Well Dave you just can't replace parts an hope you fix it ! There are test that need to be done to find out what system is malfunctioning ! If no spark , the ignition system is at fault ! An that could be any one of a number of things , ignition control module , engine computer ,crankshaft position sensor. If the fuel system is at fault is there battery voltage getting to the fuel pump through the relay , is the PCM turning on the relay ? The relay is most often a four pin relay an where it plugs into the fuse / relay box you can test for power an ground an control of the circuit ! Another possibility would be the anti-theft system not letting it start, any light like SECURITY lit on the dash ? Rather then just replacing parts Dave in a random fashion ,you need to find out what is missing fuel , spark an is the engine in good mechanical condition an no SECURITY light ! good luck Dave !

You spent more on parts then it would have cost to take to a repair shop !

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.

1995 chevy full size van, cranks wont start Replaced fuel pump, rotor, dist. started once but now why does it crank but won't start?


It could be a bad fuel pump relay. Or the relay is not getting the proper signal from the pcm to turn on. If a new relay doesn't fix, have the relay's circuit checked.

Replaced bad fuel pump, installed new relay and fuel filter, engine turns over but is not firing on..... positive the fuel pump is pumping gas and checked to see if gas was going thru fuel filter. Tried...


Hi, Ok you have confirmed that it's not a fuel problem. You need to check for spark. Pull the coil wire off of the coil(secondary lead-looks like a spark plug wire) Have some one crank it over and listen for a popping sound. IF yes, spark is at the coil, that means all ignition sensors are working. Next check for spark at ends of wires after cap. IF no replace cap and rotor. IF yes remove a couple spark plugs and check for fouling(wet, fuel etc...) IF yes replace or clean plugs and retest for starting. IF no spark is present at coil you need to scan computer and watch for rpm signal. IF no rpm signal, replace crankshaft sensor with OEM delco part. BIGGEST problem with these engines is Cap and Rotor burn out.

I have a 1999 dodge durango,i replaced new spark plugs and new wires but the car won't start?


Do you have crank no start? (see entire write up)
b)No crank no start?, ( battery, battery cables, neutral safety switch ignition switch,,starter relay)
c)No dash lights, no crank? (battery, battery cables, ignition switch)
If you have symptom A then the affected items are , ignition switch, battery, battery cables, starter, starter relay ,coil, coil pack, ignition module ,Distributor cap ,rotor, (if applicable) spark plugs and wires.
The best thing to do is to first make sure your timing belt didn't break. As long as the engine cranks you can do this. Give the battery a 3 min charge . Then have a helper crank the vehicle while you observe the rotation of all the pulley's and belts. They must rotate together. If the vehicle has a distributor remove the cap ground the coil wire and watch the rotor as the engine is cranked. it should spin. If this is a-ok your worse nightmare is over.
Now we have eliminated the timing belt as being a cause. We now have to charge the battery again for three min and load test it( this is best done by a repair shop a load tester is expensive .If the battery is more than 5yrs old you may want to replace it.
If battery does not pass load test replace it.
Whatever you decide the rest of the items can NOT be checked out without a fully charged battery.
Check ignition switch and starter relay for B+ going to them and leaving them. Check starter circuit.Do not forget neutral safety switch its on your brake pedal and once depressed it closes the circuit to the relay so B+ can travel to it . Make sure B+ is making it to starter ( use a digital voltmeter). If B+ (12 volts) is making it to the starter and it doesn't crank then the starter is defective. Do a starter current draw test to verify this or remove the starter and have it bench tested.
If starter cranks now your into coil testing .
Pull a spark plug hook it up to a spark tester and ground it, now crank the engine if you get spark coil is ok and in all likelihood so is module.
If you don't get spark test for spark at the coil wire.
If you get spark here and don't get it at the spark plug wire problem is at distributor cap , rotor or spark plug wire. IN YOUR CASE YOU HAVE NEW PLUGS AND WIRES SO IT WILL BE EASIER TO CHECK FOR SPARK.If all of the above are a-ok.
Next is fuel checks.
Easiest fuel check is to put key into ignition cylinder and turn to on position. Lister for pump to buzz or hum. if it doesn't then check fuel pump relay for B+ going to it and leaving it and going to the pump. If B+ making it to pump and it doesn't turn on the pump is your problem. If B+ not making it to pump either the relay or the ignition switch is defective.
Naturally if the pump is defective have a repair shop do the repair .THERE ARE FUEL PRESSURE AND VOLUME TESTS DONE TO VERIFY IF PUMP IS DEFECTIVE OR NOT. IF WITH THE TESTING PROCEDURES I'VE GIVEN YOUYOU CAN NOT DETERMINE WHETHER THE PUMP IS DEFECTIVE HAVE A REPAIR SHOP DO FURTHER TESTING ON THE PUMP. THESE TESTS ARE A LITTLE DANGEROUS and a real pain.
Good Luck

Engine not getting fuel


might look at the spark plug wires and plugs make sure none of the wires are burned or cracked destributer cap could also be a culprit or the rotor or the coil .
