I have a 1993 S-10 2.8 liter and needed to do a "panic stop' to avoid hitting another car. I did this by down-shifting and pressing the brake pedal really hard. Luckily, I stopped in time, but the truck engine will not re-start. The engine turns over, but will not "fire". Is there a "bump stop" switch located somewhere which would have disabled the fuel pump? If so, where would this switch be located? Any help would be greatly appreciated.

No inertia switch, sorry.
Start checking connectors and grounds. You may have dislodged a connector.

hum thats crazy

yeah gm dont use that switch instead they use oil pressure switch on engine in rear top by distrib

definitely check all wiring connections including at battery etc

do you hear the FP prime up a few seconds when you put key in run position?

if not then check relay and wiring


beat on tank with a big rubber mallet

check for 12 volts at orange wire at relay socket all times even key off

jump orange wire to gray wire there
it is on driver side by brake booster up high

pump should run and truck should fire up with these two wires jumped together

if it does then bad relay or fuse


if pump runsbut still no start then it probably ignition problem

chck cap and rotor for being worn burnt

The engine will run even with 0 PSI. oil pressure, don't beleive me, just unplug your sending unit.............

Not sure what you are talking about?

The clutch switch would not allow even engine cranking.
