I'm having so many issues with my 626 4 cyl. idle climbs to 2000 rpm then drops to normal constantly, fuel pump not working so i ended up grounding it at the fuel pump pin, coolant fan not working but relays and circuits are good. Removed the coolant sensor sensor normally would ground the relays at the pcm but now, no longer does. Everything points to pcm. I remembered at one time, I removed the pcm connectors to check for possible contact problems but now I realized I should have removed the battery terminals first. Did I damaged the pcm? Thanks.
