Dashboard lights stay on all the time

[alex7542]

OK i figured u meant the igniton switch jsut wasnt sure what connector.when you say i can just change the elecrtrical part. Do you mean the wires or what. Because the link you sent me to is ingnition switch.

[NISTECH]

yes that may be the whole lock cyl judging by the price. not sure. but you can just rplace the black or brown disc on the back of it the wires are attached to and leave the key portion of it on the coloum. it would be just the electrical portion.

[alex7542]

oh ok. when i get the car home tom. Ill take it all apart and see whats going on. maybe theres a loos wire or something. maybe its not completly broken. because the ingnition works perfect. except the thing of lights. I also got the coolant tank. i had to buy one from discount cause at the junkyad all 240s coolant tanks had a hole in them. Was that a recal or somethign they were all broken on the same part in the back top corner.

I have the same problem, the dash light stay on when i take my key out, ill check those ocnnectors

[alex7542]

HeyNistech this suxs man. I replaced the thermostate. and when i went to turn the car on it wouldnt turn on. i checked for spark and theres no spark. And i honestly dont know wtf could have happened. Man this pisses me off so much. i thought i finally was going to be able to drive my car and never got to.

I was thinking that maybe when i tooked the thermostat of i pulled the radiator hose to hard and disconnected the crank angle sensor. But i looked for the sensor i really couldnt find it. Maybe u can tell me what too look for or what trouble shoots i can look for in no spark.thanks man AlexP.S. kyle when u figure out wussup wit ur lights id really appreciate it for you to tell me. Also does it kill ur battery quickly with the lights on or na.

[NISTECH]

did you ever disconnect the ignition connector? the crank pos sensor is in your distributor. make sure the dist. and coil connectors are all still connected.

[alex7542]

Hey nistechYea i did disconnect the wire that goes connected to the distributor. But i re connected it. What thing i did by mistake was i tried to start the car with the wire disconnected i noticed it was disconnected when it wouldnt start. So i went and connected it and nothing happened it didnt turn on. I didnt have a chance to check things out today and i wont be tom so friday i have to do the checks. Im going to check for voltage on the coil wire. to see if there is.But i honestly dont know what could be wrong.

[NISTECH]

I honestly cant think of what is causeing your no start from just replaceing the t-stat. I assume it cranks over but doesnt fire up. check and make sure no fuses are blown. also make sure the smaller wires on you positive battery cable are fully seated in their sockets. make sure your alt connections are ok. If its lost spark it has to be something you moved or did since the last time you had it running. if you did any wire checks under the dash go through and make sure you got them reconnected.

[alex7542]

Ok yea it does crank. We checked the fuses the big ones the green ones and they were hot. like not normally a fuse isnt hot but these were. and i didnt touch any wires inside the car i havent gone into the car to touch wires. my friend did thouch the radio wires thoguh before i tried to crank it when i replaced the thermostat so maybe some wires are touchign each other or something. causeing a malfunction. My battery negative wire i havent screwed it in completly because ive been workign on the car. but thats how it has always been even when i started it. plus the car has power so i dont think that could have been a problem. Im goign to check the alternator wires tom and see if i can figure everythign out. I really need this car driving already and all this suxs but i guess those are the consequenzes of a 300 dollar car.

[alex7542]

Hey nistechThis is the up date. i rechecked my wire harness and everythign is connected. and i volt tested the coil wire and it does have current. but i volt tested the wire connected to the distributor and there was no power at all.MAybe you know where i can check thats causing it to not have powert. i seperated all the radio wires ad made sure it was not touching wires. So i cant seem to figure it out. I alos heat dried all the connecters incase they got wet with the thermostat change. and also checked everysingle fuse with the voltmeter and there all good.THnaksAlex

[NISTECH]

I need to look at a schematic to figure out your power and gnd routing to the dist. there are a few wires going to it which wire did you check for power and are you sure that was the power supply wire?

[alex7542]

hey nistechwe checked all the wires. and there was no power in any of them. what we did with the voltimeter is i connected the negative to the negative of the battery and tried every wire with the positive. and the voltimeter always showed 0. This is with the switch on. im not sure if were suppose to check it while trying to crank the motor. and my teacher hes a certified mechanic told me no. but he cant figure out our problem.

[NISTECH]

hes right you dont need to crank it to have power to the distributor. I wonder if your dash light problem is associated with this? your distributor harness runs across the front of the engine if I am not mistaken. did it by chance get wacked by the cooling fan when you tried to crank it with the connector disconnected?

