Swaps, Turbos, Buildups / Metric Mechanic Forced Induction motor

« on: July 08, 2008, 10:09:38 AM »

Hey P. Kennedy,

Bruce is actually my dad, I just thought the E30 enthusiasts online would like to see this project.

Any specific questions I can help you with or answer?

The car is currently shutting off at 60deg. centigrade, so we sent the Link 2.5bar MAP sensor & G2 Engine Management system out to California to get tested, so we are waiting to hear back.

Thanks for the compliments, and the car made 267whp@13psi on a Mustang dyno.

Next up, Water Injection!

Electrical / Fuel Pump and Main Relay issues...

Well apparently I must be deaf (couldn't hear the fuel pump turn on), because I just replaced the Crank Position Sensor and the car fired right up.

Guess it was a good thing I didn't have to go chasing electrical gremlins.

Thanks again guys.

A bad crank sensor will not allow the vehicle to start at all - you can turn the engine over, but it would never start, it will just keep "cranking".   I had this happen on my prior E36 M3 - bad crank sensor.  The car died when driving home from work one day, just turned off w/o any warning (that was fun).  I got the codes by doing the gas pedal trick while waiting for the flat bed service and that's what it was, faulty crank positioning sensor...  After ordering and installing the new, it started right up.  If I remember though, the fuel pump will still turn on and prime when just turning on the key...  So, I don't think a faulty crank sensor will prevent the fuel pump from priming...

?

Did the prior owner screw around with the wiring harnesses - meaning, did he cut any wires or can you visibly see any damages to any of the engine/dash/fuel pump harnesses?  Do you have any blown fuses?

Not that I can see, or know of. The engine wiring harness has been untouched as far as I can see, the only addition to the electronics is the Aftermarket Keyless Entry/Alarm, but that was when the car was in the early 90's.

Put your meter on the pins of the crank sensor .You should have around 650 ohms.
If you don't get a reading then it is faulty and should be replaced.

Yeah, I didn't get a reading on the crank sensor at all, so I have one coming from the dealer today. But I think there is more to the problem.

Well, I yanked some from my DD '89 325i, so I'm sure they are the same.

Also did the DME diagnostic thing. Got a 1444 Code, even though I'm almost positive the crank sensor is bad. Hopefully I can figure this out.

Thanks guys.

So, putting everything aside - you do have the new fuel pump installed, correct?  If so, when you turn the key "on", do you hear the fuel pump prime at all?  Almost every EFI vehicle, as soon as the key is turned on (KOEO), the EFI fuel pump should immediately prime (you should hear a distinct short "whine").  Are you hearing the fnew uel pump prime at all?

Prior to purchasing the vehicle, did you hear it start up and run - or did it not run or start when you purchased it?  If it was running when purchased, what symptoms were you experiencing that pointed to a fuel pump replacement?  Did you get or pull any codes from the DME prior to replacing the pump?

Yes, the new fuel pump is installed. No, when I turn the key to "on", i do not hear a whine, or prime. What I was saying earlier is that if I jump #30 and #87 on the fuel pump relay, it turns on no problem. Yet when I put in a known good relay, and check for power at the fuel pump, I don't have any.


No, I bought the vehicle non-running assuming it needed a fuel pump. P.O. did a few things like change the alternator, belts, and is actually a member of this site and others (Majikal). How do I pull codes from the DME? Diagnostic port in the engine compartment? And can I pull them even if the engine doesn't run?

Thanks for the detailed reply.

Have a spare DME? If you have good power at 30 and 86 on the main relay, and good power at 30 at the fuel pump relay, I would hazard a guess that the DME is possibly at fault.

I do have a spare 175, but I'm not sure if it is good or not. I'm assuming that power should not be flowing through those wires when the ignition is off.

Also, just checked the resistance of the Crank Position Sensor and I don't even get a reading. Cam Position Sensor reads 1250, so I know the multimeter isn't faulty. Could this be an issue as well?

Can't find it on realoem. Anyone know what it is and where a good place to buy from (BMA, BavAuto, Dealer, etc.)?

Thanks,
Ben

Well, I've been having trouble getting my newly acquired 318i started, so I thought I might what you guys think.

I just replaced the fuel pump, since the P.O. said the one in the car was bad. However, I couldn't get the fuel pump to turn on through the relay.

Jumped the Fuel pump relay at Connectors #30 and #87 and heard it turn on. Threw in a known good relay, and the pump will still not turn on.

This morning I pulled the main relay and fuel pump relay off, and tested them with a 12V test light w/ the ignition off. Apparently there is power going to #30 on the Fuel Pump Relay, and #30 and #86 on the Main Relay. WTF?

I don't want to start tearing the harness apart, but I noticed all of these power go to the Battery Junction Block (See page 1360-1 Injection Electronics on the Troubleshooting manual).

Anyone else have an issue like this? Thanks for any advice/input/suggestions.

Ben

Ever figure out what was wrong? I'm having the exact same problem right now, and wondering what you replaced....

wow, nice job man, i wish i could do the same but not everyone is rich... any idea about numbers>>> and what engine management>?>>??
keep us posted

See my original post for engine management, very similar to Autronic, but slightly easier to tune - http://www.linkecu.com/

I wish I was rich too. Isn't my car even though I did contribute in other ways.

Thanks for the compliments!

Glad to see you here!

Can't wait to see it complete

Thanks man!

It shouldn't be too long. The shop that is doing to wiring still has a few things to finish up. We shall see.

Hi all.

I post over on r3vlimted along with mye28 and 2002faq, so I see some of the same E30 guys that are on r3v. I daily drive an E28 535i, and my dad and I have quite a few BMW's. So I just want to post some pictures up of my dad's car that I have helped him build (he financed it) and just tell you guys a bit about the car.

It's a 1991 318is Diamonschwarz over Black Vinyl. It has 178K miles when we got it with the blown motor (timing chain went).

Anyways, it has gotten quite a lot of money, time, and parts put into in the last 8-9 months and still isn't ready yet.

Engine & Drivetrain:

Metric Mechanic 2000 FI Engine, 8.5:1 Compression, Different Intake Cam,etc.
666Fab Tubular Exhaust Manifold
666Fab Downpipe
666Fab Sheetmetal Intake Manifold
666Fab Custom Water/Air Intercooler
A bigass Garrett Turbo
Link Engine Management
ZF 5-speed Transmission (out of an E46 328i)
M5 240mm Clutch
Single Mass Flywheel
Shortened Driveshaft
3.25LSD (from an 85 535i)

Suspension:

E36 Z3 M 5-Lug Conversion (Brakes, Trailing Arms, etc.)
E30 M3 Aluminum Control Arms
GC Coilovers with Adjustable Camber Plates
Koni SA Adjustable Shocks
(theres more, I just can't think off the top of my head)

Ok, here are some pictures I randomly selected:



















Here's a link for the original build - http://www.r3vlimited.com/board/showthread.php?t=84137

Sorry for such a long post, just thought you guys might want to see this.

If you have any questions, comments, etc. I'd be happy and try to answer them for you.
