Replaced eng now i have no power yo ign switch or

Look up check for clogged cat on youtube. Could be a coil braking down.. could be a egr problem.. could be IGN Module.. DO not replace these things.. there are tests that can be run.. Orellys auto parts can test them for you.. If the "bucking" is ign related it should set a code for engine missfire. A long shhot is grounds for the fuel injectors..each injector has 2 wires.. one power from the computer and one ground.. there usually grounded somewhere on the intake manifold or firewall.

start by checking fuse. if fuse is good, aquire a test light, check the test light on the battery to make sure the test light works. Power to ground = light. access blower motor under pass-side dash panel.(probablly have to remove underdash cover, secured with pop-in style fasteners.) locate blower motor. 2 wires w/connector Purple-power, black-ground. check for power at purple w/test light on known good ground, with ign on, and blower switch on high. if it has power, hook clip of test light to a power source, ( + on battery w a jumper wire) and probe black wire, with test light. if no light, jumper that wire to a good ground. if it lights, you have a bad b-motor. if no light on power side of blower motor, and fuse is good, check power to swith. blower circuit may have 2 fuses. 1 for high and a 2nd for the lower speeds. if switch has power to it, and power is transfered to another wire when switched, suspect the blower motor resistor.

have you replaced the ignition control module in the distributor

Yes, test the white wire at the vehilce's ignition. It should test at 12 volts DURING crank.

It is a timing chain, no mileage posted, it is hardly a timing chain have seen those eng well over 180k miles and still running with erraticll timing course, but most possible is a ignition module at fault. Hope it helps

it could be a vacuum line leak, or the vacuum actulator, also check to see if you have oil in the vacuum line under the truck if you do it would be the vacuum switch on the top of the tansfer case.

need truck scanned some auto stores such as auto zone / advanced auto scan for free check ur local area the trouble code will give u start point towards fixing problem

the tach should have a switch on the back for different amount of cylinders

one field wire to Negative side of coil. Power to power- fuse box that will cut off and on with truck, and ground to ground on the body are battery ground.

yes , i have a 96 mine done the same thing , i was removing the dash cover to install a radio accidently broke mine , i had to push down on what remained and wedged a sheetrock screw to hold it in place till i could get a new one
