    Thanks for showing a interest in this problem.I believe the pressure at the rail should or is about 45/50 lb. if I'm right then when you release the pressure through the relief valve or schrader what ever you call it should it at least squirt out a little not dribble,45 lbs. of pressure it should come out at stream of hi pressure mist,I'm open for ideas or facts and if i'm wrong then I'll have a hole new ave. to explore,in any case thank you again for your time and concern.

    How do you know there is no fuel pressure at the fuel rail?

You sghould check to verify that fuel is reaching to the rails. There is a possibility that there might be a fuel blockage before the rails

If you swop the coils, that will indicate if they are faulty or not.

Truck wont crank. we have put new distributor cap, rotor button, coil pack, plugs, wires, and fuel pump. we also checked our firing order.

you said you repl dist cap that means you don't have a crank sensor you have electronic ing module. remove your elec ing module have it tested most auto parts stores could test your module, or check your coil at the neg terminal. should have power. if not you lost your primary volt from your batt.your secondary power is coming from your electronic ing module from the module to the pos terminal on the coil, when the eng cranks,from the coil to the dist cap , from the dist cap center to the rotor then out to the plugs,this all happen pervided the timing belt or timing chain is ok. the cumbustion chainber needs 3 things , thats fuel, air, and spark.

Ford v6 carburated engine, pointless dist, ign module. eliminated key to a toggle and pushbutton but wont start when cranking over but as soon as let off button it will fire. voltage drop when cranking...

Did you just hook this up or was it working before? First batt voltage should not drop below 9.6v under load/cranking, second thing comes too mind is if your running a ballast resistor and where you have pos. wire for point less ignition-before or after ballast resistor alot of pointless ignitions want you to get the power before resistor so the ignition module has enough voltage to work with. also you can check voltage at coil during cranking to see- you need to be above about 7 volts or so. Also little known fact, if you have stater sol. on firewall/fender and you have second small terminal labeled "I" if you connect this directly to coil pos. it will apply full batt to coil during start only-by passing resistor.

First the car has NEEDED an oil change for awhile, and it starts and runs but it will randomly die, and will crank but wont start back up. If you wait awhile it will eventually start back up after quite a...

Check the crankshaft sensor or read codes off of the OBD-II system to see if that describes a problem that would cause the car to crank but not start and run on its own.

No spark, 1988 Toyota Camry 3SFE 4cyl, 5 speed.

there is no crank sensor on this vehicles 2.0L. If you have power to the coil, new coil, cap and rotor try this if not done yet>>>Unplug coil power first....Try pulling off the distributor cap, and make sure the rotor is spinning with the cam...If this fails to spin, inspect the entire distributor assembly. If it passes, Inspect all the power circuit and wiring to the dist assembly, if ok possible ecu. i recommend having a mechanic check it out!! Hopefully this helps...please rate...thanks

Car turns slowly but just wont start

Starter turning slowly sounds like:

- bad starter, or
- bad connection to starter, or
- bad connection(s) on starter relay, or
- low charge on battery, and
- and maybe some others... but these are most likely
