I have a '97 cadillac eldorado, I have a code: p1376; ignition ground circuit; the problem with the car is that I get no pulses on the injector wires. What do i do

There are several ground connectors attached at the transmission end of the engine, on and near the throttlebody casting and down near the water pump/crossover front area. The connectors will be a simple ring terminal. try those first, then carefully unbolt each multi-pin connector from the PCM and remove/reinstall them. You might get lucky and simply have a corroded or bad connection. Beyond that, you're in GM scan tool territory.

i check all the ground wires , there good. i got a massage theft system problem car may not restart.

OK, you need to read up on ignition and theft system threads in here and up in Seville/Eldorado. There have been several posts on this over the last year and a half.

It could be the ignition switch, key fob, key, steering column wiring, or interaction from aftermarket equipment installation.

ok the car have remote start, and when they install the system they cut the pass wire and install resistor on the 2 white wires from the ignition switch to the harness. does that means they by-passed the factory alarm? if not then is the key no good becuase i get a crank and a spark?

needet to reprogram the computer ??? $140
