Well, if you have no spark I think you've narrowed it down considerably. It ain't gonna start without a spark. The alarm going off may have something to do with it, I think that also kills the ignition. You need a working code reader now, it sounds like it's not something simple and easy to diagnose, like a fuel pump problem. -Paul |

I just used the code reader a month ago and it worked fine, that how I replaced the EG sensor. I hooked a fuel pressure gauge, but that doesn't register (fuel did come out of the valve). Does the engine need to be running? ..45 round thru the block :-) Jim |

What would cause the reader to not work, no fuel pressure, and no spark??? The link indicator on the reader comes on , but nothing else. Jim |

I went back out and it had cycled thru and came back 111-system pass. Additionally, the fuel pressure gauge had a reading of 38PSI. Guess that leaves just the spark issue! Jim |

Are you sure? This is EECIV, not OBDII. Doubt if those can self-diagnose

Now it gets really bizarre. When I finally got the reader to cycle thru the test I heard the fuel pump run and then the fuel pressure gauge shot up to 40psi then dropped to 37/38psi and the pressure held. Then I was able to start the engine. I then shut the engine and disconnected the fuel pressure gauge. I tried to start the engine again with no luck. I reconnected the code reader and ran it thru the test cycle, at least until I heard the fuel pump run. Then the engine started. What the #$%& would cause the fuel pump run when the code reader is connected, but not when I turn the ignition on. By the way, I still had no spark, therefore I must not have had it set up correctly and spark all along...I guess. Any Thoughts? Thanks Jim |

This is a gross failure, not something like one cylinder miss firing. But I'm too lazy to look it up, and if anyone knows for sure I'll defer to their greater knowledge. -Paul |

So if the computer is sensing a code that tells it to cut off the spark or fuel, that is a possible explanation. But this is getting beyond troubleshooting by text messages. -Paul |
