Hello, I've fenished up the manual conversion on my 91 CD turbo a few days ago. Spent yesterday and today tweaking a few things to get it running right. It's been on a few trips around my neighborhood at this point, run for a total of about an hour. Was going pretty flawlessly until today. I was taking it out for a little drive again after installing a starter button. It drove for about 2-3 minutes and just cut out after coming to a stop. Now it just turns over and doesn't make any attempt to start. It was wierd because it had been driven yesterday and this morning for about 10-15 minutes each time, with absolutely no problems at all. I've checked some of the more obvious things, all fuses OK, Quarter tank of fuel. When I pulled the spark plugs I found that they were covered in carbon, so I put new ones in. No check engine light before starting. Once I try to start it, it comes on and stays on until I stop trying. Only odd thing I remember before this started is that the idle seemed to be pulsing a little. I'm really out of ideas at this point. I've got the negative lead off the battery so that it can reset the ecu, but I wouldn't think that could fix it. Also, can gas go "stale" inside of 3 months? If anyones got any suggestions I could definately use them. Thanks in advance.
