Question about 1997 Ford Ranger SuperCab

1 Answer

Engine (97 ford ranger) stopped at stop lite and would not restart. Spark to plug wires, plenty of gas, good battery. after cranking several times, will start and run 3 or 4 sec. THE RELAY TO THE FUEL PUMP CHATTERS, I REPLACED THE RELAY AND THE NEW RELAYS ALSO CHATTERS. I believe I hear the fuel pump running, but the relay does not stay closed. I checked the wiring below the relay box and nothing appears to be shorted. The chatter only happens with the ignition on.

Just for the hell of it replace the fuse with a new one relative to the fuel pump also clean and inspect all electrical plugs and connections associated with the fuel system. There may be a bad ground with out the truck in front of me it will be difficult to go any further it is possible the pump is not creating enough pressure to close the relay have you replaced the fuel filter? If possible do a fuel pressure check at the fuel rail it should be 30 - 40 psi if not replace the pump.

You should have to get the truck scanned for codes, so there will be an exact direction to diagnose.

It could be you gonna have a bad valve cover gasket or the electrical connection that goes from valve cover gasket to injector.

It's also possible that the injector could be bad but you would have to test the electrical system to injector to determine that. I recommend you have truck scanned and we'll see what code it is and try to figure out what's going on.

I have a 97 Buick lesabre it'll die while driving the temp, battery, and oil pressure lights all come on it usually takes the car up to an hour to start. After stopped oil pressure will go to 20-25 but...


this issue sounds like u have a bad ignition control module,located directly under ur coilpak. thats wat they do wen they get hot aftr driving a while, shut off while driving(u must b loosing spark to ur plugs)an restarting wen cooled off. one way to check this for urself would b to purchase a spark checker at autozone or pepboys fairly inexpensive, an wen ur car dies, open the hood remove one sparkplug wire install tester between plug an wire, or wire an a good ground an have someone crank engine while u look at the tester bulb,if it lights up an pulses uspark is good,if it doesnt lite up at all while cranking engine ur spark is gone an thats ur problem possibly crank a sensor or the ignition module we mentioned earlier. try mounting the spark checker before the engine dies so u know wat a good spark will look like on that checker..... hope this helps good luck

TWO DAYS AGO 94 RANGER (4 CYL) SOHC...STOPPED ON ROAD. CRANKS BUT DOES NOT START. HAS FUEL PRESSURE. CHANGED FUEL FILTER. CHANGED AIR FILTER. CHANGED ONE OF THE DISTRIBUTOR COILS...TWO SPARK WIRES WERE NOT...


If all the coils are giving spark now,then you moat likely have gas fouled plugs now,so change them out with new ones,all 8 of them.If you do not have spark on all plug wires,pull the timing belt cover,and align the cam shaft and the cam,to see if the belt has jumped.If It hasn`t,replace the crankshaft sensor.

1987 Ford Ranger. Won't fire.


Ignition module comes to mind. If you've tested for spark (holding spark plug wire near the block when cranking) and the cap and rotor are good, it seems the module is the only other area left to try. Best of luck Patrick. Please post back with any other questions.

Engine won't start


in the engine.

1. you may be low in oil
2. poor electric flow. (spark plugs, high tension wires, etc)
3. bad compression
4. bad fuel-air mix

have a mechanic check.

hope it helps.
