it started as the car saying the door was open when it wasnt now the lights constantly stay on
The light comes on briefly then goes away. Could this be my oil pump?
OBDII inspection failed.catalyst not ready; evap. system not ready; O2 sensor not ready; ...............Not supported (items): heated cat., sec.air, A/C system, EGR. All other OBDII items show Ready. I recently replaced the battery and the alternator checks good. No check engine lights. I drove 30 miles at 6- to 70 mph and O2 Sensor shows Ready now.
at first just the speddometer stopped now the whole dashboard does the same things. while driving fuel goes from empty to full and back and forth. speedometer goes crazy and it goes from cold to hot and when bells go ding it stops and goes back to cold. is this a wiring problem on the dash. had this to 3 mechanics and no one knows what to do.
I have replaced the damper 11 times during the life of the car.I can drive on new mounts for about 2 or 3 months
2.0 liter SOHC, first generation vin designation 'C'.
After new valves, timing belt, (cylinder head removed). When initial attempt to start, engine cranked over - but no electrical on dash, traced that problem to the BODY not being grounded, could find no cables, straps, or wires that were disconected, so I fabricated a ground cable going from engine to cylinder head. Sha-Zam electrics now present. Attempted to start - no start - traced problem to having no spark at plugs, or coil.

Did 'flashing light' test at coil pack connection. Then replaced CPS (camshaft position sensor), then the CRPS (crankshaft position sensor) In that order.

Again this is ((AN ELECTRICAL PROBLEM)).

I am wondering if attempting to start for a time with the body not grounded could have damaged the PCM? (as it is bolted to the body) Remember the starter was working fine, even though nothing else electrical (lights, and dash indicators) would work) I really would not like to replace the PCM $$$$ if not the soulution.

All relays were switched around - NOT the problem - all fuses checked, one other thing, when we were cranking it over last week, I noticed some smoke coming from the rear of engine compartment - the exhaust side-.

Does the PCM have to be reset, every time I replace a component (CPS, CRPS)?? there are no trouble codes when testing with my OBD I, or II.

Please read this question carefully, before answering.

Any and all help would be greatly appreciated, as this is my daughters only car, and I am just trying to get it back on the road.

Thank You

i hit a bump and at first just my speedometer would stop working,now all gauges stop
Auto Trans on floor.
When it's been drove for awhile it clacks a little more than usual. sometimes it don't clack at all. Fresh oil turns back rather quickly. Neon website said it might be "piston slap". Never heard of that before. Doesn't show up on a code reader, and another Neon owner said he's had three Neons, and two clacked just like mine. It still has plenty of power and goes like hell, but make a ..... clack noise. any ideas?
my check engine llight came on for about a week then turned off for a few more days now its back on again.
Shifter keeps popping out of drive and the car only has 74000 miles on it
Timming belt broke when my wife was on the freeway I changed the belt but it acts like its not getting compression. it has spark and full. I suspect all the vales are bent how do i check to see if they are?
i took it apart three times to make sure the timming was right so i am 99% sure it is car was running befor timming belt broke.
brake light switch fell out not sure if wires are out or where to put it
I only know what my altenator looks like. I have basic mechanic skills and was wondering how i could go about changing it myself with a step by step guide or detailed picture with it showing a step by step way. Or maybe if someone could give info on a site that would have what im looking for. Thanks a bunch!! -college student with a broke down car
