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

Hello! Here is a beastly repair that has got me overdone. 2000 S10 pickup 4.3 Vortec stalled out then wouldn’t crank or start. Replaced the starter, battery & alternator which produced a crank no start...

You'll need to verify spark at the ignition coil secondary (coil wire that goes to the ditributor). If you dont have a spark tester, remove plug from cylinder 1, disconnect coil wire from distributor and connect to the plug you removed and ground plug to engine steel, have someone crank engine and observe spark.

Before you remove spark plug, crank engine for a few seconds, then promptly remove plug. If its wet with fuel then at least you know injectors are working. If dry, then likely injectors are not activated by ECM. Go ahead and confirm spark and then figure out why no fuel from injectors.

1989 f-250 5.0 engine cranks but won't start

  1. The ignition system on your 5.0L uses a distributor type system and will include the following components:
    1. Ignition control module (ICM). Depending on the year of your specific Ford, it'll have a inner-fender mounted ignition control module or a distributor mounted ignition control module. hot sure which you have.
    2. Ignition coil. you replaced it.
    3. PIP (Profile Ignition Pickup) sensor. This is Ford's name for the crank sensor and is mounted inside the distributor. The most common name for this component is the pick up coil.
    4. Distributor cap and rotor. you replaced
    5. Spark plug wires. you replaced.
  2. The thing to keep in mind about the ignition system is that all engine cylinders must get spark and the one thing that will stop the ignition system from creating spark on a wholesale scale is a BAD crank sensor.Have you pulled a plug then using some insulated pliers grounded it to the vehicle and turned it over to see if you have spark, that'll tell you alot.takes two people of course.Best of luck and hope this helps.
