Car wont start...getting no spark
I was at the track (NHMS) today for a DE when my car just died on the main straight.
Here is what I know.
1. I have no spark at the spark plugs based on attaching a timing light.
2. I have fuel pressure.
3. The engine cranks over but does not start
4. When I turn the ignition on, I get this message "Reduced Engine Power"
Here are the codes I just pulled.
TCS - C1278 H
BCM - B2527 H
SDM - U1040 H
LDCM - B2264 H
I cleared those codes and tried to start the car, but still had no luck.
Anyone have a clue what could be the culprit?

Minifuse(s): 17,18,19,22,24. (check condition of fuses as well)
All these fuses are supplied by the ignition relay. If there is no voltage to the fuses, check the condition of minifuse 16.

With the key in the on (run) position, check for voltage at the following fuses in the underhood electrical center:
Minifuse(s): 17,18,19,22,24. (check condition of fuses as well)
All these fuses are supplied by the ignition relay. If there is no voltage to the fuses, check the condition of minifuse 16.

17 - 11.8
18 - 4.7
19 - 11.9
22 - 4.6
24 - 11.8
Note - There was no fuse in the #17 slot.
All fuses including #16 were all good.

Explain how you checked the voltage at the fuse locations....did you probe each side of he fuses with them installed, or did you removed the fuses, and check the fuse block.

Ok, your seeing a voltage drop becaue the coil packs are plugged in.
I'm working in Korea this week, and just got to work, so I can't stay online. If you PM me your email, I'll send you the service manual procedure.

JSTAN, pull the fuses and check them with ohm meter. In my opinion you can't have 11.8 v. on one side and 7.1v. on the other side of a good fuse. Maybe Lucky knows something I don't.

There are TWO ways to check voltage in a circuit. One way is attaching the NEGATIVE Meter wire to ground and reading the contact/s with the positive wire. The other is to read the circuit IN LINE. If you read the two small metal terminals on top of the fuse (attach the pos terminal to one fuse contact and the negative terminal to the other fuse contact),,if the fuse is GOOD,,,you should see ZERO voltage. If the fuse is bad (open) the voltage that NORMALY FLOWS THRU the GOOD FUSE, cant flow through the bad fuse and instead flows through the meter indicating a BAD fuse. SO,,,if you see voltage across a fuse, the fuse is BAD. If you see zero voltage, the fuse is good!
On the other hand,,,if you atach one meter lead to ground and read the metal contacts on top of the fuse, you should see the same voltage on both contacts. If you see 12 VDC on one side, and zero on the other,,,the fuae is BAD!
Hope this explains it so you can troubleshoot.

After I followed Bills response, I get 11.8 for all readings. I was measuring the voltage wrong.
