PLEASE PLEASE PLEASE HELP...

[LEROYBLACK]

THIS IS NOT A MUSTANG PROBLEM, BUT I REALLY NEED HELP. I HAVE A 95 FORD RANGER WITH A 4 CYLINDER. 8 PLUGS, 2 PER CYLINDER. ME AND MY GIRLFRIEND WAS TAKING A TRIP TO ATLANTA, AND BEFORE WE LEFT I PUT SOME LUCAS INJECTOR CLEANER IN IT, AND LIKE AN IDIOT I THEN FILLED IT UP WITH 93 OCTANE,(CAUSE IM USED TO MY 5.0) WELL WE DROVE FOR LIKE 1OO MILES THEN IT STARTED LIKE SURGING AND SPUTTERING, AND PUFFING A LIL SMOKE, AND THE CHECK ENGINE LIGHT WOULD FLASH LIKE IT WAS THROWING A MISFIRE CODE, THEN IT WOULD CLEAR UP FOR A LIL WHILE, THEN IT WOULD DO IT AGAIN. WELL WE PULLED OVER TO GET SOME GAS AND WHILE I WAS SLOWING IT DIED, I TRIED TO CRANK IT AND IT WOULD NOT FIRE. SO I PULLED THE PLUGS AND THEY WERE LIKE MELTED, SO WE TOWED IT HOME. I CHANGED THE PLUGS AND WIRES, STIULL NOTHING, SO THEN I CHANGED THE TIMING BELT CAUSE IT JUMPED TIMING A LIL BIT, STILL NOTHING, I HAVE NARROWED IT DOWN TO THE INJECTORS TO OPENING, IF I SPRAY GAS IN THE INTAKE IT WILL CRANK, I CHECKED THE FUEL PUMP AND IT WORKS, AND I PUT A NEW FUEL FILTER ON IT, AND THE FUEL PRESSURE AT THE SCHRAEDER VALVE IS LIKE 41 POUNDS, BUT THERE IS NO POWER TO THE INJECTORS.......ANYONE HAVE ANY IDEA.


I REALLY WOULD APPRECIATE IT ...

If you have no voltage on the actual injector harness wires I would say the computer is fried , but if you have voltage at the injectors but they arent opening then replace the injectors

Any digital multimeter set to dc voltage will tell you if you are getting juice to the harness, just unplug an injector, then have someone turn the engine over while you hold the multimeter on the contacts of the wire harness. Also, you could check your injectors themselves by setting the multimeter to ohms and reading the resistance when touched to the connectors on the injector itself. I know GM injectors should read around 16 ohms, once they get down to 14 or 13 you should replace them although I doubt this is your problem since it happened so fast.
