Default 2001 Cranks but wont start P1193

The car started and ran for a few seconds then died. Now it will crank but it wont start. I pulled a plug and it looked clean (all 4 were replaced within 2k miles). I put a spare plug in the wire and turned it over with the casing linked to ground but saw no spark.

Prior to this I had just replaced all 4 engine mounts. This involved moving around the fuse box that sits above the driver side trans mount. The wire bundle there is really thick, so it didn't get moved far, just tilted upward to expose the mount bolts.

The other noteworthy thing is that the passenger-side center mount bolt broke off. I had to drill it out .. then the easyOut also snapped.. so i had to drill that out too. Ultimately i ended up drilling out the entire core of the bolt and retapping the hole. I collected most of the filings/dust with a magnet, but i do know that a small hunk of the outer shell of the bolt fell back behind the plate that's bolted to the engine. Anyone remember if the rear side of that metal bracket is exposed to the timing belt? I have a slight fear that the chunk may have landed on the timing belt and caused it to skip a tooth or maybe broke a position sensor.

Summary of noteworthies:
  • Moved the main fuse box when replacing Trans mount
  • <strike>Code 1193. unplugging IAT connector from the air hose doesn't help</strike>
  • Shavings behind the center mount bracket
  • RPM gauge doesn't move
  • No spark
  • Ran for a few seconds. Hasn't started since

Any thoughts on what to test/check before i start taking the timing cover off?

**P1193 is no longer on. I just cleared it and it doesn't come back after a handful of start attempts. It was likely only on from when i removed the IAT and started the car (thought it was the MAF).

Is the little red security light on the dash "on" all the time?

The red dot in the middle of the left gauge cluster? It only briefly comes on when the key is first turned. Both before and after that it remains off.

I think the P1193 code is a herring. I just cleared it and it doesn't come back after a handful of start attempts. It was likely only on from when i removed the IAT and started the car (thought it was the MAF).

I would suggest taking the Camshaft sensor off and see if the camshaft turns when you are cranking the engine.

Good idea. I just pulled the sensor and saw the cam spin when the throttle was blipped.

It's reassuring to at least know the belt is still intact. I just replaced it a couple thousand miles ago.

I would suggest checking to see if you have voltage going to the camshaft sensor. With the connector disconnected you shold be getting 5 volts on one wire, and 0 to 5 volts on another wire.

Cam sensor readings using black battery terminal as ground:
BrownYellow: 5v
Black 0v - continuity with ground
Orange: 8.9v

Test was done with the ignition set to ON, but not cranking.

Voltage is good at the Camshaft sensor.

Check to see if you have 12 volts at the ignition coil.

Tested Ignition coil wire with it disconnected, car on, not cranking. black lead in negative batt terminal:

Left: 0v not ground
Center: 0v - continuity to ground
Right: 0v not ground.


Thanks a lot for these suggestions.

Your welcome.

Do you get any voltage at the coil cranking?

Check the ASD fuse in the underhood fuse box. It might be blown. Fuse #13

The ASD relay powers a number of components:
It powers the upstream and downstream oxygen sensor heaters.
It powers the EGR solenoid.
It powers the ignition coil.
It powers all four fuel injectors.
It goes to the small square capacitor mounted to the left end of the cylinder head.
It goes back to the PCM.

The asd relay (E) is the same as all the other relays. You can swap it out with the horn relay (A).
