[DML] Re: Starting problem at in-between temps



Mark,
I had a problem that sounds a lot like what you are experiencing. My car
would start fine in the morning and fine after it had been running for
awhile but when it sat out in the sun on a warm California day (usually in
the parking lot at work) it would not start. I would remove the plug from
the cold start valve (blue plug) and put the control pressure regulator plug
(gray plug) on to the cold start valve and it would start up. Essentially
this is force feeding fuel into what turned out to be a starved fuel system.
When I would put the plugs back on to their correct components it would fire
up. It worked every time. I finally figured out the problem, it was the RPM
relay going out. After replacing the relay the problem disappeared.
Hope this helps,
