Yesterday I thought I'd take a look at the one remaining issue with my car's running, the cold start up. I have to crank it for about 5-6 seconds before it'll start, and then I have to keep the throttle up with my foot for maybe 30 seconds before it will idle. I can drive it without a problem as long as I don't let the engine try to idle by itself. After a minute or so, it's ok.
It was in the low 70's yesterday, I pulled the cold start vale and watched it's operation as I cranked the cold engine. No fuel came out. Checked voltage at the harness, no voltage. Triggered the CSV with a 9v battery, it clicked open and spritzed some fuel. I've located a couple wiring sources, but before I go crazy with that, should the CSV even be open at that temperature? I've read that Thermo Time switches rarely fail, and I've checked the AAR, which closes (coincidentally (IMG:style_emoticons/default/blink.gif) ) around the same amount of time it takes for the car to idle by itself. I've also blocked off the hoses to the AAR, and see no difference. 2056 with 9550 cam. Car runs great once I get past this hiccup. Any ideas? (IMG:style_emoticons/default/confused24.gif) |
