Yesterday, I pulled the fuel pump relay apart and cleaned the contacts. I know, "just buy a new one" well, I can't get one this weekend. First try this morning and it fired right up but as we both know, it might just be in a "good mood". Will see how it does this week.

If the relay fixes the problem on my car, I'll post something.

Here's a short list of other possibilities:

- Idle control valve sticking. You can clean it with some carb cleaner.

- Flaky thermo-time switch (replace mine, no better)

- Flaky cold start valve (next on the list)

- Poor ground connections, (and power connections at the battery). Make sure the connections are all clean. If you have a voltmeter, you can look for voltage drops along some of the cables.

- Sounds like you already looked at residual fuel pressure. I also added a check valve in the fuel line, no improvement!

I'm sure there are more things to look at, good luck.

Ok I'm stumped. Spark; yes. Gas; yes. Starts every time I don't need to go anywhere. When I need to go somewhere it wont. Seems to be more prevalent during hot weather. Eliminated vapor lock possibility by installing a check valve between filter and engine near pump. Checks when hot and pressure is definitely good. Checked wiring to all ECU sensors and looks good. Got it running and disconnected sensors one at a time and each one caused a change in running. I haven't done reference/speed sensor yet. Anyone know a way to test them? My family believes that it just wants to mess with my mind. I am tending to think that also. Electrical manual being delivered on Monday. Any suggestions would be appreciated.
