SOURCE: 454 on chevy won't idle

Did you check your timing? You may have the timing to advanced to compensate for the clogged filter, change your timing and then see if it will idle.

SOURCE: chevy 350 no spark

Check the distributor module (ICM), it may have gone bad and needs to be replaced. It's around $40.00 and it's under the rotor in the distributor assembly. Check the red lead wire to the HEI for voltage, there should be 12 volts. It common for the ICM to fail on the HEI system and if you go to Auto Zone, they can give you the step by step instructions to replace the ICM. Good luck and keep me posted, be glad to help.

before you drop tank again, check fuses & relay.then disconnect fuel line @ filter turn key to on position should hear fuel pump run and get gas stream out of line. if no flow from line new pump faulty be sure & remove negative battery cable first good luck.

SOURCE: 87 chevy 350 fuel injected pickup wont run smoothly

sounds like your egr valve is gummed up or bad. this is located behind the throttle body and has a single vaccum tube connected to it. if the diafram is still good you can remove it and clean it with WD 40 until the plunger works smooth

secondary are between 900 ohms to 12,000 ohms

2000 mazda protege 1.6L my spark plugs are getting soaked with gas


bad fuel injectors. bad spark plugs - inspect and or replace -- bad spark plug wires - test ohms resistance of the spark plug wires with a multi meter (5 bucks at harbor freight) -- or simply replace the spark plug wires.
How was it you tested the coil and spark at the plugs?

p0300 is a multible/random misfire, did you change the plug wires also !
  • Faulty spark plugs or wires
  • Faulty coil (pack)
  • Faulty oxygen sensor(s)
  • Faulty fuel injector(s)
  • Burned exhaust valve
  • Faulty catalytic converter(s)
  • Stuck/blocked EGR valve / passages
  • Faulty camshaft position sensor
  • Defective computer

    If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.

first, check all the fuses
did you check to see if there's spark at spark plugs?
did you check the fuel pressure? you need to do that to isolate fuel and ignition system.
if there is no fuel then check for fuel pump operation
if there is no spark then check the ignition system (coil, module and wirings)
if you don't have either one then the problem is in the computer system such as crank sensor, and computer itself

Change the distrubutor cap, rotor, and spark plug wires with spark plug if you haven't already. If this problem still exists check the fuel pressure at the fuel rail schrader access valve it is a spot on the fuel rail with a cap that must be unscrewed

Check the resistance of the pick-up coil in the distributor. Reading should be between 800 to 1200 ohms. Disconnect the two wire connection at the distributor control module to measure the resistance.
Let me know.

95 Chevy Silverado.


To bypass the other switches, run a wire from the battery to the starter bendix and if it cranks then the problem is in the wiring or the switches you mention.
