Newbie here with a couple of problems.

Post by Lesley »

Hi all!
I just bought a 96 V6 5speed, with 199,000 kms on the odo. The car sat for close to a year. I've just had the water pump, timing belt done and a broken motor mount replaced. Tonight was the first time I've actually had it out driving - just got the plates on it today. It ran great, made a few stops, washed it, put gas in it, no problems. Stopped at Crappy Tire to pick up some things.. it wouldn't turn over. Kept trying... the wierdest thing happened. Tach shot all the way up past the redline - where it stuck!!! Even with the car turned off, the needle stayed there.
I let it sit for half an hour, tried again, with the needle staying in the red, not moving. Check engine light was on, still, car would not turn over. Needle suddenly jumped back down where it belonged, car turned over and started, but ran badly. Stalled in traffic, had to push it to a gas station. Started again, got it home. Check engine light is on. Any ideas from you guys who are familiar with these cars? It sat for quite a while, so I'm picking up stuff to tune it up (man, it's hard to find plugs and wires for the 96 V6!!!) as well as new filters.
Any advice/help is much appreciated!!!

96 model would be obd2 - you might need a code reader/scan tool to read the engine codes - if you have stores like autozone, advanced auto etc in your area they might read the engine codes for free. You probably need a 96 service manual to lookup what that code actually means.

But since you mention tach problems and not turning over - it could be the distributor which is a common problem with v6 engines i hear. The v6 experts here may have much deeper insight ....

Well, we tried the OBD II scan tool, it just came up error. It's also missing while idling. Could the distributor cause a CEL? Could it be a sensor?

thanks for your help! :)

Dont know much about v6 or obd2 - there is a diagnostic routine for pre 96 vehicles - http://eunos30x.com/info/CEL%20Codes%20 ... mplete.pdf - you can try that just in case your car is not obd2. Your problems sound like either bad timing belt or bad distributor - but i think timing belt problems wont make the tach go crazy though. You can try getting a replacement disty from a junkyard just to see if your disty is the problem. Also I think you have to re-time the engine if you change disty.

You might get much better answers if you post this in the v6 forum.

Hey guys - had a friend with a Japanese code reader come over, here are the codes we pulled:
P-1345 - No CMP or SGC signal.

Anyone know what that means?

thanks for your help :)

OK, I think I know what they mean - cam or crankshaft position sensor??
Been sifting through a lot of older posts to see if I can figure out what to do. Is the sensor located on the distributor? (please tell me it's not in the engine :( )
I'm thinking the tach is an entirely unrelated problem, maybe a bad electrical connection?

cam position sensor is integrated with the distributor - the tach gets the signal from the ignition coil which is also in the distributor. The electronic ignitor module is also inside the distributor - If you consult the service manual http://www.mx-3.com/95manual/index.cfm you can probably see all that (although its for 95 models)- and if you search the v6 forum you will see that its a common problem and what people have done to fix it. Replacement distributor and/or HEI upgrade will be the way to go i think.
