Im in the process of trying to start my engine swap. A 3800 SC II from a 2000 Pontiac Bonnivile. Fuel tank has plenty of gas. Disconnected the fuel line to see if Im getting fuel,yes there is fuel (new fuel pump and fresh gas).No blown fuses and the fuseable links look good. Seems like Im not getting any spark, to the coil pack. I grounded the base of the coil pack (no change). What about the PCM, do I need to ground the case? Thoughts or sugestion , befor I have it towed to the shop. Thanks.....James.

The ignition module gets its ground through the wire coming off the harness not the case and the PCM also does not need the case grounded. Check to make sure you have both battery power and ignition power to the PCM. Is the PCM programmed as a Bonneville or did you reprogram it as a GP and wire the harness to match as some people do.

Also make sure you have power While Cranking not just with the key on.

Here is a good website for trying to track down ur issue. I have used it several times to troubleshoot no fire issues due to bad parts or wiring. The ICM harness is a known culpert of causing no fire issues from bad ground wire to the pin in.the plug getting pushed back just a little.

Quite some time ago,the PCM was programmed by Loyde at Fast Fieros. I asume he knew what he's doing. I may have goofed some where.

Also an easy place to mess up when making a harness is to mix up the two white wires coming off the small ignition module harness. Pin A goes to the PCM and pin E is for the tach if they are mixed up it will create a no start issue. Also check to make sure the plug is ok on the crank sensor as I have found a few over the years with bent pins on the sensor or the connector damaged. Dan