[alex7542]

aa i dont know if the dash has anyhting to do wit it because the car was running before even with the dash bad. and i honestly dont think it got wacked. but anyhow i did check all the wires to see if it was broekn some where withing the harness and i didnt find anything. i even took the black cover that covers most wires that go on top of the injectors but i couldnt see much to many dam wires. any how i dont think it was broken. at least i didnt see anything. and when i had taken it off it was hanigng down to the bottom. wit enough space between the fan and wire for it not to hit.

[NISTECH]

do you have a wiring diag for the engine control components?

[alex7542]

naw i dont. but i can get one threw mitchell1 which is like all data but supposbly better. we have that at school. Now that you mentioned it i will remmeber to print out all wirieing diagrams for the motor and dash. i knwo you gave me the dash so actually jsut motor

[NISTECH]

yea you want the schematic with the dist and coil in it. you want to trace the wire for power and see if the source is there.

[alex7542]

yea. well i was thinking of removing the ecu and supposbly on the ecu theres 2 ligths to check for codes. so maybe im going to run a diognastics like that and see if a code comes up. i knwo the egr code will come out but not sure wut else/(i took the egr out)

[alex7542]

HEy nistechmaybe you can help me out. can you tell me were is the eccs relay located at. and the power transistor on my car. i have a feeling its one of those two that went bad causing my car to have no spark. BEcause i checked the coil for resisance and it does have and then i check the coil wireing and it has power.

i was looking at the wirediagrams of the car and it seems like the distributor is connected to a resistor and condenser and then the power transistor and the eccs relay. So maybe one of those three are bad. thanks

[NISTECH]

the eccs relay should be in the relay box under the hood. there should be a box just below your intake tube near the aircleaner assembly. the other I believe is on the passenger side of the engine compartment in plain veiw.

[NISTECH]

the power transistor is near the coil

[alex7542]

Hey nistech im not sure exactly were the eccs is. and the power transistor is the black box screwed onto the coil braket? and i was thinking could it be the ecu thats bad.

[NISTECH]

it could be but I wouldnt jump to that conclusion yet. If you have a DVOM with 10 meg ohms impeadance you should check to see if the wire from the distributor that signals the computer to fire the coil is pulsing. if the computer is recieving the signal and the coil does infact have power you need to see if the computer is signaling the power transistor to fire the coil. where did you get the wiring diag for the ignition system?

[alex7542]

I got the wireing from mitchell on demand.and i have a dvom and we tested the wires goign to the coil for voltage and they do have power. but then i tested the wires going to the power transistor which is 4 wires i belive its on the back of the coil. it did not have power. no wires had power. and then i tested the distributor wires and same thing no power.

[NISTECH]

damn if I woould only learn to read back posts I would of known that...doh!!! on your diag trace the power to the dist to the supply source fuse or relay. if you have power there you need to follow the wire along its path to determine where it drops the power.

[alex7542]

the power that i saw on the diag is on the eccs relay. thats y i was asking. because the others one black and white goes to the afm. then the other two go to pins on the ecu

[alex7542]

Hey Nistech.I did a diognastics on the ecu today and got code number 55 whcih is nothing on the computer. no malfunction recorded i believe.I was thinking maybe its the power transistor that went bad for some reason. but im not sure if the power transistor went bad does this cause the distributor wires to go out.

also another thing i forgot to mention whcih i figure out yesturday was that my timing is set at 0 degress tdc. i had put the crank on the red mark which is tdc and then put the distributor on number one. BUt the car seemed to run fine and rev out wit no problem wit it was first running.thanksAlex

[NISTECH]

TDC is fine it will still run and have spark. I really need to look at your diagram for your power to your dist. before I can give you any more definite answers. I have a disc with all 240 service manuals on it I havent loaded it up yet to my other comp I will soon and I'll look up your car and see if I can provide you with an avenue to go.

[alex7542]

Ok nistech thanks. But with tdc will the car run right or very sluggish?and i have a feeling it could be the power transistor but not sure. today im going to see if theres current running threw the wires connected to the power transistor.

[alex7542]

Hey nistech.When you have a chance. can you tell me how much the power transistor cost. Because i checked the wires in that go connected to it and they have power. but then i checked the power transistor for resistance and i got no results. so i belive the transistor is bad. now i dont know why it would have gone bad but can you tell me how much it cost.thanks
