No u won't, does it start if u spray starting fluid in the throttle? do u have spark at the right time, bring #1 to top dead center compression stroke and see if you have spark at the time, if not the timing chain may have jumped, u did not mention the engine u have, so assume 6 cylinder..

I have an 87 Jeep Comanche 2.5 that would start one day and wouldn't the next. The engine would turn over but I wasn't getting spark. Turned out to be a defective crankshaft position sensor.

22004 ford ranger not getting fuel, replaced fuel pump 2 times in 16 months plus carb overhaul, what to check next?


Sometimes there is a plastic strainer in the gas tank and when they break down they will clog the fuel pick up. After the suction stops the pieces settle until the next time.

Ever replace the fuel filter or check for fuel getting through the filter?

Besides the inertia sensor which needs to be manually reset, some of these motors had an inline fuel pressure regulator. Another area can be a crankshaft sensor which adjusts fuel pressure to RPM.

Believe the inline pressure regulator works off vacuum so the "check engine light" would not diagnose. On the other hand, the crankshaft sensor should generate a trouble code. Curious as to what you find.

If you don't hear the pump running, it's likely not the fuel filter. However, you'll need to determine if the pump is getting power when it will not start. There should be a fuel pump inertia switch identified in the owner's manual. It's likely near the passenger side kick panel inside the truck. This is typically a convenient place to check for voltage from the fuel pump relay to make sure voltage is getting to and through the switch. There have been a fair number of folks that have had issues with the inertia switch failing. If you have voltage through the switch for about a second after the ignition switch is first turned to the Run or Start position, then you need to find out if the power is making it to the fuel pump. If there is no voltage to the inertia switch immediately after they key is turned to Run/Start, then you need to work towards the battery.

1991 dodge spirit.. ran great then next day wouldnt start. only starts when you put gas in the carburater.. changed fuel pump still wont start.. please help


usually if thats the only way it will start that means you have no fuel to engine. first off, check the fuse and relay for the fuel pump. next get under car at fuel tank and put your hand on tank while someone turns ignition to on. if the pump works. then you can feel it vibrate. a fuel pump only turns on a few seconds, to pressurize the fuel line. then when running its on all the time. check fuse and relay first before doing anything else. have a good one !!

My 2000 chevy S10 wont start I changed the battery and it ran fine for 2 days now it will turn over but won't start


Check Fuel Pressure. First turn key to on position (without starting) and listen for the fuel pump motor. If no motor sound, your fuel pump is not working. Check fuel pump fuse and relay. If fuel pump works, check for pressure at the fuel rail (schrader valve on fuel rail for pressure testing). If no pressure, or not enough, fuel filter might be clogged or fuel pressure regulator may not be working properly. IF fuel is not the problem, start checking electrical, such as ignition control and proper spark to plugs.

Changed fuel pump and fuel filter, now x5 2002 won't start


1. use scanner to find out if there's trouble code.

2.. it's not clear if the starter (motor) turns as you try to start the engine, if not, check starter motor including intermittent (maybe) problem with the ignition switch.

3.if starter motor turns everytime you try to start: check the electrical ignition system: coils & spark plugs

Have an 85 chevy 4x4. I just had the 305 engine rebuilt with a new intake and carb. It was working fine for a couple days and one morning I went to start er up and the engine just cranked and cranked,...


When you turn the key front. Listen for the fuel pump to prime. It should sound like a low humming noise that lasts about 3 seconds. If it does then check for spark by pulling one of our sparkplug wires and putting an extra spark plug in it. Place the end of the wire down somewhere safe and crank the motor. If you can't seek spark in the plug, it is most likely your coil failing. So, check fuel pump and fuel pump relays first, then spark. Good Luck.
