Re: DSM Won't Start
Coils, fuel pump, injectors and sensors are powered up through the "ASD" relay (automatic shut down relay). Check to see if it is triggered or if it is check voltage output from it. From memory it is on the firewall on the left side under hood. If it isn't there hit me up, I'll check the book and pin it down for ya. Sounds like it is in that circut.

power transistor problem. its the ignitor, ignition module, whatever you want to call it. located under the coil on the side of the intake manifold. i have seen the plug installed upside down before, just check into it.

TPS Voltage?
Source should be 5V. If it's not, it's most likely the ECU.
Caps go bad in the ECU. (You can see them oozing on the board.) Catch it early, it's fixable. Catch it a little later, it eats the board, shorts out the IC's, and burns up the IC's on the board. At that point, it's not repairable.
So, Take a look and tell me.

Will check the asd in a minute and get back to you

Re: DSM Won't Start
Have fun looking for an ASD relay that isn't there.
If the car turns over, check the following:
CAS
Ignitor
Coil Pack
All relays
All Fuses
Coolant temp sensor
MPI relay
MPI Fuse
There are only 3 things that will cause no spark and only 2 things that will cause no fuel injection. And only one thing that directly fails both.
Also I assume since you said you check the coils that it's a 2.0 (since the 1.8 had distributor)

Re: DSM Won't Start
ya i never heard of it so i looked for it, then looked in the book, and looked on the internet and nothing so i kinda threw it away..
I checked all fuses
all relays
coolant temp sensor
Cas(no voltage)
i'll check the rest tomorrow

Re: DSM Won't Start
remove your CAS and all 4 spark plugs. Lay them across the valve cover above each cylinder such that you'd be able to see them spark. have them connected to the plug wires. turn the CAS by hand with the ignition turned to on and listen for the fuel pump and watch for spark.

Re: DSM Won't Start
i can't hear the fuel pump, no spark,(with the CPs off and spinning it with my hand with the ignition on). QUICKVIII mentioned a MPI rlay but i can't track it down. Nothing in the book shows it. Anything???
