I have developed a problem with my 85 GL. It has 195k miles with new head at 125K and normal maintenance. Lately there are times when I must crank the engine for 10-15 seconds or more before it will start. The longer times seem to be when I try to start it after say a 15 minute shutdown. Cold, it usually starts is a second or two of cranking. It runs fine otherwise. My mechanics worked for a week trying to identify the cause without success. They did find other things that need fixing. What I know at this time is: Not the O2 sensor - replaced Not the fuel pump, filter, pressure regulator - replaced Not air leaks - replaced intake boot and a few hoses Not the timing or distributor - check, cleaned and adjusted Have never replaced the computer or the air flow meter Stepping on the throttle (air inlet) does not make a difference On one occasion it stopped at a traffic light and did not start for a good 4 minutes of cranking. During the starting phase the engine is either not getting enough air, spark or gas at the right time. I don't think it is the spark. Do any of you Vanagon wizards have any ideas where to look next?
