On Saturday we headed out for a short one-night camping trip. When we arrived at the campground about 90 miles northwest of Houston I stopped to register (nice Corps of Engineers' Park on Lake Somerville). When I got back in the bus it would turnover but not start. It seemed like the engine wasn't getting any fuel. I checked the fuel filter to make sure that it was indeed getting fuel - it was. I tried to start the coach from the rear, again it would crank but not fire. This is a 1992 Angola Conversion with an 8v92 with DDEC II (258K miles with about 50K on a full rebuild) and an HT 755 ATEC Allison.
With a little more trouble shooting, I noticed that when I turned the ignition key on that the CEL and SEL (Check Engine Light and Stop Engine Light) did not illuminate as normal when the key is turned to the on/run position (normally the CEL and SEL illuminiate for about three seconds and then go off). Howerver, the CTL (Check Tranmission Light) did illuminate with the key in the on postion which is not normal. I tried checking codes on the ATEC and DDEC but with no luck - no flashing lights on the dash board. I got on the phone to DFW Prevost to ask for some assitance. They walked me through a number of things over the next hour and a half to see if we could find the problem. I and they believed that it had something to do with the DDEC or ATEC. We checked power to breakers front and rear, power to relays and whether the relays were working. Everything checked out normal. They went to the shop to look at the wiring diagram and we did a little more troubleshooting until they finally said that it was likely the ECM.
To make a short story long, I finally called Coach-Net to ask for towing assitance since it appeared we weren't going to be driving the bus anywhere. Coach-Net (as usual) was very responsive and there was a tow truck at our aid within a couple of hours. By this time is was dark and they did not want to tow the bus at night. The driver took my keys and they towed the bus back to Houston on Sunday.
The bus is at Stewart and Stevenson and they have started work on it. I will let you know what they find. In the meantime, anyone on the board have any thoughts?
