the dinging as if you had just turned the key, but none of the accessories come on.

Anybody have any idea what I am overlooking on either of these?

Thanks,

David

 

Were the upgraded secondary injectors installed correctly? If the o-rings were not lubricated, they could have torn on installation (ouch!, sounds like a line from a bad porno...).

 

I lubricated the o-rings before installing them. I later checked them out and they looked OK. Also, there is nothing leaking around them.

 

My theory here is that your turbo timer is hooked up incorrectly. Recheck your connections carefully.

 

Did you use the harness?? If so, that's not your problem.

 

How does the engine run? For your fuel leak, if none of the hoses are leaking, the only thing I can think of is that one of your injectors is leaking excessively, and the excess gas is either coming out from around your lower intake manifold, or out of one of the exhaust connections.

Turbotimer sounds like the culprit for your other problem.

 

I eliminated the turbo timer early on. I tried everything I could think of before bothering anyone for advice. Yes, I used a timer harness. I have removed the turbo timer altogether, put the original ECU back in. I even went so far as to try hooking a battery up the way it originally was on the long shot that something I did in relocating it had caused the problem. The strange thing is, that it powers up when for all practical purposes, it shouldn’t. I can completely remove the ignition switch from the wiring harness and even remove the anti theft key under the steering column and it still powers up as soon as I connect the battery.

As for how it runs, it doesn’t. I have checked and I’m getting spark, but it never hits a lick. It started fine before I started on this. I assume that this is tied to whatever is causing the power to come on when it shouldn’t.

 

You've obviously got some wires screwed up somewhere, if you remove the ignition key from the wiring harness and much of the car powers up. Without knowing exactly what and where you made modifications, it's impossible for us to offer much advice other than to double/triple check all your wiring connections.

 

Hmm... what exactly did you do to your car's wiring? You say you are getting spark; are you also getting fuel?

Like Kento said, it's pretty hard to troubleshoot without knowing exactly what you did.

 

I’m getting fuel alright. It’s flooding bigger than crap. I took out all 4 plugs that were literally dripping wet. Did the best I could at getting any remaining fuel out, put in a little ATF and tried again. Still nothing – except having fuel dripping off my oil pan before I even gave up on cranking it. I looked again to see where it is coming from. Without pulling the engine out, the best I can tell is that it is coming from somewhere around or under the turbo manifold. Is it possible that the secondaries are dumping enough fuel in that it is not only flooding the engine but leaking out somewhere?

Also, when I got the Power FC, I got the run around about delays in getting it to me, first that they had tuned it for me, then when it came to me from a distributor they claimed that the distributor had tuned it to my needs for me, but when I got it and looked at it, it appeared that nothing had been changed. The secondaries were still set to defaults, not the 1300’s I now have. Seeing as how I got everything from the same place, they knew what I had. I set the secondaries myself, but I have no idea what if anything else needs to be remapped. I have been tempted to reset it to factory defaults and only setting the secondaries back to 1300’s to see if they just completely blew it. Does anybody have a good baseline of settings for me to start from?

As far as alterations to my wiring, the only changes that I made (that I am aware of) are:
1. adding in the turbo timer harness
2. adding the harness for the HKS Twin Power
3. Clipping the ECU wires needed for swapping in the Power FC (Yes I checked umpteen times that I was clipping the right wires by position and color code both before clipping anything)
4. relocating by battery to the cargo area

Thanks…

 

If your engine is flooding that badly, the gas is probably coming from one of your exhaust connections. Maybe one of your injectors is stuck open? Or maybe your messed up wiring is causing your injectors to stick open...

That's a baffling wiring problem. Sorry I can't help you more, but I know almost nothing about the PFC, HKS Twin Power, or a turbo timer.
