I turn the key and the starter just keeps trying to catch but engine never does. I've replaced the fuel filter, fuel lines and sensor in the fuel tank.

1999 Ford Ranger bad GEM module?

I have a 1999 Ford ranger 3.0 xlt 4X4 4 door ext cab. But today after replacing the instrument cluster light bulbs how ever during the repair I was listening to music on the trucks stereo and pulling tools out of the passenger side so all 4 doors where open not sure if it makes a difference. Anyways after completing the repair i noticed that my dome lights did not come back on and after further investigation neither did my speedometer or wipers/wash 4x4 switch warning chimes and power windows. However my key-less entry turn signals flash to pass high low switch still works. I looked at the pins and the connectors to the G.E.M there was no corrosion. So i was wondering if it could be the G.E.M. And thought I would ask before dumping $400 dollars on a new one.

How to shut off alarm for door ajar on my 95 Ford Ranger?

My alarm ding ding ding etc. Is ringing constantly whenever the my truck is running. The interior lights stay on continuously so I removed the bulbs for fear of a fire. I think the alarm is indicator for a door open. However, the dummy light does not stay on so I could be wrong as to what to do. Service station mechanic wants $88 just to diagnose the problem. He seemed to think it was the door open sensor which he says are now in the interior so needs diagnose which one involved or some such b.s. The $88 is for labor only for diagnosis only, and not for repair or parts.
