drase Posted June 12, 2010 Share Posted June 12, 2010 I replaced the CPS 2 weeks ago and the truck was running fine. Now I turn the key and I can hear the fuel pump and the power comes on, but the engine does not. No clicking sound at all. Does this sound like the starter is bad? I have a 6 cyl.

jimoshel Posted June 12, 2010 Share Posted June 12, 2010 Not the starter. The starter relay or the solenoid. The solenoid is what makes the clicking noise. It don't get the voltage from the relay, it don't click. Link to comment Share on other sites More sharing options...
ParadiseMJ Posted June 12, 2010 Share Posted June 12, 2010 First, check to see that your battery cables are in good shape, clean, grounded & tight. Assuming you have an automatic I'd be looking at the Neutral Safety Switch (NSS). Try to see if you can start it in Neutral. Do a search on NSS cleaning.

drase Posted July 6, 2010 Author Share Posted July 6, 2010 ParadiseMJ, you were correct. It is the NSS. The truck will start in neutral, but not park. My problem now is I can't get the damn switch off of the shaft. I've taken off the adjusting bolt, the tabbed washer, the attaching nut, and disconnected the connector in the engine bay. The switch will move a little bit up towards the engine but will not come off of the shaft. I've dowsed it with WD-40 and used flathead screwdrivers to remove the grime around and underneath the switch. I pull on it and it just budges a little bit. I do not know what else to do.

Eagle Posted March 21, 2011 Share Posted March 21, 2011 Personally, I'd just cut the wires and hot-wire the NSS. IMHO it's one more solution in search of a problem. Link to comment Share on other sites More sharing options...
hokie83 Posted October 25, 2011 Share Posted October 25, 2011 I finally (after months of procrastination) got around to pulling the NSS off my '89 Comanche. Not a fun task. The slot in the NSS hub and the shaft from the transmission had rusted together. I tore the NSS apart getting it off. Bought a new one, which I will install this week... after cleaning up the shaft so it will go on easily Link to comment Share on other sites More sharing options...
