Re: Exploere EGR
This is getting stranger and stranger.
As mentioned earlier, I did hear the noise in the engine compartment for a few seconds when the key was turned on. I don't know what makes this, with the pump in the tank, but it did.
As in past tense, now nothing. OK, I pressed on the needle valve that is conveniently located up top and absolutely nothing came out of it. Alright, that makes it a little easier. No pump noise, no fuel in the line, ok. So why pump noise and then none? Pump was apparently running after the vehicle died, odd that it would happen now.
I figured maybe the filter was clogged, so I replaced that. I still get no pump noise and after a good 30 seconds of cranking no fuel from the needle valve. I opened up the tank side of the fuel filter and didn't get splashed.
Checked inertia switch, seemingly ok there. I pulled the connector off the switch and with the key turned on I get no power on the green/yellow wire. When I initially started all this mess I did have power at the switch.
To the relays - pulled out the fuel pump relay (checked the book twice to be sure I had the right one), measure 12V across the coil terminals for a few seconds when the key is turned on. So power to the relay coil is ok. (yes, I tried another relay).
I jumpered power to the NO contact terminal running to the inertia switch, according to the schematic, and still have nothing at the inertia switch! What are the chances of there being two separate problems?????
My next step is to hard wire power to the inertia switch connector to see if I can at least get the pump to run. That way I can see if the engine at least starts. Then there is the power to the inertia switch matter. While checking, I found the NO contact terminal goes through 2.7kohm to ground. I guess that is the PCM.
