OK guys iv tried just about everything. truck has new ICP,IPR,CPS,injector orings,wait to start light comes on,swapped IDM's checked all fuses, unplugged chip. still wont fire up will not even pull start. plugged scan tool in showed codes then erased them tried to start then bam no codes no wait to start light and check engine light on now what??? PCM bad???

 

[Bobby@cp]

What were the codes for? and if you have a CEL now what are the codes?

 

[95 stroker]

CPS codes and some Exhaust pressure

 

[95 stroker]

scanner will not communicate now either

Will the scanner turn on or is is just dead? First thing to check for the saner would be the fuses both in the cab and under the hood. The PCM fuse is the #9 under the hood and the one for the scanner power is the cigarette lighter/power port one in the cab.

all fuses are good scanner turns on just wont pull anything just say no connection

 

[Bugman]

I would say that if it isn't communicating with the PCM then the PCM just may be bad. Check the connector on the PCM and make sure that it hasn't come loose and you might even want to pull it to see if any water has gotten into it or corroded connectors.

Also just to make sure, when you pulled your chip was the key out of the ignition? If not you may of smoked the PCM

I cannot remember if the ignition was off a buddy was helping but i have to have a short somewhere because i get a buzzing sound through my stereo even with it turned all the way down. i have a truck i can get a PCM out of that is the same year and manual trans im debating on taking the whole fuse box wiring harness off that truck also.

 

[Justin@DP-Tuner]

My vote is a fried PCM.

Ok, Check the OBD II port and see if you have power, I'm not sure which pin it is but it has to have B+ on 1 pin. Once you get the scanner to communicate check for codes, Find out what your ICP is, then will the injectors buzz, check to see if the scanner is seeing RPM, and what you have for fuel pressure. One of those is going to get you going in the rite direction.
