I recently picked up a really nice 1992 D150 5speed with a 3.9 v6 and I'm not getting any spark at all I checked power to coil there is nothing for power getting there wondering if It could be the crankshaft position sensor?? Any help would be greatly appreciated thank you

 

It doesn't have a crankshaft position sensor. You need to check power at the coil(positive 12+) fairly quickly after the key is turned on. The asd relay gives it power but it will shut off shortly after if it's not cranked over. Also check for codes...

Cycled key on/off on/off on and see no engine light flashing but also don't see it light at all when the key is turned I thought this model has a crank sensor it's by the transmission also checked power at coil no power at all even within the 2sec it should be on after turning the key to run

 

it does have a crank position sensor but it really sounds like the computer might be dead. do you see any check engine lights on when you turn the key to the run position even if it is just for a few seconds?

 

There is no light at all not even when you just turn it on for the bulb check could it be a blown bulb??

 

Possibly. Or, the previous owner removed it...... Wouldn't hurt to check.

 

you can check for a blown bulb but i would say it really sounds like it is dead computer if you are not getting the check engine light coming on for a few seconds when you turn the key on. you can also try checking fusible links but i doubt they are the issue if everything still works other than it not wanting to run
