Coil packs? The 4.3 doesn"t use coil packs...The sending out unit is threaded right into the block come the appropriate of the distributor (looking at the engine from the front). If it to be unplugged I"d imagine press would review zero and not pegged yet I suppose it can be faulty. As soon as you turn the truck off does the needle go back to zero? If no you might want to check your gauge cluster to check out if the needle is stuck or perhaps the cluster itself is bad.

Thanks guys. Ns will need to remove the dist lid to watch if I deserve to see it. I just gained the tranny ago in and suspect possibly I bumped the while putting the dipstick tube earlier in. It"s tight back there! I removed the cluster and moved the needle ago where it need to be, but as soon as I rotate the crucial on, that pegs again. Part gauges peg once unplugged(open circuit), part peg once shorted to ground. Ns will inspect it an ext this weekend. The automobile was down due to the fact that Thanksgiving, so who knows what happened. Many thanks again, Later.

It"s come my knowledge that if the ECM isn"t getting any signal of oil push from the oil push switch - which would be the case, if the switch was unplugged - it cuts out fuel. Is the motor actually running differently, or is the problem minimal just to your dash gauge? Sounds an ext like a ground issue, or a difficulty with the gauge/cluster, itself rather than the sending unit, to me.Now would be a groovy time to upgrade to a mechanical oil pressure gauge. Simply locate the share sender in ~ the back by the distributor, screw in a T-fitting, and also then thread the share switch and the line for your aftermarket gauge into that. Don"t forget to wrap the threads with Teflon tape, too.
