Wont start after warm up

[blue62]

I just tested pin position 86 again to be sure.
It is battery voltage with key on.
But the voltage drops out about 5 seconds after I switch the ignition off.
This is without starting the engine.
Just key on then key off.

Hey blue62

Well, thanks for letting me know...goodness knows Im confused enough with this thing...lol...at least now I know how the relays work...haha

Im going to keep going through things ( when its not pouring rain )...cleaning grounds etc..cluster grounds and ecu grounds first..CPS might still be the issue when warm...I wonder if that could have thrown the DME code...I do have a durametric but my laptop is a bit long in the tooth and a bit frustrating to use...might grab a new one this weekend

Cheers

Pouring rain....I am guessing your in Vancouver Wa.
I am up in Woodland...
Grounds, CPS, or the ignition switch....I know you replaced the ignition switch in the past. But it is a possibility.

Also if your CEL is not working you could have codes.
Then there are pending codes which don't set the CEL.

Up in Vancouver BC area...just north of the border

Ya, will be working on a few things today and may get out the durametric on the weekend...should have tackled this in the nice whether...lol

Thinking just to replace the cps, although I am not one to throw parts at a problem...however it won't throw a code from what I have read and they aren't that much for the peace of mind, and may cure the main issue

Might buy a fuel pressure gauge as well...will search for something decent

cheers

You could rig up a way to wire a Digital multi meter into the CPS wires.
Then run the engine tell it stalls.
Then try to start the engine and watch the meter for a CPS signal.
I think they give off a hertz range signal but not positive.

Goggle testing CPS I'm sure you will find lots of info.

I thought you may be down here in Vancouver wa.
Every time you mention rain it is raining here in Woodland just North of Vancouver.

So it stalled again,...I bypassed the fuel pump relay and it started...but when I test the relay out of circuit it works fine on the bench...thinking the relay is intermittent...and not working with a load on it

cheers
