  • bmark341 Jan 12, 2009

    had the ignition module tested at two different part stores....tested ok....the coils tested slightly below specs

  • bmark341 Jan 13, 2009

    they tested it till it was pretty hot...a good ten cycles on the machine....is it possible the crank sensor could be the problem

    When the car is really cold it is very hard to get it into first gear. After a few minutes of running it is OK again

After it dies, try starting it by holding the pedal to the floor then turning the ignition. If that works, it means it is actually flooding the engine and choking it out with too much fuel. The one thing you said that jumps out at me is the temp sensor you changed. Which one did you change. Most people think their is only one. If you changed the one on the front right of the engine right next to the coolant outlet hose than you changed the wrong one. This one has 4 wires, and that goes to the actual temp gauge, which effects nothing but the guage in the dash. The one you want is by the thermostat housing and has only 2 wires. It is about half the diameter of the guage one.

I'm not an expert, but maybe a can of Sea Foam fuel system cleaner with the recomended amount of fuel in the tank; and pour half of another can in with the oil; and lightly dip up and down the end of the vaccum line from the vaccum booster until the rest of the half can of Sea Foam is siphened up while the engine is running might help. You want to be sure and lightly and slowly dip the vacuum line up and down in the Sea Foam so that you don't get too much Sea Foam in the way of the cylinders in the engine going up and down: ( That could cause damage. ) Then shut the motor off and w
ait a few hours so that the Sea Foam can do it's work. Then try starting and running it to see if it helped any. Sometimes an old car needs the vaccum line thing done two or three times. ( I've found Wal-Mart has the best price on Sea Foam. ) Good Luck Hopefully.

Sounds like the air bypass valve may be stuck ,try pulling off a small vaccum line. the valve is used instead of a choke plate. when engine is cold it bleeds air around the throttle plate raising the idle.

    try changing the module (the thing that the coils are mounted to). i thought you had trouble when cold thats why i said airbypass.

  • darin brown Jan 13, 2009

    a module could test good at parts store but they commonly fail when they heat up. so by the time you pull it out and bring to store it has cooled down.

It won't crank up and it sat up 2 years


No gas, plugged fuel filter? Turn on the key but don't crank engine, listen with door open towards gas tank. You should hear a click and a slight motor pump noise for a couple seconds. If not then your sending unit failed.

1989 Bronco fullsize has sat for the past 6 years and wont start, will turn over, has new gas with fuel stabilizer, still no firing. Replacing spark plugs and the fuel pump are the next two steps. ...


Assuming she ran good before she sat, replacing the plugs, cap and rotor isn't a bad idea.Step 1: Make sure you have good spark. No need to worry about timing right now. Step 2: If you have spark, then we have to see if its getting gas. There are two fuel pumps on this Bronco. One in tank and one on the frame rail. Can you hear either one running? The in tank one should come on for a few minutes and shut off. The front one is harder to hear.If you hear it, borrow or rent a FUEL PRESSURE GAUGE and check your fuel pressure. There is a fitting similar to a tire valve on fuel rail. Pressure should remain constant.If either pump fails you will not get adequate fuel flow. The front pump is easy to get to for trouble-shooting. Don't buy anything unless your sure you will need it. Hope this helps.

Check the fuel for a presence of water. I'm sure there was a recall notice on the gasket on top of the fuel tank where the sending unit mounts. My YJ sat for a year and had water in the tank from this leaking. Drain and drop the tank, replace the gasket, and reinstall.

I have a 88 Fiero GT V6 that has sat for over a year without starting. I put in 5 gallons of gas, and used starting fluid. Starts, but only keeps running while fuel is poured into intake. I suspect water...


1) Running fuel pump to remove water from tank will likely not empty it all, but it might help. Will still be some liquid in bottom of tank.

2) More than likely, the gas has gummed up and is no good, While your draining of the tank will help, may still need to change the fuel filter and clean the injectors. The ability to keep engine running while pouring into the intake is a good sign, but mayfind that more parts need to be cleaned and replaced prior to solving the problem.

Hard starting. cranks several times before starting. runs fine.


Sounds like low fuel pressure or a stopped up fuel filter. If the vehical has two tanks does it act the same on both tanks? there are fuel pumps in both tanks and one one on the frame. if the one on the frame is slow or not working the tank pumps can still run the car sometimes but it has troble getting started

TRUCK DIES AND WONT START FOR A FEW MINUTES, SOMETIME IT WONT START BACK UP FOR A FEW MINUTES


The next time this happens and the vehicle won't start back up, turn you ignition switch off and when you turn it back on have someone listen near the fuel tank for the fuel pump to make a humming noise. Your problem may be a bad fuel pump or a bad electrical conection to the pump.
