Finally got it started and took it for a drive, problems.

I have a new clutch, so I was going REALLY easy on it. But it seemed kinda low on power, but that I wouldn't really know since I've never driven an m52 car. But it seemed to take a lot of gas to go uphill at 10mph.

Anyways, it seemed to idle pretty well. But it once it warmed up it seemed like it was kind of lurching or hesitating and I had to stay on the gas to keep it from dieing.

I do'nt have a tach or temp gauge so that makes things a bit harder.

Also fuse number 9 pops everytime the key goes to the second click. However it was running with no fuse there.

That fuse is idle/fuel. So it's quite likely my problem lies there, I just don't know what to check for that fuse. I've looked over everything I've done.

Do you have the right fuse in there? Because you need that fuse. Did you put the FPR in?

[87e30]

Also, once Ihad drive, pulled over and looked at everything made sure it was good. I went a little higher in the rpms and when I let off teh throttle I noticed it backfired.

[87e30]

Do you have the right fuse in there?

I have the correct 15 amp fuse in the number 9 slot.

[e30s52]

Try a slightly larger fuse.

[87e30]

Hmm, 20amp? 30amp?

Shouldn't it run on a 15 f that's what it's designed for?

[e30Rob]

did you do the wiring yourself or did you buy and adapter?

[jahnaboi]

Double check your wiring. If you're blowing a fuse every time on the second click of the ignition, it probably would lay within the wiring.

guess i should have said that rather than just asking if he did the wiring himself...lol

[87e30]

Yeah, people have said the wiring.

However, the only wiring I have done is for the ews. (obd2 security stuff)

The ews is wired up properly since the car starts...

The harness I purchased, although earlier today I took it somewhat apart and all the connections are individually wrapped so I left it at that and wrapped the harness back up.

I don't know where to check in the wiring...


Fuse number 9 is supposedly for fuel/idle so it seems logical that this could be making the car run poorly. But fuel pump, IAC, and FPR all must be working if the car runs.

[87e30]

So I have no idea why the wiring would cause fuse 9 to pop.

Any connections or anything to check related to fuse 9 (fuel/idle) ? IAC and related work since the car did run)

My plan as of now is to try putting in a fuse while the car is running and see if it still pops. And if it doesn't then try a larger (20amp) fuse. Other than that I'm lost.

well if the fuse keeps poping their is a short but ware in the adapter or in the body between the fuel pump and the adapter....

Woah! The fuse is there to protect the electronics, a bigger fuse will let more current run through a possibly already-damaged circuit, and if it isn't damaged, it could be taking more current that its designed to.

However, I have no experience in automotive wiring so someone correct me if I'm wrong.

[87e30]

I just don't see where the hell there could be a short. I didn't touch any of the wiring in these areas. And the fuel pump etc is working if the car is running...

Are there wiring diagrams of where exactly the wires for fuse number 9 are at and I could trace all of those wires individually.

The harness has every single connection taped of and then the entire thing taped. I checked quickly without taking each single connection off so it was hard to really say but it looked okay.

[87e30]

Hey, how does the fuse box connect to the power?

The fuse box has two power wires come off of it, with different size connections. I have both of these connected to the main power wire. (biggest one) I just switched it and connected one of those to the smaller power wire. Teh fuse still pops.

I'm wondering the proper way to connect the fuse box up to the battery for power.


(drove the car aroudn today, it backfired slightly but overall ran pretty well for no rear o2s and no exhaust, I think once the fuse issue is figured out and exhaust is on she should be doing well!)
