problem

01-31-2005

When trying to tune today, at WOT, the car went boom and killed on me. The rpm guage doesn't work on the safc or the guage cluster. The car will crank but does not spark. The T-belt is fine also unless it skipped. Could this be caused by the SAFC connection that goes to the computer coming out? Would this cause it not to start? I don't have time to look at it now because I work.
Thanks

Does the AFC have power at all? If not, the plug going in unclipped itself. Just open it up and plug it back in.

Please state the car this is on, 1g or 2g. I would check the CAS too, if the problem isn't something really simple.

it is a 2g gst and it seemed like the car was cutting in and out a littler bit. The rest of the SAFC has power. I reconnected one wire that needed to be fixed for the power, But I didn't have any time to check anymore.

It doesn't sound like the AFC has anything do with it.Do you have a multimeter? Check the CAS and the transistor.

Crank walk eating the crank sensor?

The crank tollerance was .009 when mike checked less than a month ago so it was walking but not walked yet. Bartons went to .030 and I thought it ate sensors at .020?

SAFC works fine except does not register rpm either. Code p203 popped earlier (#3 injector). There are no check engine codes present now. The prior one was cleared and did not come back on. Something happened, the gauges turned off and the car stalled while moving. Has oil, cranks fine. Timing belt is also on there. Haven't checked to see if it jumped though. The car still had an exhaust tone though while slowing down??? Haven't had a chance to check if out yet. Happened before work.

Wires seemed fine. Nothing needed to be reconnected. Something could have happened to the rpm wire though... Appeared fine and the wire it was tapped off it was still together. Possibly the CAS or something...

Sounds similar to what mine did when my ECU went out. I didn't get any sensor response on the afc or datalogger.

**scheides** · 01-31-2005

ecu. Did you do a proper install with the afc, or a blue-snappy-T install? If one thing or the other crossed, buh-bye!

Check the ecu for blackness.

john · 01-31-2005

No, I used the red tap splices. Has worked on the 3 other cars without a problem. I would guess that the ecu is fine but will probly be pulled in a couple of days for dsmlink if the car can get running. The car may have been wheel hopping a bit and knocked a connector loose. May check over tonight.

The car gets fuel but no spark. The ecu is out of the question so I need to figure out how to test the cas on a 95.

john · 01-31-2005

Could I just wire in a 1g cas? It seems easier than pulling the intake cam and checking it that way.

LightningGSX · 02-01-2005

I believe you can, but the pulses will be inverted.It would let you know if thats the problem though.I'm about 95% sure its your CAS or the CAS's wiring.The easiest thing to do would be to take a multimeter, set it to AC, put the positive lead on the RPM wire of the AFC(or the CAS wire), ground the negative lead and check for voltage during cranking.

slowbubblecar · 02-01-2005

We will try it after school today, Thanks

No voltage would mean that the CAS is not functioning right? All the testing is doing is checking for any voltage correct. Then I can use one of my gay voltage testers instead of getting a new battery for the miltimeter.

LightningGSX · 02-01-2005

You're checking for AC voltage though, so unless your gay voltage testers read AC, they won't work.

Yeah no voltage would mean the sensor is not functioning

john · 02-01-2005

Ok, I just got back from checking it. I couldn't read anything off the SAFC wire or the ECU plug. I then went under the hood, popped the connector and checked the wires. With the multimeter grounded on the battery, there was no sign of any voltage on any of the three pins. So it looks like the CAS is shot. Hopefully I can find the one I threw aside when throwing a 2g head on a 1g... Looks like it may be time to swap the t-belt, HG and get some ARPs. Fucking 2gs...

john · 02-01-2005

BTW, the multimeter setting it was tested on was AC 750 I believe.
