my guess.it the radio pass word is lost.? right?if radio is stock, only the dealer can fix this. ask them and take reg. and photo id.

An actuator cotrols the selector of your hvac. (Defrost, floor, mix, etc..) usualy pneuamaticaly. If it becomes stuck in one position, or has lost pneamatic pressure or vaccum, it will not change or select other setting of hvac controls.

Hi: If you haven't changed your fuel filter in awhile, an easy way to check to see if your engine is getting fuel from the fuel pump is to replace the fuel filter. When you install the new fuel filter, leave the connection that goes to the engine off, and have someone help you: Turn on the ignition while making sure the outlet of the fuel filter is going into some sort of container. You should have fuel pressure of some sort. If not, troubleshoot the fuel pump circuit. There is a fuse and a relay involved. If you don't want to mess with the fuel filter, you can purchase a fuel pressure tester for less than $30, and it connects to a threaded fitting on your fuel rail.

You did not say what the problem is. Reset usually means the onboard computer and you can do it yourself by disconnecting the positive battery terminal (+) and letting it sit for about 10 minutes before hooking it up again.

ok slow down, it stalls, that is all we need, no need guess.and tune up don, but you skipped the fuel filter? and air filter,?STALLS 101.1: lost 12vdc to EFI system. lost elect. power. easy to test , easy to see. you can attach a DMM set to 12v at the IGN output wire.and see if it drops to zero as engine dies. sure can.2: you could , check for spark at death, got sparkand work that path if spark fails. 3: lost fueling, (sparks soaked in fuel x 4? ) then its floodingif dry spark tips x4 then lost fueling , so try test fuel.you failed to say, is this a hard fail , i t dont run now.or is always random... just a lil hint.assuming power is hot at all EFI fuses. then fails only 3 ways,1: lost compression hot (if solid lifters, lash never set)2: lost spark'3: lost fuel or flooding.if flooding use WOT, in this super secret mode works, Wide open throttle cranking, clears floods. (ecu cuts all fuel in this mode)

wow , rare here, no one every thanks great posts. and you are welcome

lost the operators guide? from glove box?

Now we are getting somewhere!! Check for power to your distributor. If you have it chances are your ignition coil is faulty.

its built into the main relay located at the drivers side kick panel , most of them are grey

Pull the central plug,Using a screwdriver ceck the spark by holding it inside the plug and close to a grounded part.Put some one else to start/crank by key.It should appear a short blue spark in between.Warning:Use gloves if u are amator,it can get to u :))Not bad if u are not ill,harmfull for heart condition.

It is providing a ground to allow the relay to operate.

The PGM Main relay is outboard of the glove box. You can see it if you get the glove box out of the way, but to remove it, you need to pop the triangular shaped plastic trim off of the end of the passenger side of your dash. The relay is held in place with one 10mm bolt and the electrical connector.

You should have close to 12 volts and then it drops to 0. That is the ecu priming the fuel system. Once you start yu should have 12v constant to the same wire. If your fuel pump is functioning ok, scan ur ecu for trouble codes. If there are no codes look into your coil and your icm in the distributor. Very commo for failure. Once the car dies, remove any spark plug wire on the plug side and put a plug into the end of it. Put the electrode of the plug close to a bolt on the valve cover and get someone to start the car, see if the plug is sparking. If it is you have a problem with fuel delivery, may not have injection pulse. You may also have a main relay failure

check out for fuel pump relay or loose contacts

bad motor. (gear box inside motor chassis)both wipers? if one bad, the shaft is stripped. at dead wiper.the motor can be a victim.if the linkage jamps it can wreck the motor.

reclear code

Worn rings and/or valve guides - time for a re-build.

most cars, remove skins the bumper bolts.they are hidden by the skins, on most newer cars.or read the FSMor log into , alldata.com

moving only or parked.the ECU, does its best to prevent stalls, in fact it can raise theidle speed, to stop just that. this is ISC actions. idle speed controls.if the car love to stall, coming to a traffic light , this is usually the EGR sticking wide open. (it closes just before you stop)you can save the stall with a fast right footeasy? ISC stickingharder, EGR stickingimpossible. (lost fueling or lost spark or bad DC power to EFI)the FSM shows the 50k service to clean the EGR main valve.it must not be sticky. the isc is the same deal, they too can gum up. 1998 , easy.
