Well I have had my car kinda running for 1 day now. I have been able to drive it up the street The car will stay going with no problems.. Then I will shut the car off and try to start it again. It turns over just fine but I can't get any pluse from the injectors. So I let the car sit for a few hours then it works fine I can even start it on the frist crank. Can someone help me trouble shoot this thanks. (IMG:style_emoticons/default/wavey.gif)

Since others are doing it, I must chime in.....
How do you know that you aren't getting the pulses? Have you checked with a NOID light? I would agree with Gint, it sounds more like a fuel delivery problem. You should make sure you have good fuel pressure before you jump to too many conclusions. If you really aren't getting the pulses, it is one of a few things causing it: A. Bad Trigger points. B. Bad wiring / coroded terminals C. Bad ECU (least likely) My guess: Bad ground connecton on top of engine case (fuel injection) causing high resistance when hot/warm preventing trigger points from "triggering". Also causing a whole host of other problems. My recommendation: 1. Go to a car parts store and buy a can of spray contact cleaner (CRC makes a good one) or Radio Shack sells some sort of spray contact cleaner. (You could also use some very fine sandpaper to clean each terminal) 2. On your fuel injection harness...One at a time, pull a connector noting how it plugs back in, and spray both the connector and the plug with the contact cleaner and plug it back in. 3. Take your time and be sure to do each one. Some are harder to reach (like the grounds on the top of the engine case (near the transmission bell housing). Be patient and make sure they are clean. It can take a while so don't be hasty. 4. Try it out again. Good Luck |
