98 Chevy Vortec 5.7 NO SPARK

I have a spark problem, I have replaces cap, rotor,plugs, wires, coil, coil pickup, ignition Mod, crank sensor, and still have no spark at the coil. Is it true that if the fuel pump does not have 50 -60 pounds of pressure that it would tell the computer to not spark? Any help would be appreciated. Thanks

I would make sure you have voltage to the coil. Could be a fuse or relay problem. Is the check engine light on when you turn the key on ?

That is indeed odd. I would suspect problems with the hi tension cables if this was not part of the ones you changed since the flow of current ends at the distributor. Check also other cables such as the ground. It is puzzling that all plugs would not have any spark. I would also recommend a scanner used to check for error codes given out by the car's ECU.

454 engine will not start . Replaced cap rotor plugs and plug wires . Also replaced pickup coil and had coil , ignition mod checked out


CHECK THE IGNITION FUSE OR IGNITION MODULE FUSE AND CHECK ECM FUSE ALSO. TELL ME ARE YOU GETTING FUEL.YOU DID NOT MENTION YEAR AND MODEL.BECAUSE CRANKSHAFT SENSOR WILL CAUSE NO SPARK ALSO.

Car cranks but wont start


ENGINE CRANKS BUT WILL NOT START
When the engine cranks normally but won't start, you need to check ignition, fuel and"http://www.aa1car.com/library/compression.htm". Ignition is easy enough to check with a spark tester or by positioning a plug wire near a good ground. No spark? The most likely causes would be a failed ignition module, distributor pickup or "http://www.aa1car.com/library/crank_sensors.htm".
A tool such as an Ignition System Simulator can speed the diagnosis by quickly telling you if the ignition module and coil are capable of producing a spark with a simulated timing input signal. If the simulated signal generates a spark, the problem is a bad distributor pickup or crankshaft position sensor. No spark would point to a bad module or coil. Measuring ignition coil primary and secondary resistance can rule out that component as the culprit.
Module problems as well as pickup problems are often caused by loose, broken or corroded wiring terminals and connectors. Older HEI ignition modules are notorious for this. If you are working on a distributorless ignition system with a Hall effect crankshaft position sensor, check the sensor's reference voltage (VRef) and ground. The sensor must have 5 volts or it will remain permanently off and not generate a crank signal (which should set a fault code). Measure VRef between the sensor power supply wire and ground (use the engine block for a ground, not the sensor ground circuit wire). Don't see 5 volts? Then check the sensor wiring harness for loose or corroded connectors. A poor ground connection will have the same effect on the sensor operation as a bad VRef supply. Measure the voltage drop between the sensor ground wire and the engine block. More than a 0.1 voltage drop indicates a bad ground connection. Check the sensor mounting and wiring harness.
If a Hall effect crank sensor has power and ground, the next thing to check would be its output. With nothing in the sensor window, the sensor should be "on" and read 5 volts (VRef). Measure the sensor D.C. output voltage between the sensor signal output wire and ground (use the engine block again, not the ground wire). When the engine is cranked, the sensor output should drop to zero every time the shutter blade, notch, magnetic button or gear tooth passes through the sensor. No change in voltage would indicate a bad sensor that needs to be replaced.
If the primary side of the ignition system seems to be producing a trigger signal for the coil but the voltage is not reaching the plugs, a visual inspection of the coil tower, distributor cap, rotor and plug wires should be made to identify any defects that might be preventing the spark from reaching its intended destination.----
thanks for using fixya,please do rate the solution positively.

The crank angle sensor maybe bad. It sends a signal to the computer so the spark plugs fire up.

No fire or spark


Souds like ignition module has failed. Check for 12 volts to mod and replace mod if voltage is good.
