No Start

Was sitting idling tonight waiting for my daughter and my 94 D90 just died.
No stumble or sputter...just shut off.

Tried turning over a bunch and it finally turned over and ran for 10 second.

Opened the gas cap.
Added fuel
Replaced Silver relays
Generally stared under the hood in confusion

Still does not start.

Over the past month is has been exhibiting the following symptoms:
"smells" like it is running rich
dying at idle (but would restart)

Any troubleshooting tips?

Just went and spent a few minutes looking into this:

No spark at the lead from the coil to the distributor cap.

Still the ignition amplifier? Anyone have a link the the replacement procedure?

Now it gets interesting....

Didn't have time to fix so I called a tow.

Decided to try an fire it up instead of pushing it out of the garage....and it runs GREAT.

Tried starting it 10-15 times over the weekend...and now it randomly started.

Ran it for 45 min in the driveway to see if it failed on heating up...running like a champ.

Any ideas? Totally confused now...because if I bring it in...they will have a hard time diagnosing...

I did remove the connectors from the Ignition Amp and wiggled some stuff...

Dave

I try to expand later when I'm not typing from the phone, but mine was a very similar experience with my ignition amplifier module. It got so bad to the point like you describe above where it would barely start or run at times...but at other times it would. I was in a time crunch, and bummed a used module from Galpin and threw it in at Huffs since he had a timing light (you can do it carefully without messing with the timing, but we were leaving on a wheeling trip and I didn't want to risk screwing it up).

Anyhow that instantly solved the problems. However, it's been probably been a year or so and every once in a blue moon I have a similar issue - today being one of those where it started to be down on power, over fuel, and start knocking. In cases like this a simple shut off / turn on does not work...I actually have to use my kill switch (which disconnects the battery) and then it fires right up. I presume that the kill switch resets the ECU or something.

Anyhow, I have the ignition amp relo kit from AB and plan to put that in ASAP. If it were me in your situation, I'd probably spring the $150 for the kit (which includes a new module...by itself that runs $75-80). It's worth a shot, and bottom line is they make these kits for a reason - it's a known issue, so even if it ends up not being your issue I think it's a worthy upgrade anyhow.

One thing you may want to try in the interim is disconnect your battery to see if it resets the ECU and will allow you to start. But if the module is shot it may not matter.

Just an update on this. It WAS the ignition amp and put in the relocation kit...not issues for the last year!
