Father-in-law is looking at it now while I'm at work, and he thinks the studs are simply screwed in, reverse-threaded. He hasn't checked the ones on the tensioner itself since they're hard to reach, but he said he checked other similar studs on the engine block elsewhere. Ray of hope, possibly?

NateStraight

How catastrophically stupid would it be to grind the outside of the flange down enough to where the nut might fit?

NateStraight

2004, base, ~300K mis. Trying to pin down the source of an incessant oil leak, I came across a post saying to check the o-ring on the timing chain tensioner on the back of the engine block. There sure was a ton of oil around there, so I'm guessing that was the bulk of it. In installing the part back...

NateStraight

GGGGRRRAAAAAUUUURRRGGGGHHHHHH!!!! Some fool who owned the car before me must have installed an aftermarket alarm that they never told me about. In taking out the radio to get to the wiring harness to pass the new wire through from the ignition switch, I see a little electric box shoved up there... S...

NateStraight

Got it. It's the wire from the 4 pin on the ignition switch to the 12 pin on the IG3 connector; shorted across it with a clean wire and it starts just fine. I just got to get to that wire harness.

Thanks one and all.

NateStraight

Anyone have the full wiring schematic for that switch?

All I can find is that it has 5 pins, and that 1-3 is open, 2-3 is closed.

It seems 4 and 5 are probably somehow related to an ignition switch and speed sensor.

NateStraight

I'd like to be getting nothing if I put the voltmeter between the 4 pin on the ignition switch and the 12 or 11 pin on the IG3 connector and crank it, right? I'm reading anywhere from around 3v to around 5v.

NateStraight

I can't see easily where that junction connector would be, unless it's somewhere in the giant harness that goes behind the blower housing. Voltage is good through the ignition switch; I can't seem to get the same reading at pin 12 on connector IG3 that I get at the ignition, though. I get about 14.5...

NateStraight

Ah. Good catch. That'd be a bit tougher than my originally devised system... I wonder if there are any other switches that are linked to the P/N switch? I imagine actually starting up the car won't be a problem... unlikely I'll be sitting there with the key to "On" and shifting into D befo...

NateStraight

Any harm in just setting up a jerry-rigged "push to start" button that supplies 12v directly to the starter relay on its own or some such?

There's even a momentary switch right there by the relays, for the rear window glass which we never use; it's probably got a fuse, too.

NateStraight

Yep, we had jumped across the park/neutral switch, too... same story, no crank.

NateStraight

Just managed to get it going again; doing nothing except trying it a few more times after checking this last round of relays.

Not sure what else to do at this point except trace every wire in the system and check continuity through each stretch.

NateStraight

Yeah, I'm looking through the ECM diagram / info, and it seems it shouldn't matter... all of the connections are only inputs; and it's wired in parallel to the starting circuit, so any extra resistance there may or may not be in there should be ineffective, yes?

NateStraight

NVM: pulled and tested IG1 relay; it's fine. P/W relay was out, but that hardly seems relevant... regardless, swapped it with working relay from Fog.

NateStraight

Hot mama! Put a bare wire jumper between IG4 and IG5; car tried to crank as soon as I put the negative battery cable back on [weird; key was not in]. Didn't do anything with the jumper in with the key; BUT, after I removed the jumper, I gave it a few quick tries... first time it turned over three o...

NateStraight

Bypassed P/N Switch; still nothing. Are y'all sure the ECM is unrelated? Is there a diode or something that could have blown out when the car was jumped and is affecting only this part of the system? Something between the ignition and the starter relay is dropping my voltage from 12v to around 8v. A...

NateStraight

I took the old starter relay, removed the top cover, put alligator clips across pins 1 and 2, stuck it back in the fuse box and gave it 12v from a spare battery while the key was "on"... started without problem. Something preventing 12v from reaching the relay seems to be my problem; all I...

NateStraight

Starter checks out. Will clean it up before putting back on, but I'm running out of ideas. Bought a new negative terminal to replace the cruddy OEM term.

