Thanks boss man, was the mechanic confused or does the breather valve sometimes located in the rear

No it's the rear vacuum, small hose like 3/16

Just wondering, obviously I don't know the proper name for the vacuum line on the back side o the valve cover, but my question that needs to be hooked up correct. The guy at the garage was fixing a totally different problem and lobbed off that line stating it isn't needed, now I just have an open hose there, he is mistaken correct? It is the open system no pressurized tank for coolant

Map sensor and a shorted out wire

I put two grounds for it in the bumper myself can anyone tell me is there something wrong with the distributor in this situation could it possible spark initially then stop

No if I keep the key in the start position it will continue to attempt to start goes in a cycle until I release the key

Okay took a voltmeter to every wire on the starter relay checked fusible links as well everything checks out with the key in both the on and start positions. i did notice that when the truck attempts to fire up the coil wire to the distributor is topping out at .7v is that common. and i have two grounds for the fuel pump

no dice on the volt meter checks out at 12v

so when the fuel pump primes up initially it should show 12v, should i also check it while turning over the engine, would that provide any insite

What would that narrow it down to, ill try it once sandy leaves and let you know

Missed a coma my bad bud

what would that narrow it down to ill try it once sandy leaves and let ya know

for the relay i replaced the 2nd one from front when that didnt change anything i went through each with the new relay and no luck is there anything i am overlooking i know a map sensor wouldnt cause it not to start it makes me feel like there is a fuse or another relay because there is never any variance in the symptoms

I have changed both fuel pump and ballast resistor I have also bypassed the resistor

Hey is there an available diagnostic tool for an 87 jeep Comanche like and obd I know there is the obdii but isn't usable for older vehicles that have the diagnostic center under the hood
