Question about 1988 Dodge Dakota

Open Question

I would like to mount a tachometer in my 87 Dakota

I would like to mount a tachometer in my 1987 3.9 liter Dakota. I have found that connecting the tach signal wire to the negative side of the coil (per tach manufacturer directions) does not work (no reading), I suspect it is bevause the negative side of the coil goes to a spark control computer, which interacts with a Hall Effect transistor in the distributor for spark generation. Where must I connect a tach to get it to work with this engine?

SOURCE: 96 Dodge Dakota .....NO SPARK

I had a very similar problem with my 95 dakota. I had recently changed my alternator, after which my truck would not start, due to no spark. I retraced all my wires from the coil and computer and came across a ground wire that i missed putting on when i reinstalled my alternator. It went under one of the alternator mounting bolts. after reconecting that ground wire the truck started and ran fine. Its amazing how something so simple caused me so much trouble.

Are there fuel filters in the canisters on the passenger side frame rail on a 87 dakota?

No, the fuel filter is under the hood, front passenger side of the motor. Look below the alternator. What you found on the frame is the "vapor canister", has to do with emissions.

Fuel pump location on 87 Dodge Dakota 3.9 V-6

Should be throttle body injected,if so in the gas tank. If it's carburated it's on the passenger side of the engine about mid-way down the front on the block,under the alternator.

87 dakota over heating

take it to a lube shop, and they have a vacum replacment system that will **** all the fluid and air out. put a vacum on the system then replace it with new coolant with out any air pockets. this should do the trick.
