Please define "fire power". Is this just the power from the battery swinging the engine, or did you check if there is a healthy spark on the plug wires? If an engine dies without warning, the chances are very good it is the crank angle sensor in which case there will not be any spark on the wires even though the starter will swing the engine quite lustily without starting.

SOURCE: 92 gmc sierra no fuel to injectors

check the wiring under steering column. i had the same problem and thought it was a fuel pump. it ended up being a blown fuse because of some wires that were pulling out of a white wiring harness. it has about 8 wires or so on it and it plugs in to the harness for the column.

Check your fusible links; these are small wires molded into the middle of a bigger wire they are usually located up by the battery cables. When they burn they become discolored and softly flexible. Also check your relays too.

your injector or fuel pump may be going out, next time when you check the issue, check your distubutor again and making sure you getting sparks, if you do have sparks than it has to be your fuel problems.

Turns over but wont start.


Start by checking if it's a fuel or fire problem. Take a plug wire off and turn motor over.If there is fire, Take the hose going from the air cleaner to the throtle body off and spray a small amount of carb. cleaner in.If it's a fuel prob.,check the fuel pump relay (under the hood in a black box) (swap the relay out with another relay in the box ) If the relay is o.k., it's probly the fuel pump. If it;s a fireing prob., start with the coil and wires going to the coil.
