Replying to: theelectrician (Jul 09, 2009 10:06 am) Check your connector under the dash for a burned contact or a contact that has unclipped and is recessed too far to make contact. I am assuming your car is wired like an 03 leSabre. I checked the CJ2 diagram for auto temp control. fuse #37 goes to the control, but you said the control is working other parts of the system. On the blower motor connectors B and C are power and ground. A is a feedback to the control unit. You might use a fused jumper to see if you can apply power to the old motor and make it turn and then the new one. Good lluck. |

Replying to: shawn101g (Jul 13, 2009 4:56 pm) You may have a connection problem in the various battery cables and grounds. Especially grounds. Do you hear a click when you turn the key to ON as the starter tries to work? There also are ground busses under the door sill plastic liner and carpet on the driver's side and passenger side. Pull out the sill at the front and check for corrosion on those grounds. I do not know if one affects the starting circuit, but cars in wet climates or having leaks have developed corrosion there. The chip in the ignition key is read by contacts in the lock cylinder. Two tiny thin wires go down the column, inside a plastic cover that looks like it's a solid wire itself, to the connector at the bottom of the column where the two inner wires split out to different connections. From there the leads go to the computer on those early years of PassKey and the resistance is read by the powertrain computer whether to allow injector pulses and to allow the relay for the starter circuit (high up on the firewall above the passenger's side where it's very hard to reach. The two wire can be cut where they go up to the steering column and connector by a resistor series of the same resistance as the chips in the keys. Then the computer gets the right reading for the car's key all the time. No theft resistance. http://vats.likeabigdog.com/ http://www.thirdgen.org/vats_passkey_system

Replying to: jmose (Aug 23, 2009 5:41 pm) for OBDII the P0629 is Fuel Pump A control circuit high voltage... You may have OBD I but I believe 94 and 95 have OBDII codes but OBDI type connections. http://www.fullsizechevy.com/forums/general-discussion/technical-maintenance/361- 333-gm-diagnostic-trouble-codes.html http://westers_garage.eidnet.org/obd2.doc. |

car starts runs 2-3 sec stalls. yes it has obd ll j1962 plug for diagnostic. new fuel pump, filter . I was trying to find code definition for p0629, pass key resistence is 524 looks to be in range

Replying to: jmose (Aug 23, 2009 6:20 pm) How was the P0962 determined? Were proper cables and reader that can do the odd 1.5 OBD setup GM had? Your problem is NOT VATS so the key resistor chip is not in play here. Who installed new fuel pump? Was it doing this before the pump was replaced? There may have been another problem rather than the pump itself. It is important to diagnose before replacing parts. |
