Question about 1984 Jeep CJ7

1 Answer

I replaced the coil with a new one with still the same results. It was driving fine then acted like it was flooding and blowing up out of the carb. I stuck a screw driver in the carb thinking that the choke was sticking and still it wouldnt fire. I got to looking and measured my volts at the coil and had 7 volts. So I took the wire off and it read 12 Volts. Naturally I thought it was shorted but when I put the new one on I got the same results. I have 12 Volts coming to the coil and it is a new coil. What kindof volts should I read with the wires hocked up to the coil 12 right? How many ohms should I read across the coil? Somebody please help me fix this thing!!!

    I measured my volts with both wires on the coil and the red wire coming in read about 7.8 volts. I took the wire off and the wire read 12 volts so I put a new one on and got the same result. I thinking maybe it has something to do with the timing and not the coil. What do you think?

    Well when I roll the motor over it acts like its going to start and does with me holding the key over and pumping the gas but as soon as I let off it quits and steam shuts out of the carb like its flooded or something. The reason I was looking at the coil was thinking it wasnt firing, but I took a plug wire off and held it close to the block and it sparked a little bit. At this point I have no clue what to check or do next. Can you help me?

    I have fuel and spark but it still wont start why?

  • alwilliamson Oct 01, 2009

    if you have fuel and spark then why are you fooling with the coil, sure don't understand the resoning here, check and see if the valve timing is correct, u may have munched a timning chain, also make sure the distributor rotor is not burned through, it can spark fine fine with no load from the cylinder, buy short through the rotor when hooked up to tjhe plug, t takes allot more voltage to fire a plug in the pressurized eviorment of the working cylinder.

    do u have spark?

    timing has nothing to do with this, please explain your thoughts on why it would..

    u should nothave 12 volts to the coil, about 8.

Put it at TDC on #1 and look at where the rotor is pointing. Think timing chain

2004 ford taurus dohc doesnt want to idle when cold and when warm at stop signs after driving for awhile it acts up like its flooding out. it will idle warm


Sounds like an O2 sensor, however you might try cleaning the MAF sensor in the air intake hose with carb cleaner (blow it out after spraying it and put it back in). MAF sensors are expensive and you can clean them with spray cleaner or starting fluid and usually not have to buy one. O2 sensors are cheaper and won't cleanup using this procedure.

My 1999 Cherokee Limited, 4.0 liter automatic stumbles and/or hesitates at tip in after you first start it when warm. It acts like an engine with a carb that has a bad or improperly adjusted accelerator...


Could you explain this a little better , hesitates at tip in after you first start it when warm > hesitates at tip in ???? plus after first you first start it when warm . What's warm ? the engine ? The temperature out side ? Or after you had it running an shut it off an restart the vehicle ? The engine temp. is warm , hot etc.... cooling fans working , vapor lock ?

Starting problems


since the computer is only supposed to send fuel and spark signals in reaction to input info, unless a wire in the harness is either grounding or crossing into an output wire, i'd think it's safe to assume the computer is doing that internally. Another reason is that if it were a wiring problem, pretty likely it would not run well after you did get it started.
The only thing I'd do aside from replacing the computer is to unplug all the sensors one by one while it is acting up, to get an idea about wether the errant signal is coming from a sensor or internally.
Likely you can get another computer from a scrapyard.for lots less than a new one. Since this is a "guess" repair, you may want to try that.

What is causing my 1986 jeep grand wagoneer engine to stall while driving? I cannot restart it but there is power. It will turn over but not start and there is gas in it. The jeep just went "poof" and died...


ok, its and old jeep, cranks but will not start.

carb fueled right? crank it wide open throttle to clean the flood
and block open the choke, if CARB has auto choke, if manual choke make sure its open. (push in knob... called choke)
fuses first. test them.
first check for spark in all cylinders.
if you have spark on all , then its flooded.
if no spark on one try a new spark plug and wire.
if all spark is dead , do the tuneup. now. all spark parts.
if spark is dead, check it at the coil, ? good there? or not.
that is a start.
if the carb is bad, we cant cover rebuilding it here.

stalls while driving has over 50 causes.
but bad spark or flooding tops list. (assumes engine is ok)

You are on the right path. You gave away the answer when you said you can dry the plugs and then it will start and run for a few seconds before flooding out again.

To solve the problem (there seem to be two of them) do the following:

You need to stop fuel from entering the engine, either disconnect the fuel line from the tank to the fuel pump or route the output from the fuel pump to a gas can or back to the tank, just don't let it get to the carb.

Pull the coil wire, pull the plugs and spin the motor over so it can get dried out.
Pulling the coil wire should help reduce the risk of the fuel being blown from the cylinders from somehow getting ignited. BE CAREFULL!!!

Now dry the plugs and put them back in, plug in the coil wire and fire it up. Based on what you have said it sounds like it will probably start up (if only for a second or three). Now pour two or three teaspoons of gasoline into the carb and start it again.

If it starts and then dies that is a good thing. Do the two or three teaspoons and start it two or three times. This will heat up the compression chambers a little and help to dry them out a little better.

Now, at this point it runs fine (well as fine a 2 or 3 teaspoons will run it) as long as it has fuel, air and spark.

Hook up the fuel line again and start it up. One of two things will take place.

1. All is well! Great, it was just REALLY flooded.

2. It runs for about 10 seconds before becoming flooded again.... ****, it sounds like your "new" carb is flooding the engine. Find out how!

Good luck. I have used this "fix" a few times over the years. Normally the engine is REALLY, REALLY, REALLY flooded. Usually because the original problem happened on a hot summer day and the float stuck when the engine was shut off. The heat of the engine boiled the gasoline which in turn flooded the engine. The float stayed stuck when they came back to start it and TA DA.

Several times a little tap on the side of the carb "cured" the problem and a fuel additive was used to clean up the sticky float issue.

In one instance the 4 banger was so flooded we had to snake a hose into the cylinders and **** the fuel out. We must have sucked a quart of fuel out of that little '80 Mustang. We still ended up draining the oil (it smelled like it was full of fuel too) and we spun it over until it quit spraying gasoline all over. Man was that a mess!!!

Intermitent stalling and hard starting when cold


sounds like it could be a vacuum leak--check all of the small vacuum hoses around the carb....

The truck won't start, Fuel pump is a year old, just changed out heat sensor, just changed spark plugs- truck will start when chemical is sprayed into carb looking thing. Also will start when truck is...


Check that the Idle air controller is not faulty, disconnect it and start the truck again, if the truck starts (running poorly) then replace the IAC.
