Truck stop while driving on hwy. replaced fuel pump, fuel filter, wires plugs cap rotor but still no start


Have your ignition module checked, my car would start and drive and would go dead after a few miles and would not start until it cooled down, turned out to be the ignition module that eventually went bad and would not start at all.

Have replaced the starter solenoid, spark plugs, plug wires, fuel filter, air filter, water pump and battery all within the last two months. When the truck gets hot it will not crank. Has electrical power,...


If you haven't already done so, replace the distributor cap and rotor. There is most likely corrosion inside the cap that is causing a crossfire condition.

This is a common problem on that engine.

Don't know why being hot would aggravate it, but start with the cap.

Galant Special Edition 1994 Motor does not start


this maybe caused by no fuel or faulty fuel pump, ignition coil, wire and plug crank position sensor. first check for spark by removing on spark plug wire and put a spark plug in the spark plug wire boot, donot touch the plug only the boot have someone crank the car over. if you see spark, that part of the ignition is good. if not, check the coil resistance if should 40 to 80 ohm with a volt meter pf not replace. if ok, but no spark check the igniton control madule make sure the coil and module are receiving current. if not check the fuse that feels them. if it is ok, check distributor cap and rotor. if rotor and cap are fine, check for fuel at either the fuel filter, the fuel return line or removing some spark plug and see if they are wet. if there is no fuel check the fuel pump and the fuse and relay that control the pump. if there is fuel with high pressure but there is no spark, check the crank sensor for signal with a volt meter while cranking the vehicle