NateStraight

No problem driving it around at all, but after turning it back off and waiting for a couple hours to cool down, tried starting it again and got nothing once again. I think the starter had just enough in it this morning to give it one good go, but nothing now.

NateStraight

Ran it around the block; it is running a little rough, and idling lower than it normally does. I believe that's pretty typical after the ECU resets due to power loss (disconnecting battery long enough). It will "relearn" as you drive. Great. I've kept it idling for awhile now in the drive...

NateStraight

Ran it around the block; it is running a little rough, and idling lower than it normally does.

Of course, it has tended to idle incredibly high [up to 2000]; right now, sitting in the driveway, it's idling at around 800. Maybe a change for the better?

NateStraight

Hot mama! I checked continuity from IG4 to SR1; fine. Checked continuity from SR2 to Gr; fine. Put a bare wire jumper between IG4 and IG5; car tried to crank as soon as I put the negative battery cable back on [weird; key was not in]. Didn't do anything with the jumper in with the key; BUT, after I ...

NateStraight

A/T.

I'll definitely be checking the ignition circuitry today, thanks.

Probably also will bring the starter and other battery in to be checked.

NateStraight

That was with the relay out.

I'll try your suggestions tomorrow and report; I really can't afford the computer replace right now, so I'm trying to rule everything else out before shelling out money for something that may or may not be busted.

NateStraight

Current status: All electrical systems seem to function except starter; call will start by jumping directly to starter, and drives fine. Replaced starter relay and all blown fuses; starter relay will click 3 or 4 times when engaged, and turn over once only. Checked EFI relay which powers ECM. Fine. ...

NateStraight

I tried jumping across the entire ECM system by shorting between two connectors at a junction point that were indicated as an input / output to that loop of the system; did not seem to affect anything.

NateStraight

I get about 8.5v across the 1st and 2nd contacts of the starter relay when I try to turn the key.

NateStraight

In the "Inspect ECM" procedure described in the manual you linked to, I pass every test except fail to find 6V or more between STA and E1 when attempting to crank the engine [of course, the engine won't crank normally to begin with; does that matter for the test?]. Looking more like a blow...

NateStraight

Yeah, I pulled and replaced the Main fuse, the AM2 fuse, the Dome fuse, and the EFI fuse from that other thread. All were bad. The starter is the only thing electrical that is out as far as I can tell. I can hear a few clicks in various places in the dash when I try to start, and you hear the starte...

NateStraight

Great, thanks. Downloading now.

If I can jump the starter directly, could the solenoid still be bad?

Or is it likely that there's a short in the wire headed to the starter?

NateStraight

Sorry to res the thread. I have the same problems and cause described above: Nothing in dash, blown ALT, AM2, EFI, DOME fuses; resulting from reverse jump. However, upon replacing these, I still cannot get the car to start. I can jump across to the starter direct from battery and start, so I thought...

NateStraight

No, I don't have any schematics / wiring diagrams. That would be helpful. Have now got the car to start by connecting direct to battery. Ran current through starter relay and it would not stay engaged, so went and got a new one.... no help, same story as before. Does the engine control unit have any...

NateStraight

Ok, so wasn't thorough enough checking fuses. Checked all fuses described here [viewtopic.php?t=36087#p461658] but unlike the previous poster, I get no cranking or turn over whatsoever [although the car will now at least attempt it]. Starter relay? Starter? ?

NateStraight

Found: 100A Alternator fuse was busted; jumped across it, headlights come on but car still won't start. In fact, the lights won't even go out... even weirder.

NateStraight

Also: Have read security lockout of ignition switch may be at fault; but, this car has no security device as far as I know.

NateStraight

Is there another in-line main fuse not in either fuse compartment that may have blown?

NateStraight

Story: I left my key in the on position overnight. Stupid mistake #1. Stupid mistake #2 was attempting to jump it with reversed jumper cables. "Battery terminal protector" I sprayed to prevent some incessant corrosion turned negative terminal red; didn't even think to read the battery, jus...
