Creamsicle Project, Still tinkering... now it's running! Options

[poorsche914]

I finally decided to tackle getting my LE started and thought the long Labor Day weekend would be the perfect time. I had already replaced the fuel tank and lines up front and had sourced '74 FI parts and bought a new Optima battery. The final piece to the puzzle was a working fuel pump which I got a couple weeks ago.

So this weekend I installed the pump and put power to it. It ran but wasn't pumping fuel up to the engine. I heard gurgling from the tank. Low fuel level. So I added more gas and tried again. Success! Fuel was now being pumped to the fuel rail but there were several leaks. Took care of these and cranked it. Nothing. Pulled two injectors and saw they were not firing. Swapped out harnesses and more of the same. (IMG:style_emoticons/default/sad.gif)

I have both a single progressive and dual 40s. I seriously contemplated pulling the FI and installing the single Weber after a rebuild just to get the car running. After chatting with mipstein I had a few things I thought I should try first. I put power to each injector and they all fired so that took bad injectors out of the equation. I looked over pbanders d-jet page for clues. Somewhere along the way I realized the ECU was not getting power and perhaps the relay board was suspect. Having two extra boards, I picked one, transferred relays, etc and plugged it into the 914's harnesses. Turned the key, let fuel pressure build, cranked it and she fired right up!!! (IMG:style_emoticons/default/mueba.gif)

Vacuum lines, etc aren't hooked up so it revved high before I turned it off. Next step is to hook up all the vac lines (and install new shift bushings, install accel pedal, etc, etc) Goal is to have it on the road for MUSR11 (IMG:style_emoticons/default/driving.gif)

Got a vacuum line kit from AA and installed it last night. Hooked everything up according to the schematic which was very helpful.
Turned the key and it would turn over but not fire. (IMG:style_emoticons/default/dry.gif)
Pump runs for several seconds and then turns off so apparently system is getting pressurized.

Today I tried some starting fluid to see if that would help. Nothing.
Unhooked the advance and plugged the nipple on the throttle body.
Pulled a plug wire and inserted a spare plug to check for fire. Had my son turn the key.
It fired right up (IMG:style_emoticons/default/blink.gif)
Since I was holding a plug wire, I told him to turn it off. Ran about 5 seconds or so.
Replaced plug wire and tried to start it.
Started to fire and then BOOOOOM and a cloud of white smoke out the tail pipe.

Now, it won't crank. The starter just clicks. (IMG:style_emoticons/default/confused24.gif)

Any ideas? Not sure how the BOOM would be related to the starter not working. The motor is not locked up.

is it a click or more like a clunk sounds? Same thing happened to me and Idk if my motor is seized up or not. Right now Im stuck on this.. Figuring out the problem isnt easy! what is a BFH treatment for the starter?

For me, it was a click at the starter. I removed the starter and gave it the BFH treatment which is banging on it with a hammer. Whatever was stuck came unstuck and it has been working ever since. (IMG:style_emoticons/default/confused24.gif)

As far as my electrical issue - hooked up the center console gauges and none of them work. Well, except for the clock (IMG:style_emoticons/default/blink.gif)
Any idea what one main thing might be keeping all the gauges and blinkers and dash lights from working? As an added note, the hazard lights work but does not show on the indicator on the tach.

Did you ever try to push start your car before you gave it the BFH treatment?

No, never tried that since there was a car parked in front of the 914.

After mulling this over and searching the forums for hints, (IMG:style_emoticons/default/head_hurts_kr.gif) I still don't know why the gauges, wipers, turn signals, etc do not work.
The car starts and runs but the gauges do not work (IMG:style_emoticons/default/hissyfit.gif)
Hazard switch works but the indicator on the tach does not blink.
The turn signals do not work. The wipers do not work. The A/C fan does not work. The fuel gauge & low fuel light do not work.
These all worked when I first put a battery in the car a few months ago.
For a period of time recently, I noticed when I activated the turn signals, they only caused a bzzzzz noise and no indicator light.
I have not messed with the wiring beyond replacing the FI harness and the relay board. Swapped out four different boards.

Could the ignition switch be faulty?

Thanks for any suggestions, etc.

It could be the ignition switch but then you don't want to start changing parts without testing them.

Electrical problems can be cured many times by cleaning the contacts on the fuses, checking, cleaning and tightening the ground points.

The number of times you will have electrical problems is somewhat proportional to how long you own your 914.

I suggest buying a volt-ohm-meter. You will need it over and over again with your 914.

There have been times with my 914 and my 911 where I carried my volt meter with me while diagnosing intermittent problems.

For us to help you, many times we will need to check voltages or resistance at different places.

You can find them at Home Depot, Radio Shack, Frys, any electrical supply store for anywhere from $10 to $200+. $25 to $50 will buy you a usable VOM.

Buy one or borrow one and you can start checking voltages in different places. It's a lot easier than guessing.
