if you have replaced cap and rotor plus coil and it seemed to fire up then i would take the next step. For sure put your new plugs and wires on then make sure you have replaced your air filter, and change out your fuel filter, fire up the vehicle if it doesn't start I would suggest changing the fuel pump. If it starts up make sure you put in some BK fuel injector cleaner in your fuel it might be you have dirty injectors. If all fails then get back with me and we will look else where. Good luck hope this info helps you out
First you must determine if the fuel is stopping or the spark is stopping..If the fuel is stopping this could be a computer problem.. If the spark is stopping then it could be the IGN Module in the distributer. or any nomber of sensors. Squirt a little fuel directly into the Throttle body on the intake manifold.. If the truck runs longer its probably loss of fuel.. Do this several times to make sure, be careful and only use a small amounty of fuel.. you do not want a fire.. RE: Spark: Take a plug wire and an old plug..put the wire on the plug.. hold the plug against a good ground .. have someone crank the engine .. does the plug stop firing? The engine dies.. and will not restart for a minuet or so.. during this "no start" time do the plug test. If the plug will not fire during this time take the module out and take it to Orillys Auto parts.. They can test it.. really expensive part. Don't replace until you know it is BAD..
3 things keep a motor from starting.1. NO SPARK, 2. NO FUEL,. 3 ENGINE DAMAGE. I SUSPECT IT IS THE IGN MODULE WHICH IS INSIDE THE DISTRIBUTER. cHECK TO SEE IF IT HAS SPARK.. iF IT DOES THE IGN MODULE IS NOT THE PROBLEM. iF IT DOES HAVE SPARK CHECK TO SEE IF IT IS PUMPING FUEL.. DO THIS BY SQUIRTING A LITTLE FUEL INTO THE INTAKE MANIFOLD THROUGH THE INTAKE AIR HOSE RIGHT BEFORE IT CONNECTS WITH THE INTAKE MANIFOLD. .. iF THE MOTOR FIRES AND TRYS TO RUN YOU KNOW FUEL IS THE PROBLEM. IN WHICH CASE IT COULD BE A CLOGGED FUEL FILTER OR A INOPERTIVE FUEL PUMP. iF IT HAS FUEL AND SPARK LOOK FOR A BROKEN OR STRIPPED CAM TIMING BELT. NOT TURNING THE CAM OR CAMS.
next time it dies, cranks and wont start, do this if you have someone else with you. carry a spare spark plug, then when the problem arises pull off a plug wire put the spare plug into it and ground the end somewhere in the engine bay, then have someone bump the key and watch to see if the plug has a spark or not, that will at least tell you what problem to go searching for. if it had air, it still does when it dies so it will either be spark or fuel related. just because the pump runs, doesnt mean the ecu is telling the injectors to fire, so still could be a fuel issue. is the check engine light on?
check for spark. use an inductive timing light on a plug wire while your trying to start the car and see if you have spark. if you do the next place to check is the fuel system. it it getting to the cylinders. just because the fuel pump works doesnt mean it is pumping fuel to the motor esp if fuel injected which requires a pretty high pressure of fuel delivery compared to mechanical fuel pumps. get back with me after you have checked these two items if it still wont fire or run. good luck. remember dont open up the fuel system and have any exposed fuel while trying to start the motor. very high risk of fire or explosion with this combination.
assuming the starter is good and the engine turn over fine but will not fire or run. when the car die, check why is it so hard to start. check if you getting sparks and fuel, no sparks check coil and wires,and if both are good than the cam sensor is bad, no fuel, check the fuel pump, pump good check the crank sensor.
I would have a close look at the fuel pump.These are one of the weaker links in the vehicle.Key On -Engine off will run this intank electric pump for 3 seconds.This gives you an opportunity to listen for the pump and how it sounds overall(in a quiet place ,like a closed garage)...Sometimes a failing pump sounds a bit squeelish and loud,somewhat labored.A good working ,fresh pump sounds very smooth and quiet.Fuel pressure diagnostics might be in order as these pumps seem to work about like they sound....good luck
Rule 1 ....WD40 is non-flammable. It used to be an effective starter spray for diesels. Unfortunately it now contains a fire retardant to prevent accidents....so the rev you were looking for wont arrive.
It does work well with easy-start/ether though.
I suspect you found a vacuum leak and sucked WD40 into the intake....If u think u did you'll need to clean your plugs.
A strobe lamp to check the spark would be a good idea. Also if a lil squirt (VERY LITTLE) of easy start doesnt produce at least a backfire, your spark is out.
