Check to see if you have power to the distributor,you should have at least 12 volts on the black/white wire.
don, just checked I have a black / tan wire. The test light shows power but the multimeter reads 11.9 volts. The wire i tested if plugged into the ditributor would be the closest wire to the firewall. this car has had a oil leak and really haard to tell color of wire.
If you have an ohm meter check the #1 & #2 terminals at the coil they should ohm at .56-.68.If that is good check from the #1 terminal to the out put terminal on the coil it should read 9.4-12.8.If those readings are not correct replace the coil.
are the the terminals marked on the coil 1 an2? Also where is the output terminal on the coil? Now when i mentioned that i replaced the distributor,i meant the whole thing. The parts store said it included the coil. The repair manual said that the coil wasnt servicable to replace the distrbutor.Is this true? local cost was 300. this did not help. still no spark. i will check with ohm meter this evening if you will clarify the correct terminals. I checked terminals before but may have had wrong ones. let me know what color the wires are on the plug then i can check that terminal on the coil/distributor. I was able to return the distributor for a refund. old/ original distributor is back on car. no spark on any clyinder at distributor cap. Thanks
Don, ok here we go. first if it matters. My plug for the distributor has 7 wires. Next what you call black/ white mine is black/tan. your white wire corressponds to a tan wire on my plug if this matters. My test results are as follows
Plug on car
black/white 11.9volts, white wire no volts with key on! ground wire tested good. The ECM ground tested good. Now on to the distributor terminals. #1 and #2 tested 0.9 ohms. #1 to the output had no reading. Do I change the distrbutor. The white wire not having voltage throws everything off for me. What do I do next? What feeds voltage to the white wire?
Forgot, I had no codes stored. When this first happened it thru the multiple cylinder misfire code. I have erased it since. I have an actron code reader. generic but works.I did cycle the key three times to check and had no flashing check engine light, and nothing on the odometer. Thanks again for yur help!!!
Don, I have no pulse. However i am trying to check it by myself. Kind of hard to crank the car and hold the test light. Where is the ecm on this car? I am going to check #3 wire on plug again later when i get help.
Don i put cap and rotor back on. I took out spark plug out and put it in plug boot held on ground then put black/blue #3 wire to ground and spark plug did not fire. I am going to see if i can find a noid lite and see if I have a pulse on #1and #3 wires while cranking.
Don used noid lite across #1 and #3. I turned key on and lite come on and pulsed while cranking. So that means coil is bad. correct?
Don, rotor does turn and no voltage at pole according to the test light
I am going to try to get one mon. or tues. Thanks
Battery voltage drop to 10.9 at battery while cranking. Still 10.2 at terminal
I know we will. My wife just bought this. She has just started a new job and has only driven it to her first interview, Back to the car. Don, you mention the ground. the coating has come off the ground where it is fastened to the inner fender well. I will go ahead and check and possibly replace. I will keep you posted. Thanks Rich
Don, compression check is completed. #2 has130 lbs. #4 has135lbs. #6 has 130lbs. I noticed some thing this evening ,while working on the car. what is supposed to be under the passenger seat on this car? Looks as if there was some kind of module there. I found two terminals under there and some of the wires were spliced together. Looks like to different terminals. ( wont plug together) all connections are good. Any idea what has been by-passed???? Perhaps my whole problem.... Thanks Rich
Really starting to think we should have passed on purchasing this car....
I understand about the phone, just easier to talk sometimes. You mean the mass air flow sensor I assume. It just revs up slow Don. It will idle after you keep it running a few minutes. When u snap the throttle it doesnt seem to be very responsive. It will idle down and die at times after it has run for awhile or you try to take off in it. The timing marks are correct. I have no codes as far as the ecm recognizing any sensor malfunctions, other than the o2 sensor yesterday. I put the Snap on mt 2500 on the car and it showed the ignition advance from 15 degress to 29 degrees. however i am not sure I trust my knowledge on this tester. that is why I asked about the phone call. I will get with the person that i borrow it from. I think it heats up to fast as far as seeing heat waves coming from the engine. The engine is normal operating temp per gauge and scan tool. coincide..
It's backfiring every now and then also. I unplugged the mass airflow sensor and it made it worse. I'll check the fuel pressure latter. Planning to get an infrared heat gun to check the exhaust to see where it is the hottest.
Don I agree with you about distributor.I know it will run with the junkyard distributor in it. It does however still run badly. Sluggish, not very responsive.... Do you have any idea where to start on checking the wiring?
Don, they couldnt reference that oem number in the above message. They called dodge and was advised to check the engine vaccuum, spark plugs, and to remove the O2 sensors to see if that helped, which they had done the the o2 sensors already... wait and see what tomorrow brings.
I was going thru some of the paper work we have accummalated on this project. I have found a printout where we had stopped at a autozone because the checkengine light come on. The code was PO442. I am sure you know this butI will go on. causes are as follows. evap system small leak no flow, evap system is monitored for its ability to hold vacuum.symptoms gas cap,evap canisteror hose cracked,purge or vent solenoid defective,and last vacuum leak at engine... could this be it. no code like this since.
Don, The roll pins on the sensor plate i took off were also loose where they attach to the plate. They had alot of play. I will be in touch next week. Thanks for hanging in there thru all this. Wow, what a mess. Heading out in a few to Dodge to ordser parts. You have a great weekend!! Thanks!!!!
Don, Hope that we can keep in touch. You have been a tremendous help with this car. I hope to hear from you time to time. My e-mail is [email protected] I will keep this account open until it renews then will probably close it. If i dont hear from you have a great rest of the year. Thanks a million. Rich and XXXXX XXXXX.
