Ok i'm going to cut to the chase here. I put new plugs in, changed my CAI to the stock setup. It ran beautiful down the road (about 1/2 mi), stumbled, and wouldn't restart.

Problem: The car cranks and cranks but just won't start or run.

1. All gauges work, interior lights, battery has good charge and is not a charging issue.

2. Code reader won't work for the Key On Engine Off test. I changed the batteries in it, retried about 30 times. And it just sits there and won't do anything. ECM relay maybee?

3. Spark: Nothing anywhere, swapped coil and nothing, rechecked plugs are brand new.

4. TFI module: Does not get voltage to the harness, backprobbed the 1st terminal (dark green wire) for the stator connection and it does not flash while trying to crank. I removed it and autozone tested it and said it is fine.

5. Stator Sensor: Is not getting voltage from the harness.

6. Fuses: checked each with a test light and are fine, the fuseable links on the side are getting power.

7. Ignition Switch: Checked continuity and everything seems good except for the 'off' and 'lock' positions from P1 to P2. I checked a replacement at autozone and theirs does the same thing. So I'm assuming that the switch is good.


Edit: Ok tonight, when I get home I'm going to put everything back on that I took off to test. I will check to make sure the injectors are pulsing. If I have to move on any further i'll check the ECM relay and then check all the fuseable links once I find them. If all appears good then I guess i'll have to start checking continuity in the associated wires. Thanks guys, i'll update this if I need anymore help!

If no fuel and no spark, the PIP and/or its circuitry are likely. A noid light is useful for testing injector pulsing (as you know, fuel-pump-priming gives one a warm fuzzy feeling but rules out nothing in terms of fuel system diagnostics).

I would confirm no spark and no injector pulsing, ensure all fuses and links and associated wiring are good, and go from there. I would have to look up the procedure to test PIP wiring (there should be a terminal on the TFI that gets the PIP signal, which can be convenient).

Then again, it could be something else completely. Good luck.
